Moderna

Swollen lymph nodes under both arms, urgent care, referred to ultrasound tech, mammogram, referred to general surgeon (awaiting appointment). Lymph nodes stayed swollen after first dose, got worse after second dose, and have been swollen since. Swollen lymph nodes in neck, hard to breathe, went to hospital, told it was just the vaccine and to wait it out. Lymph nodes in neck went down in swelling after 2-3 days. Irregular menstrual cycle, started approximately 2 weeks after first dose. Have had a menstrual cycle for 5 days every 9-12 days since first dose. Hospitalized for stroke-like symptoms (lost vision, couldn't form sentences) on 5 Feb 21. Discharged after CT scan and MRI came back fine.

Developed a large, itchy rash on my left arm on the 17th. It covers the majority of my bicep and is hot to the touch. It is painful to the touch and hot. It has continued until the 18th. Additionally, I started menstruating suddenly on the 18th of March.

Two missed periods since second dose (not pregnant), haven?t missed a period in 5 years prior to this

Started menstrual spotting roughly 24-36 hours after injection, despite not having had any menstrual bleeding since the insertion of the IUD. Some menstrual cramps, but nothing too painful.

It changed my menstrual cycle. It?s a delayed period. It doesn?t normally happen. I?ve also had hot flashes since the day I got the vaccine. I expect my cycle to start in a couple days, but it just isn?t usually late. I?m kind of scared to get the second shot, if it throws my hormones out of balance again.

After recieving the second dose of the COVID vaccine, I have an abnormally late period. Please make this side effect knowledge.

Severe headache, has continued intermittently until present. Strange menstrual flow, was very heavy, with clotting, unusual per patient

Since 12 Mar2021 I have had my menstruational period every day, give and take a few days. My second dose of the vaccine was on 25Feb2021 and my schedule period was on 2Mar2021. I have my routine period that week and then it began again on 12Mar2021 and I have not stopped spotting since.

My menstrual cycle following the vaccine (March) was late and I experienced much more severe painful symptoms along with it. I track my period regularly and start between day 28 and 30 every month. My period did not start until day 36 and cramping was severe. All of these symptoms were abnormal and I had no other unique changes to my diet, stress, environment, etc. within the month. The next menstrual cycle (April) was back on track with a 28 day cycle.

Woke up realizing that I had started my period and was experiencing horrible menstrual cramps (pain scale of 9 out of 10) and nausea. Took ibuprofen but vomited from pain. After applying a heated pad I managed to fall asleep. Continued to take ibuprofen regularly over the next 3 days as my cramps continued. Normally my cramps are between 4-6 on a pain scale out of 10 and only last the first day. I have never vomited from menstrual pain before, so this was very unusual.

Following my second dose of the Moderna vaccine, my period came two weeks early and was super heavy - gushing. I was in the middle of a birth control pack and always have on-time regular periods. I have never experienced anything like this. My period lasted 11 days and it usually lasts 5.

Caused abnormal extra painful and high volume period off cycle, about 10 days after just having a period

Increased menstrual bleeding following the vaccine. All typical menstruation symptoms which usually are not bad are now excessive.

Experienced period 2 weeks early. Unusual spotting before period started with bright red blood different from typical period blood (thinner and brighter red). Typically experience breast soreness 1 week before period which did not occur

Unusual menstrual cycle. I missed a period and then had a very short heavy period and then missed another period but have had spotting every day.

My mental cycle has changed. (Before vacation) Day:1-spotting, Day:2- semi heavy, slightly uncomfortable cramping with no painkillers needed, one super tampon and will switch to regular tampons. Change tampons after 2-3 hours of wearing them. Rest of cycle is light. (After Vacation) Day:1-spotting , light cramping. Day:2- very heavy flow, needing multiple super tampons. Cramps are painful-needed a painkiller. I had to leave work because of the bleeding and pain. Uncharacteristic of me. I haven?t had to ask to leave my job because of something like this before. Last month was a little heavier than usual but I didn?t think much of it. This month is just really bad.

The patient inadvertently received a dose of 0.51 to 0.52 ml as opposed to 0.5 ml. The manufacturer instructed us to reach out to the patient to let them know they have received a higher dose which may have the potential for increased local and or systemic side effects. Mariah reported that her period was 8 days late and she is normally very regular. No other side effects reported by Mariah.

Received shot at 11:08 am Friday morning. Struggled to fall and stay asleep ~12-5:30 am Saturday morning. 4:10 am: messaged a friend saying the muscle spasms/cramping was similar to a full body mild period cramps and it was probably why women were getting their periods early. ~1:30 noticed I had gotten my period about 2 weeks early. Did not notice typical body signs that period was about to start. My period has been inconsistent in the year of 2021. Some have been two weeks from each other, some have been 6 weeks. I typically notice increased acne and breast firmness prior to start of period. It could be a coincidence.

Blood clump fell out Saturday morning and began period, much heavier than usual, but previous cycle ended only 6 days before

Extension of period, extreme fatigue, brain fog, lack of appetite. Dizzy and naseous. Headache. Injection arm under arm pain. Increased heart rate.

Miscarriage less than a week after the second vaccine with Moderna. Estimated due date 01/07/2022, started with extreme dizziness and ended with Contraction like cramps and bleeding. History of very healthy full term pregnancies.

G2 P1 Patient with LMP of 4/2/21, EDD 1/7/21 received 2nd dose of covid vaccine and within a week experienced her first miscarriage. patient regrets getting vaccine and is upset/frustrated with the loss and concerned about future fertility

At the time of vaccination I did not know I was pregnant. I?m not sure if the vaccine had anything to do with what happened, but I would still like to report that on May 8th 2021 I started to miscarry. Any number of reasons could have caused this, the doctors do not know why, but it?s important to know I did get the first dose during the beginning of my pregnancy.

Irregular period- one period two weeks apart, other times without period for over 6 weeks. No irregular periods were had prior

Was 0 weeks pregnant at the time of the first shot and 4 weeks pregnant at the time of the second dose of the moderna Covid vaccine. At the 9 week ultrasound I was diagnosed with a missed miscarriage in which the embryo died at 6 weeks gestation. Cause of the miscarriage is own known. Occurred 2 weeks after second covid vaccine dose.

Since starting the vaccination series for covid, my menstrual period which is regulated by my medication Ortho Tri Cyclen Lo was irregular. It started a few days late after vaccination. I have not stopped bleeding since. It has been nearly 2 months of continuous bleeding resembling a menstrual period that just won't stop. Some days it is just spotting, others it is heavy. I have felt lethargic, low-energy, mentally foggy because of this. I have experienced menstrual cramps during this time as well.

Extreme arm pain in left arm beginning within 4 hours of getting vaccine. Extreme total body pain beginning within 24 hours of vaccine. Intensified menstrual cramps beginning within 30 hours of getting vaccine

patient reports period was delayed by 9 days compared to normal cycle. she felt regular menstrual symptoms (breast tenderness, increased chocolate cravings, etc) at her expected time of menstruation but period did not arrive for an additional 9 days

1 hour after- light headed, headache 7 hours after- body chills, body ache, fatigue 14 hours later- fever 21 hours later- cramps, back ache 23 hours later- started period (last regular period stopped a week prior) heavy than usual flow

I was at the end of my menstruation cycle when I received my first dose. When I got a period again in April it was delayed, insanely heavy (I have an IUD mine are usually so light I don?t where tampons or pads and my main symptoms are emotion and appetite related) but I was bleeding through multiple things a day. I was also in the worst menstrual pain I?ve ever had and almost went to urgent care. The next period I had after the second dose followed the same way. So painful I was doubled over at my desk screaming. I?ve also had 24/7 vaginal discharge which is never something I had before. And it?s A LOT of discharge. More than a panty liner could handle and I have to visit the restroom 10x more a day just to get rid of the discharge. It?s incredibly thick, sticky, and almost clear. There is so much of it that when I sit to pee, sticky strings of it will fall from my body. It has relatively little to no smell, and the consistency is almost like tapioca. I don?t know what to do.

I had cramps and heavy bleeding during my period after receiving the vaccine. I was also 2 days late getting my period. I have been tracking my period for 13 years now and I have a vary regimented cycle. I am not on birth control of any sort. And I also use a fertility monitor to track my fertility.

Menstrual changes: menstruation started earlier than expected (3 days early) and menstrual side effects were more intense than usual (cramping, menstruation was much heavier than normal). The period also lasted 9 days, whereas 5 days is usual for me. Additionally, I experienced persistent gum pain and sensitivity for a week and a half after my first vaccination. That also started on the same day as my early period.

Got the modern a shot in my left arm, with in 10 minutes, I began to feel like I was gonna pass out, I ended up passing out after sitting down for 45 minutes. The pharmacy called 911 ems came and checked out my vitals. They were normal by then. Then when I got home I began to bleed vaginally. I was in the middle of ovulating. ( not normal for me to bleed then) And now I am late for my normal period.

Heavy, painful period lasting approximately 2 weeks. Prior to second dose, I had not experienced any periods for the past 1.5 years due to birth control.

IRREGULAR MENSTRUAL CYCLE & MORE SEVERE PMS: My period came 1 week later than it should have and bleeding was inconsistent with previous cycles. It was spotty and very light over a much longer time frame. Usually, my regular cycle lasts 5 days, and this cycle began 5/27 and lasted for 8 days. My next period (June) came early starting 6/21 and has been much heavier than usual already. Pre-menstrual symptoms of heavy cramping, constipation, and fever started a week prior, reaching as high as 102.8F. and was on and off for two days. Nausea and cramping was severe for 2-3 days before 6/21 at the start of this June menstrual cycle. I have no been ill for any reason prior to receiving my second Moderna dose and when I met with the doctor on Monday 6/14 to discuss my symptoms, I was told to "keep an eye on it" with no specific diagnosis or recommendation.

Approx 4AM 6/19/21 is when I noticed I was experiencing vaginal bleeding beyond what I had ever experienced before. I was not due for a menstrual cycle. Between 4AM and 10AM I went through 3 overnight sanitary pads. Over the course of the rest of the day I went through 8 regular pads, soaking them through with blood. I contemplated going to the ER. The blood was excessive and bright red, freely flowing and passing clots larger than a dollar coin. The bleeding finally slowed around 36hr after it began. I used ibuprofen beginning the evening of 6/19/21 to help stop the bleeding. The bleeding finally stopped entirely the evening of 6/21/21. The most unique part is that there was little to no pain, even before I began to take the ibuprofen.

I am at my peak ovulation day today (28), have had a regular period since age 10, with no bleeding during ovulation from any point in time. I woke up at 6:48am with a hardened uterus and went to the bathroom at 7:00am. I saw that I had light bleeding within my underwear, which had just started.

Although I am on birth control and have a very regular menstrual cycle because of it, I have started my period today. I received my vaccine yesterday. I still have two days of hormones before the placebo pills and normally wouldn?t get my period for another week

I was supposed to get my period a couple days prior to getting the covid vaccine. My period never came and now I'm 26 days late. I've taken three urine pregnancy tests and they have come back negative. I'm supposed to get my period once again around the time I'm supposed to get my second covid vaccine. So I'm wondering if the covid vaccine could have an effect on my menstruation.

-Sore arm thirty minutes postinjection. Lasting approximately 72 hours -Mild headache 24 hours later, lasting only one day -Period stopped after injection and began again approximately 72 hours later

employee reports receipt of COVID-19 vaccine dose #2 on Thursday 1/21/21. C/o left thigh problem. Reports the following day post vaccination (Friday) had injection site pain, eyes were burning at work and general malaise. Reports she took tylenol and went home early due to symptoms. Reports fever up to 106.6 F Friday night which resolved the following morning. Now concerned about left thigh problem. States she woke up Saturday morning and when got out of bed left thigh was "off". States feeling like she is not able to walk normal since then, feels like she's "limping". Denies any falls. Patient also concerned about late menses. States she was scheduled to get it on 1/20/21 and wonders if this is vaccine related.

The day I got the first shot of Moderna Covid19 vaccine I was 4 weeks pregnant. Starting week 6 I start to have symptoms of miscarriage (January 14 2021). This continued until January 18 when I lost the baby. I was due in September 2, 2021.

I was expected to start my period on or around January 16. Today is February 10th and I still have not started. I have taken two pregnancy tests both after my missed period date and both were negative.

I had my second dose of Moderna on 2/10/2021. Experienced fever, Temp up to 101 F, for 48 hrs immediately after the shot. And had my period on 2/12/2021, which is one week earlier than normal. Moderna makes my circle 1 week shorter than usual.

1/8 vaccination HA went away after a week bleeding in between vaccinations ultra sounds weekly, blood work 1st went to ER, 2nd bleeding episode went to PCM for same day visit 2/2 miscarriage, D&C

I got the Covid vaccine on 2/13/21, I lost a small clot and started to bleed on 2/19/21. I was due around Oct 4th, at the time of the vaccine I was 6 weeks pregnant. I miscarried at home on 2/25/21- I lost a very large clot and was bleeding heavily for a week. Doctor confirmed with HCG test that I miscarried. This was my second pregnancy, I had my first child 1/10/20.

I received the vaccination on Friday and on Sunday my bleeding increased. I already had some mild bleeding that had been constant since Feb 23rd or 24th. But I had an appointment on Feb 26th that confirmed I had a baby with a healthy heartbeat. I was also diagnosed with a very small uterine cyst. They told me the cause of the bleeding was pro ant implantation bleeding. I had light bleeding (bleeding just needing one or two pant liners each day) until Sunday the 7 when I saw an increase in bleeding. I called my doctor on Tuesday (I decided not to call Monday because I felt I would get the same answer I had already gotten, which was that everything was fine) and they had me come in die an urgent same day appointment. At that appointment I learned my baby did not have a heartbeat. The baby was measuring at just over 8 weeks. The due date given to me based on my last period was October 12th. So I was exactly 9 weeks when I went into the appointment Tuesday to find out the baby didn?t have a heartbeat. I officially miscarried the embryo and the placenta on Friday March 12th. This would have been my second baby. My first is a male and he is 18 months old. My first pregnancy didn?t have any complications. I do not have a history of miscarriage in my family, and this was the first one I have had. I did have to take 150mg of Clomid to get pregnant with this baby.

soreness in arm at injection site that worsened the next day, heavier than usual period, scalp extremely itchy for a few hours after vaccination, elevated blood pressure, headaches

Severe disruption in menstrual cycle. Period came 14 days early, with significant difference in PMS symptoms, heavier flow, worse cramping and hormonal effects felt for 2 weeks after. Have Mirena IUD.

Complained of redness, swelling and itching at site within 24 hours of injection. The swelling extended up the arm and into the arm pit and side breast tissue as well as swollen lymph node. She saw her family doctor on 3.26.2021 and he referred her to an allergist, informed her to report an adverse reaction and not to take second dose of COVID vaccine.

-Hard raised red lump at the injection site that became present a week following injection -Early menstruation cycle: The previous bleeding part of the cycle concluded 03/07/2021. Patient began experiencing PMS symptoms around 03/23/2021, and bleeding began again 03/26/2021. Patient's period is almost always regular. Patient's periods typically last between 2-3 days, but at the time of this report has been going on for 4 days now.

from 3/21 until 3/28 i experienced on and off aches in my body, night sweats, dizziness, headaches and extreme fatigue. i also missed my period. i have seen a number of medical reports attribute missed periods to stress but i urge you to consider this a side effect of the vaccine. i get my period at the same time every month and it lasts 4 days every month because of my birth control. but i didn?t have a period this month.

Swollen and tender lymph node near my collarbone on my left side where the shot was administered. Upper back soreness on my left side. Sudden arm soreness. The same day I took the shot, about 1 later, I experienced severe cramping where I was uncomfortable sitting and standing, I could barely stand and walking was step by step. I also had my period at the time.

on 4/3 I experienced a fever (ranging between 99.5 and 100.3), headache, fatigue, and body aches. This began when I woke up around 7 AM and continued until about 9:00 PM. The next day on 4/4 I noticed a rash on my upper thighs and butt. They were just a bunch of red spots with white circles around them. I took benadryl and it was resolved in a few hours.

Irregular vaginal bleeding. Irregular because I?ve been taking birth control for 10 years and it occurred 2 weeks after my normal, regular menstrual cycle. Heavy amount of bleeding that lasted 4 days. Total days it occurred was 6, last two days were not heavy.

Menstrual period with significant bleeding lasting almost 8 weeks. Started off irregular for a few days, stopped and came back with an exorbitant amount of blood - needed a super tampon and pad every hour. Lasted about 7.5 weeks in total by using progesterone to stop the bleeding. Also significant cramping and pain. Both the heavy bleeding and pain with cramps are out of the norm for me.

I had a light fever on 04/07/2021. It lasted less than 24hrs. On 04/08/2021 I started having symptoms of a miscarriage. On 04/12/2021 I was confirmed I had a miscarriage. My doctor told me to go to the ER and that's where they confirmed it. I was 7 weeks pregnant my due date was 11/26/2021. They did said I was at high risk because I had a copper IUD that was removed.

My menstrual cycle came on 5 days early but when it came on I had large blood clots. I?ve never had my cycle come on early. I take birth control tablets the correct way and the Saturday when I started bleed, I had taken my tablet at my regular time that day. I also usually don?t have heavy periods at all so the amount of blood so early was unusual for me.

Body aches, fever, high blood sugars, diarrhea & extreme nausea-could not eat or drink for 2 days No clotting during menstrual cycle, EXTREMELY heavy and long flow

Irregular menstrual bleeding starting in the middle of birth control pill cycle (spotting with increased flow for 14 days), headaches/migraine, fatigue, joint pain (left knee and right fingers), blotchy discoloration and veins can be seen in a "lace-like" pattern on the back of both legs, some sharp pains in lower leg especially at night, return of rash/inflammation on arms particularly on right arm. Went to a clinic on 4/12/21 to ensure discoloration on legs was not a symptom of blood clots since my primary Dr. had to move my appointment out a week. Determined discoloration was not a concern and gave me a prescription for migraines. I have not taken the migraine medication as of 4/26/21. Primary Dr. appointment on 4/19/21. Determined symptoms were not a side effect of the birth control, but possibly the COVID vaccine. Ordered blood work. As a result, a CT chest scan was ordered due to high D-Dimer test results which was completed on 4/20/21 at the Hospital to check for PEs. Was also instructed to stop taking the birth control (still currently not taking ad will not start taking again). Follow-up with Dr. on 4/23/21 CT scan came back normal, but following up with additional blood work and ultrasound of both legs (scheduled for 4/26/21) to determine what the issue could be. Follow-up to discuss results scheduled for 4/28/21. Instructed to postpone second dose of COVID vaccine and take one baby aspirin a day.

My menstruation cycle began on March 28, approximately 15 days after my second COVID-19 vaccine. I have been experiencing a longer and heavier period than what is considered normal for me.

Missed expected period on 4/20/21, still have not started menstruating and I am on day 50 of my cycle. Negative pregnancy test on 5/1/2021

Reactions that cleared within 24 hrs of injection: Fever of 100.7 Chills Congestion Fatigue Achy muscles Continuing symptoms: No menstrual cycle in 6 weeks (first dose was 4/3/2021) Injection sight swollen, hard, hot, and red Headache

Heavier than normal menstrual cycle, more menstrual pain than usual, more intense emotional symptoms than usual cycles, longer cycle than usual.

Fatigue Change in period- April: 3 days longer and heavier flow May: extreme cramping, nausea and heavier flow

My menstrual cycle has been consistent (occurring every month) and there have been no changes for the past 10 years. One week before the 1st Moderna COVID-19 vaccine date, my period arrived like normal. Exactly one week after taking the first dose, I received my period once again (twice in 1 month). This is very abnormal. There were no other factors affecting my lifestyle. I believe the vaccine has contributed to my abnormal period and this should be made aware to all volunteers prior to receiving their vaccine.

My first menstrual cycle post 2nd vaccine was extremely abnormal. I had very painful cramping prior to my period and during the period. In addition, I had the heaviest period of my entire life. I was bleeding so much I had to use ultra sized tampons and change them ever 1-2 hours. This has never happened to me before and was very concerning. The heavy bleeding lasted 3-4 days. My second period post 2nd vaccine has still been a little heavy but is mostly back to normal.

Received the first Moderna vaccine on April 8th. I started my period as per expected on April 29th. My period lasted twice as long as my normal period. Typically my period lasted 3 days. My period then lasted 5 days and much heavier than usual. I received the second vaccine May 7. I started my period today and have debilitating cramps. Per usual I rarely have cramps and if so are mild enough to knock out with 1 ibuprofen. I have taken OTC and am still in a lot of pain. Unlike any period I?ve experienced. I also have menstrual cup, so I am able to see my flow is 2-3x heavier than usual. There have been no other changes in my life other than the vaccine. My younger sister also experienced similar issues and we got the vaccine at the same time. I reported because I saw other women were experiencing this as well.

In February I have been having abnormal vaginal bleeding, it was pretty frequent and it would last as long as three weeks of bleeding. Also during this time I had experienced fever, chills and was very fatigue. I sought care from my ob/gyn and she ordered for me to receive a trans vaginal ultra sound to make sure everything was okay, and the results came back everything was fine I was just experiencing abnormal bleeding.

I had a heavy minstrel cycle and I felt very fatigue and had chills and a high fever. My body was aching from 2am-10pm.

The day after my vaccine I started bleeding between periods which is very unusual for me. It messed up my menstrual cycle for about a month

Started period two weeks early, severe cramps, heavy bleeding. Began 8 hours after receiving injection. Flu like symptoms started at the same time. Still experiencing severe cramps. I?ve never had an early period before.

I received my second dose of the COVID-19 vaccine on 05/12/2021, two days prior to expected menstrual/period. I received my period as expected. HOWEVER, my next period was supposed to occur on 06/10/2021. I am 10 days late, and have been experiencing mentsrual cramps in my low abdomen and back pain for two weeks, with no period. My period has been late one other time in 27 years of life, and only by 5 days. I have never had such a late period, and I am not pregnant.

Moderna COVID?19 Vaccine EUA: dizziness, fatigue, local swelling/soreness in arm, menstrual cycle changes, tingles in hand and arm briefly.

19 days after my 2nd vaccine my period came 7 days earlier. I?ve been spotting blood for the past 7 days. This is not like my normal period, i have not had my normal flow since i began to bleed and my period is always on time and usually only last a maximum of 4 day. Im currently on birth control and have not missed any pills. I?ve been on the pill for 5 months and i also took a pregnancy test.

Menstruated twice in April; twice in May and then 3 times in June. In April, they were slightly heavier. In May, they started to get even heavier and even more painful. In June, I was bleeding extremely heavy. They lasted almost a whole week each time. I was in excruciating pain. I have an IUD. I was barely getting a period. When I did, it was light spotting a day or two prior to receiving the second dose of the vaccine.

Extreme chronic fatigue:9 or more hours of sleep at night. on days off, after being aways for about 5hrs, I end up taking a 3-4hr nap, then go to bed at usual time of 11pm. Still extremely tired when waking up, and have no energy to do anything during the day. Seems to be increasing worse. My doctor prescribed me Adderall to help me get through work. Intense Brain Fog: I used to have perfectly clear thought function. Now I struggle trying to remember what I was going to do, what I need to do, trying to get my thoughts out when speaking. At work, I have a hard time gathering my thoughts & what I'm trying to say when answering questions. Making obviously stupid mistakes, that I normally would never make beforehand. Menstrual Cycles: I've been on the same birth control & take religiously for 10yrs now and my cycle ran like clockwork. Now, I begin spotting half way through my cycle for about 5 days. Then when I do have my period, it is basically nonexistent. No real bleeding, more like black in color discharge & what seems like chunks, instead of normal red blood.

Irregular periods since vaccine: First dose - 04/06/2021 - period 10 days late Second dose - 05/05/2021 - period 10 days early 9 days into birth control pack (21 day pack - 07/04/2021) irregular bleeding started Went to GYN and they advised to stop taking pill to hopefully get cycle back on track. THIS HAS NEVER HAPPENED TO ME WHILE ON BIRTH CONTROL FOR 10+ YEARS. BE CAREFUL. THESE VACCINES ARE NOT SAFE FOR WOMEN.

The day after first dose was nauseous, fatigued and achy. Ended the next day. Irregular menstrual bleeding and painful cramps started at the same time but hasn't stopped since. Irregular menustrual bleeding and heavy cramps are still ongoing.

Breast tenderness, flush face hot to touch without fever, shot site pain. Muscle Aches mainly in back.

Miscarriage- received 1st dose of vaccine when approximately 4 weeks pregnant on 1/6/21. 1st ultrasound at 7 weeks on 1/26/21. Intrauterine pregnancy with yolk sack but no fetal pole seen. 2nd dose of vaccine at approximately 9 weeks pregnant on 2/3/21. Diagnosis of miscarriage on ultrasound on 2/8/21. Due date should have been 9/13/21

Miscarriage at 8 weeks of pregnancy, 2/14/21. Tissue passed naturally without medical intervention. Hormone levels dropped without concern. The week prior to miscarriage sharp sporadic headaches (migraine-like but only lasting a few minutes at a time and coming frequently) started, and have continued daily through today (2/22/21)

patient stated that her period started the day after she received the 2nd moderna vaccine which was early for her and cycle is normal now with 28 days in between.

While beginning my menstrual cycle at the time of my first vaccine, and having tracked my menstrual cycle regularly, from getting the first vaccine, the second dose of the vaccine to nearly present I had a 67 day gap with no menstrual flow when my cycle averages 35days between them according to the app that I track it on. The only change to my health or routine was the covid 19 vaccine.

Issues with balance, dizziness, and after traveling via airplane I have suffered severe Mal de debarquement syndrome- I usually get it for a few days after travel but it was 100x worse this time. Also abnormal minstrel cycle

I skipped my period after my second dose. I am not pregnant. I am on birth control for 10 years. This is the first time this has ever happened.

I started my period a week earlier than usual on 4/6/21. I received my second dose 2.5 weeks before then on 3/19. I typically do not get my period early, especially while on birth control. My stress and health are normal. I also had a fever of 102* and body aches starting 12 hours after the second dose and that lasted for 24 hours.

Heavy and painful period. I keep very close track of my period and usually I have moderate bleeding day one, cramps for 8 or so hours on day one, and then all uncomfortable symptoms go away by day 2 with very little bleeding day 2-4. This time, I have cramps for 48 hours and very heavy bleeding for 48 hours. During my period I was nauseous off and on, lightheaded most days and extremely fatigued the first two days enough so I couldn't work or get out of bed. This is all very different from my usual menstrual period and nothing changed in my diet or lifestyle from the previous month other than receiving this vaccine.

Dizziness and rapid heartbeat five minutes after shot with lightheadedness continuing for a few days after. Sore throat and swollen throat glands twenty minutes after shot that continued for a couple hours after. Swollen breasts leading to back pain twenty minutes after shot continuing for a week following. Headache, fatigue, and joint pain for 48 hours after shot. Nausea and acid reflux for several days after shot. Menstrual spotting occurring one week after shot (had period the week before). I saw a doctor at an urgent care and he suspects I may have anemia that was worsened due to being on my period right before shot and that likely contributed to the dizziness and rapid heartbeat. No explanation for other symptoms but I am healthy.

Miscarriage diagnosed at 14 weeks 0 days. At the time of diagnosis, fetus was measuring 13 weeks 0 days. Fetus was viable with + fetal heart rate of 165 at 13 weeks 5 days at routine prenatal visit.

Menstrual period started 1 week early and has lasted 12+ days, 7 days longer than normal for patient. Patient still on period.

Fever, Chills, Cold sweats, Body aches, Feelings of ear infection coming on, rash on injection site approx 5" in diameter, extreme swelling of injection site like multiple mosquito bites in one area. extreme exhaustion, symptoms lasted until mid-afternoon, got better for a few hours, then symptoms came back before bed. Symptoms mostly disappeared the next day except for body aches, sensitive inner ears (some difficulty draining the eustachian tube, they randomly pop, and some pressure is released). 3rd day most symptoms gone except still cannot fully release eustachian tubes, still mild swelling in arm light, and started menstrual spotting (day 15 of the cycle, my previous cycle started 4/1 and was regular.). 4th-day post vaccine and I am starting to spot more heavily, I think the cycle is about to start. I wonder if my body was stressed enough I did not ovulate. I experienced a change in discharge on days 2 and 3 but when I took an ovulation test it came up negative on both days, After the first shot, I felt like I couldn't take a full breath and I felt like something was in my lungs like phlegm or something ( I don't Smoke FYI) but I noticed the symptoms went away after the second dose.

red itchy and bumpy rash a week after the vaccine. My menstruation is much heavier than ever before! It began on Monday and usually it is just heavy for one day. But for the first time, it has been consistently heavy for three days.

After 3 days of receiving Moderna I started spilling ketones. My blood glucose levels remained in normal range even though I was spilling ketones. I continued to spill ketones for 3 days. When I had my period 3 weeks after first dose of Moderna it was heavier and longer than normal.

Period gets delayed. I took vaccine on April 11. Expect period date was around that time. It's been 15 days period does not start.

I was 19 weeks pregnant at the start of my 2nd dose. My due date is September 8, 2021. The morning after getting the shot I began to have vaginal bleeding. I went to my OBGYN to have the baby checked. I was referred to a specialist for a level 2 ultrasound. Everything was found to be normal with the baby. The cause of the bleeding is still unknown by the timing aligns perfectly with my vaccine. The bleeding increased and has now began to slow.

When i got my first dose March 27, 2021 it was fine about 2 weeks later I had a rash on my arm where I got vaccination. Around the same time (April 5th) it was due for my menstrual cycle and I did not get it until a week late. I am an individual who's cycle is right on track so this was very weird. I only thing I did different was getting the vaccine

Rash at injection site lasting 3 days, itchiness at injection site, body stiffness, delayed period with heavy flow and painful cramps.

Pain at injection site and fatigue the same day as the injection. Headache, body aches, menstrual cramping (not on period), fatigue, chills, sweats throughout next two days

I've been vaginally bleeding for 2 weeks. Bleeding began hours after the vaccination and has not stopped since.

High fever, chills, severe muscle pain in injection site, inability to raise arm used for injection, fatigue, confusion, delayed and more severe menstrual period

Patient got vaccinated at about 6-7 weeks gestation and 2-3 hours after vaccine had a napkin full of blood come out of her and then has been spotting since. Came in for appt 4/27 and was still spotting. Ultimately hcg levels kept increasing and as of 5/11 baby has HR 150 and is doing well.

I have not had my period since getting the COVID 19 vaccine - moderna. Starting shakeing 2 hours after and broke out in sweats, couldnt sleep but short term affects have since stopped. I am concerned about my period stopping after receiving this.

I had an extremely heavy period after my first moderna vaccine. My period was earlier than expected and I passed larger clots than normal.

Menorrhagia. My period usually lasts for 4-5 days. I started 05/10 and it is now 05/18 and I am still bleeding.

I was 4 weeks pregnant at the time I received the second dose of my Covid vaccine. This was unknown to me at the time. I had a miscarriage around 2 weeks later.

I have PCOS. Due to this I haven't had my period in over a year. Approximately an hour after receiving the first dose of Moderna, I was has severe cramps. Within 3 hours I had started my period. This is the only thing different in my life that could possibly have any effect.

My period started again after 3 days if taking my second dose. My last period prior started on 05/05/21

I have been on my period for 27 days now and it doesn't look like it's about to stop. I have never had any issues like this in the past, I believe it is related to the vaccine.

I was 16 weeks along when I found out I had a miscarriage. The doctors said the baby stopped growing at 15 weeks. The clinic measured the baby stopping growing at 14 weeks, right after my second dose. I?ve had 3 vaginal on time healthy deliveries. No previous pregnancy issues. This was definitely unusual.

Participant was 5 weeks pregnant when she got the shot due date would have been December 9, 2021. April 17th around five o clock started to experience strange feeling so she just continued to rest, said she was spotting heavy and participant got an ultrasound 2 days later and later on during the day said she heavy bleeding still. On April the 22nd the doctor told her she had a miscarriage.

Since completing the vaccine shots (Moderna), I have experienced amenorrhea (missed menstrual cycles). Also, I have experienced irregular menstrual cycles.

Bleeding from the vagina during and after intercourse. Intercourse and after was painless, I felt no discomfort at all but experienced large amount of bright red blood. I am not on my period and should not be for another few weeks. I have experienced bleeding after sex but never to this extreme.

I had chills and felt unwell about 13 hrs. after the vaccine. In the days following, I noticed my lymph nodes on my left side were swollen. This persisted. I noticed my supraclavicular lymph node was also swollen. I went to the Doctor regarding this. My first 2 periods after the vaccine were heavier. I went to my OB GYN because I wasn't sure if it was due to the vaccine or my IUD. It was not due to the IUD. I was also feeling super tired. I also experienced a full feeling in my neck so I got my lymph's checked. I got labs done which all came back fine. I was still feeling tired and having lymphadenopathy so I went to my PCP. Now, I still have the lymphadenopathy on my neck. It is not large enough to see. I also have a feeling of fullness in my neck. I also still have increased fatigue.

Heavy, irregular and painful periods after vaccine. Was on birth control with very regular and light periods. My period came 2 weeks early after the vaccine with heavy bleeding and passing large blood clots. Period will last for over a week, disappear and then come back 1-3 weeks later. Have had over 6 periods since shot.

Increase in extremely heavy periods. Prior to vaccination I would get maybe 1 heavy period every 3 or 4 months and the rest would be extremely light. However, every period since vaccination has been unusually heavy in such a way that daily activities are significantly disrupted.

Moderna COVID?19 Vaccine EUA. Swollen milk ducts in the breast in the same side as the vaccine including lactation. The patient is not, and has never been pregnant.

I have had aching and increasing discomfort to my left breast, very tender to touch and swollen since day 1 of receiving the 2nd Moderna vaccine. I have also been feeling intermittently nauseous. My eczema has been flaring up daily since getting the vaccine.

Miscarriage of pregnancy - conception occurred around the time of first dose. Shot given 5/7/21, miscarriage occurred 7/5/21.

Extreme changes in menstrual cycle. Prior to getting vaccinated, I experienced a regular cycle with light flow (no cramps) that lasted exactly 4 days (consistently, for the past 16 years). Since being vaccinated, I?ve experienced two abnormal cycles. The first cycle involved extreme pain and cramps, incredibly heavy flow that lasted for 6 days with spotting for 4 days afterward. The second, and more recent cycle was light and less painful, but I?ve been spotting for 7 days now. Every time I think it?s stopped, it starts back up.

Severe abdominal cramps followed by early menstrual cycle which lasted about a week. She has had menstrual cycles every 2 wks since then. Prior to COVID vaccines, her menstrual pattern was regular for a year (though she has a more remote history of irregular menses).

I got the Covid vaccine being 5 weeks pregnant and I went home and felt fine. On 7/23 the next day I experience a very high fever . But I felt fine otherwise . On 7/24, I began to have bleeding while I was urinating . I went to the ER that same day and I ended up having a miscarriage. I want to believe that the Covid vaccine was so strong on my body and I was so early in my pregnancy that my body was not able to hold out .

I was about due to start menstruation around the time of dose 1. I have not menstruated since late november/early december at this point in time. There is no possibility of this delay in menstruation being pregnancy related. I have no other known GYN issues.

January 4-6th I had severe headaches with no relief from Tylenol. 24 hrs after my first dose, I started my menstrual cycle which lasted till the 8th. Formally I was experiencing no menstrual cycle since being on the Nexplanon. Now I've had 4 menstrual cycles since being given the vaccine. From the 6-8th, I had diarrhea. Symptoms seemed to resolve on their own by January 9th

Dose 1- Severe pain at injection site, so much that I couldn?t move my arm. Dose 2- Woke up at 0300 with severe body aches and fever, lasted for 3 days. My period was due 2/9/2021, and it still has not come.

Reports she was vaccinated on 2/1/21, found out she was pregnant on on 2/3/21, and miscarried the pregnancy on 2/8/21. Additionally, she was involved in a motor vehicle accident on 2/1/21, prior to her vaccine, sustaining back pain and whiplash. Lastly, reports she began having visual changes on 2/3/21 and was diagnosed with a detached retina on 2/10/21.

Patient received 1st dose of Moderna vaccine on 3.2.2021. Patient has a subdermal implant (Nexplanon) and does not regularly have menstrual cycles. Patient reports the morning after she received the vaccine, she started her period. Patient contacted provider. Nexplanon was implanted 8/2018, and is due to be replaced this year.

I got my period even though I am on the IUD. I have not really had my period since getting my IUD. Normally I would not report this. But I am worried that the Moderna vaccine may have impacted the efficacy of my birth control since I do not get my period on the IUD. Will take a pregnancy test at appropriate time to determine fully. This must be researched as it has very frightening implications for unexpected pregnancy if it is impacting the IUD. Otherwise, my body was simply stressed enough by the vaccine that I have my period. It is odd either way.

I had just finished my cycle the day before. I woke up Mon morning to thick, clotted blood. I contacted my provider and I was instructed to take a pregnancy test, which was positive. I went in for an exam on the 12th and they confirmed that I was indeed pregnant. They tested my Beta Hcg twice. I didn't get my results immediately due to one site being closed due to COVID. I could've gone to the hospital and received the results immediately, but my doctor didn't want to take the chance due to the hospital having a lot of COVID. They confirmed that I was pregnant on the 19th or 20th. I bled for a few days after that. The final Beta Hcg was done and my level was 0.

3 days after the shot, I experienced menstrual cramping and bleeding two weeks before normal period start date. Four days of unusual spotting, discharge, and cramps have followed. Black discharge with a foul smell. I know this is highly unusual for my body. No other stressors and no history of irregular period. I will see my doctor soon, but my bloodwork from a few months ago was normal. I'll continue to monitor, but this is a concerning side effect and I hope it is temporary. I wish I'd known this was a possibility.

One afternoon of heavy menstruation. I do not usually have periods due to my IUD Diarrhea and cramps for two days. Fatigue for two days Cramps still ongoing

A few hours after the first dose: severe fatigue, sinus migraine and lack of appetite. Two days after first dose: I started mensturating heavily and suddenly with severe menstral symptoms. I continued to sporadically have light bleeding for 3 weeks. Prior to this event, I had not had a period in almost a year due to my birth control method. I have cramps, bloating, breast pain, irregular bleeding and weight gain. I received the second dose on 03/25/21 and by 03/30/21 I was experiencing yet another round of extreme PMS symptoms like severe breast pain, severe cramps that leave me bedridden, and intense food cravings. I have not had cyclic periods for several months prior to either of these events. It was jarring enough for me to start tracking my period symptoms because it was so out of the normal. I have been filtered into thinking any issues with my period are just something to deal with and to not seek medical attention, but I have missed approximately 6 days of work due to various symptoms after both of my doses.

Mild cramping; spotting; and it started about 04:00 on Sunday. I called my physicians' office on Monday am and was seen on Monday afternoon. Symptoms continued until about Friday. And then they stopped. No treatment was needed. Pregnancy history: 3rd pregnancy - for first pregnancy was full term; and second pregnancy ended in miscarriage; October 4, 2021.

I was scheduled to get to my period for that month on the day I received the second dose of the vaccine and never got my period for that scheduled week. I've been taking this birth control for years and have never missed a period for the scheduled week. The following month (March) I got my period on the regular sheduled week.

Menstruation was over a week late, experienced severe cramping and back pain as if I was menstruating during the entire week 3/15/21-3/20/21. Menstruation finally occurred on 3/22/21 and lasted the normal 5 days but was very heavy and painful.

Day after vaccine shot - fatigue and joint pain Day 2 - fatigue, joint pain, itchy rash on neck Day 3 - fatigue, itchy rash on neck, menstruated unexpectedly (period was complete 5 days prior and heavier than normal) Day 4 (Day of reporting symptoms - aka today) - fatigue, itchy rash on neck, heavier than normal and unexpected menstruation

I received both vaccines while pregnant and had a miscarriage at 11 weeks (found out at my 13 week appointment). I had COVID in November 2020.

Severe menstral pain although I was not actively on my menstral cycle. Ended period on 03/11/2021 and started heavy brown clot like bleeding one day after second dose on 03/19/2021. After second cycle one month later in April, have severe severe cramping and menstral pain.

for 36 hours after vaccine: starting immediately: sore arm in which injection occurred starting 4-6 hours after: fever, chills, soreness, and body aches extreme vaginal soreness and pain heavy menstrual-like cramping (but did not menstruate)

Pt did not know she was pregnant until a day after the vaccination. She as 6 weeks pregnant. On the morning of March 28th, 3 days after the vaccine, pt miscarried.

Cold and flu like symptoms for 2 days after initial vaccine and 1 day after second dose, including fever, chills, lethargy and overall tiredness. Have not had my period since administration of second vaccine

I started with the headache the day after the first dose of moderna vaccine. Since then and until today 18 days later it has not been taken away from me and it has been changing. Sometimes they are punctures, sometimes pangs that come and go and sometimes constant pressure. Also my period is 11 days late, which has never happened to me, it is usually early.

My mensural cycle began the same day that I received the vaccine. My period was extended to last a total of two weeks. At the injection site, a large red welt appeared and was consistently present for a total of two weeks. Being in the sun, irritated the welt and would turn it bright red and itchy. The welt would come and go for an entire month following the injection. For the first five days following the injection, my left middle finger acted as if it was jammed on and off. The finger ached and hurt and I was unable to bend said finger. I had a low grade fever for a couple days following the injection. One month after the injection, I formed an outer ear infection in my left ear and minor scrapes were not healing as they did in the past. Scrapes and cuts began taking weeks to heal instead of days. The ear infection lasted one week before I asked for antibiotic drops. The day that I received antibiotics, my ear infection spread to the right ear, and lasted another week. Both ear infections lasted approximately one week each. Also a month after my injection, my facial acne increased substantially and I began feeling lethargic with light throat irritations such as coughing and flem. Due to these reactions to the first Moderna injection, I elected to not receive the second injection. Five weeks after my injection, on 23 Apr 21, I received my TDAP booster and PPV23, one in each arm. I have never had reactions to vaccines prior to the Moderna injection; but now, for the first two days after the booster injections, I could not raise my arms due to severe pain and muscle aches at the injection sites. I felt weak and lethargic as well as experienced lightheadedness and rushes of blood pressure changes on 24 Apr 21. Currently on 25 Apr 21, I am still experiencing moderate injection site pains and feel lethargic.

Was pregnant at time of second vaccine should have been approximately 4 weeks but was not aware I was pregnant. At viability ultrasound there was no heart beat and it did not match with how far along i should have been. Repeat ultrasound a week later showed no growth and was diagnosed with a missed miscarriage.

While on continuous birth control which halts menstruation I began cramping severely. Within 24 hours I began my period. Approximately two weeks later I had signs of possible but not confirmed ovulation.

At around 0100 I began developing body aches, severe headache, chills, and joint pain. I also developed a mild fever of 101.3. I took Tylenol, took a warm bath with epsom salt and began feeling better around 0500-0700. I then slept 9hrs. Woke up ran some errands went home and was extremely tired. I then napped for 5hrs. After that I felt a lot better. I did have a pretty sore arm for several days but it was tolerable. The more concerning adverse effect I experienced from Moderna was after my first dose on 2/12/21, my period following that dose which was to be 02/23/22 was essential non-existent. I then had pregnancy tests done to confirm I was not pregnant. My period has since seemingly returned to normal.

I had my period 2 times this month (this has never happened to me before). I wrapped up my first period around April 17th.;1-2 days after my 2nd moderna vaccine I got all of this hormonal acne on my face that I never get normally.;On day 4 after my 2nd vaccine (so today Friday April 30th) I got my period AGAIN.

Day 2 - Extreme fatigue and disorientation/vertigo, and felt like I could not breathe. Went to Urgent Care and was told it was an allergic reaction. Was prescribed an over the counter antihistamine and told not to receive the second vaccine. Over the course of the following week pain throughout my body worsened - the most painful being in my ovaries, in my muscles, and (believe it or not) feeling like in my blood! I eventually stopped sleeping and psychosis developed. I was voluntarily hospitalized in an ER first, then in a Psych unit at Hospital where my psychosis was stabilized along as the primary concern while my physical health symptoms were monitored and managed with (what I assume was) patient-lead care. During my time in-patient I requested to stop taking my birth control pills, which was heard. Upon leaving the hospital (currently 2 days out), I have continued taking prescribed mental health medications (Geodon 20mg in the evening, Prozac 40mg in the morning) and continue to monitor and manage my pain with over-the-counter Tylenol. Since leaving in-patient the pain is localized to pelvis/ovaries.

I was on mensuration during time and have been bleeding and clotting ever since. Bleeding is still happening. I have very regular periods. So this is very new to me .

I had a baby. My second dose of the vaccine made me have abnormal spotting. I?m exclusively breastfeeding so should not have a period just yet. It could be a coincidence but the spotting started around 10 hours after the vaccine

Vertigo, tinnitus, dizziness, faint, fatigue, ache, swelling, anxiety, depression, irritation, unusual period, heart palpitations.

I got sick to my stomach almost instantaneously, I lost my taste for 3 days, I had fever and body aches for 3 days, my period became completely extreme I had blood clots which is not ordinary for me and it lasted an extra 4 days, my ears were pluged as well as not being able to move my arm for 3 days really at all, my throat was also sore and I had glands swell up

I have severe menstrual cramps and my period started today. But I have a Mirena IUD, and I haven't had my period in several years. I'm not sure if I should go to the doctor over it. The cramps are worse than I remember them being years ago.

Shot 1: sore arm and bouts of fatigue during three-week interim. Period is longer (9 days) and more painful than usual. PMS symptoms also endure for most of my bleeding, and bleeding becomes more heavy on day 4, as if I had a "second" period. Shot 2: 8 hours post shot, awakened with slight body aches. The body aches progressed to fever, headache and nausea between post-vaccine hours 8 to 12. From hours 12-27, I experienced a fever of 100, vomiting, diarrhea, body aches, chills, and insomnia. Fever initially not affected by tylenol or ibuprofen. I cycled tylenol and ibuprofen throughout the day. At hour 27 post-vaccination I was able to take 3 ibuprofen and slept for 3 hours. Woke up at hour 31 and fever was gone for good. Days 2-6 post-vaccine, experienced headache and joint pain concentrated on the side of shot. There was a bruise just beneath the shot that turned green and is still visible 11 days post-vaccine. Bouts of fatigue have not ceased since first vaccine. Onset of period is currently delayed by 4 days.

Irregular menstrual bleeding on Nexplanon. Currently now having monthly period and spotting, which I did not experience before the shot.

Heavy menstrual-like bleeding and cramping. I have an IUD and have not bled monthly for approx 4 years.

I don't believe this is due to the vaccine but I was still recommended to fill this out. I miscarried and my pregnancy ended in May. I got my first shot in February very early in my pregnancy when I wasn't aware I was pregnant. I then proceeded the get my second shot which at that I knew I was maybe 6 weeks into pregnancy. I've never been pregnant before and the estimated date of delivery would have been November 2021.

I have had an extremely heavy period for almost 6 weeks now. It has gotten worse this week with blood clots and bleeding through a tampon within 2 hours. I have severe cramps today. All things that are very unusual. My periods sometimes do not come at all and I never experience cramping due to birth control.

The first Moderna shot caused me to miss my next menstrual cycle, which had never happened to me prior to receiving the shot. In the week I received the 2nd shot on 3/13/21, I had uterine cramping that same day within a few hours of getting the shot. I also noticed a change to my cervical mucus during my ovulation cycle 2 weeks later. I then became pregnant the following month and was found to have a missed miscarriage at 6 weeks 1 day. It seems like their is a strong correlation between the side effects from the Moderna shot and the miscarriage.

Unexplained menstrual cramping began four days after dose and lasted five days. Cramping was moderate to intense and came approximately 14-16 days after the first day of my last period. My next period came as expected with some spotting beforehand. I saw other women reported menstrual changes so though this data should be studied, especially with all of the antivax rhetoric about the vaccine impacting fertility

On 5/19/2021 patient woke up around 11 pm with a sharp pain in her upper abdomen, then had emesis and the pain subsided and she went back to bed. On 5/20/2021 at approximately 7:30 pm patient started bleeding vaginally. She called the on call doctor and an ultrasound and office visit was advised for the next day. On 5/21/21, patient presented in office for Ultrasound and office visit. The Ultrasound finding were diagnosed for a missed AB (miscarriage)/fetal death in utero. Patient's due date was 11/4/2021. This was her second pregnancy, with the first being a Missed AB (miscarriage) in 7/2020. Due to CRL and failed on Miso prior, patient scheduled for D&C 5/27/21

I started my period on the same day as the vaccine. My period schedule is very normal and has consistently started exactly every 28 days for the past 10 years. After receiving the 2nd dose of Moderna vaccine, my period started on the 23rd day of my cycle.

I started experiencing a headache around 6 pm the evening of the 2nd shot (May 28). I took 2 Tylenol and felt much better. I started feeling achy and took 1 more Tylenol around 11:45 pm before going to bed. I woke up around 2 AM (May 29) with extreme shakes, fever of 100.4. I tried to drink some tea / water and I began having uncontrollable vomiting / diarrhea for about 3 hours. At that point I was lightheaded, and my arms and legs both became numb / tingling. My husband drove me to the ER and I was given 2 bags of IV fluids, nausea medication and pain meds. I am also on the tail end of my period and began having cramping. The doctors were very concerned about an elevated heart rate and believe I was possibly also having a panic attack

On March 29 2021, I received the first dosage of the Moderna vaccine. The second dosage was given on April 26th. I was just getting off my period when I got the shot on the 29th but it kept going afterwards. It has not stopped since then, including after the second dosage. Some days it is heavier, and other days it is very light. I have had a period for 4 months now.

Flu like symptoms day after 2nd injection, 24 hour bug. One week later, my menstrual cycle arrived one week early. My typical cycle lasts 3-4 days with light to medium flow/blood loss. Beginning 5/29, my menstrual cycle was 6 days long, had heavy cramping throughout my abdomen, back, and legs, and a continuously heavy flow all 6 days.

On the day of vaccine administration, I had severe body aches and my bones were hurting. I was very lethargic and blood pressure was continuing to drop. I drank about 3 bottles of energy drink to bring the blood pressure back up. I also had severe arm pain; the pain was so intense I could not lay on my left side for 3 nights. Miscarriage 4 weeks after receiving second dose of Moderna Covid-19 Vaccine. HcG beta and progesterone blood tests completed 48 hours apart to classify this as a miscarriage. Patient is having heavy vaginal bleeding and is feeling very lethargic.

Very limited information has been provided at this time.

Ever since I got my second vaccine, I have been spotting (bleeding). It's been consistent since the second dose in August and it's nearly July. I still have my period in addition to the daily spotting.

After receiving the second dose of Moderna I started feeling fatigue and sleeping more often. I was also having having menstrual bleeding for weeks on and off. Started getting Petechiae and did blood work. Platelets came back at count of 40. Prior blood work done in October 2020 7 months before receiving covid vaccine and platelets were at 246. I have no history of low platelets or any health issues until the after the vaccine.

Miscarriage occurred during 1st pregnancy since the vaccine. LMP April 6, 2021, diagnosis of blighted ovum on June 17, 2021. D&C on June 22, 2021.

Patient reports fever and chills at about 7pm after receiving her covid shot. She treated fever with Tylenol. She went to the doctor the following day and found out that she lost her baby. She was 5 weeks pregnant at the time of vaccination

Strong tingling/ pins and needles in left arm & hand multiple times a day since 2nd dose, still happening today 2 months later. Menstrual cycle completely thrown off, period arrived 10 days early and no subsequent ovulation

I know this is NOT a "live vaccine" but i did turn up positive for covid on 1/4/2021. my menstrual was delayed after shot by 2 days which is usual for me.

I was supposed to get my menstrual on 1/2 dint get it until 14 days later which is highly unusual. I did take several pregnancy tests results (negative).

body aches, lethargy, earache: within first 24 hours early onset of menstruation: 72 hours after injection

Pt is G1P0. EDD was 8/15 by LMP. The patient had an ultrasound on 1/6 showing a live intrauterine pregnancy with crown rump length measuring 8 weeks 0 days. She had covid vaccine 1/7. Came in with vaginal bleeding 1/29 and found to have missed abortion on ultrasound (no heart tones, crown rump length measuring 8 weeks 3 days). Underwent D&C 2/1.

After receiving the first dose, experienced severe arm pain, shoulder pain, and hand numbness. Acute pain and numbness has worn off, but there is still moderate pain when using the arm. About a week post-dose, began spotting. Was not due to have menstrual period for 2-3 weeks according to birth control pill pack, and normally does not have any menstrual symptoms (no period) at all. Bleeding has increased daily, and is now fairly heavy. Accompanied by cramps.

burning and cramping in the muscle under the site of vaccination (tricep area), itching on skin, bruising in armpit, pain and swelling on side of the breast, and itchiness in the armpit. All symptoms are exclusively on the side that I received the vaccination.

Fever 100.4-101 >48 hours Headache Chills, Muscle aches Ipsilateral to vaccine site Lymphadenopathy- axillary, breast, supraclavicular >48 hours Axillary swelling and tenderness Breast tenderness

I believe that the vaccine could have affected my monthly menstrual cycle (particularly ovulation), which (if it is documented by enough women) I feel should be looked into more so more women are aware. I've been tracking my period/ovulation for months for family planning purposes. I had 1st dose of Moderna vaccine on 1/20/21 and my next period on 1/28/21. I've been using OPK tests to track ovulation over the past few months, which have been positive on cycle day 18 or cycle day 19 (it's never been outside of those days before). When I tested using the OPK twice per day on 2/10/21 (Cycle day 14) through 2/17/21 (cycle day 21), I got all negatives. I have no idea when I actually ovulated in February and think that the vaccine may have moved the date up earlier (which never happened). I know that I ovulated sometime, since I got a very happy surprise positive pregnancy test on 2/25/21 (which conflicts with the infertility myths!). While our family is thrilled with the news, I wanted to report it to VAERS in case there could be a possibility that the covid vaccine could throw off somebody's menstrual cycles/ovulation. If there is a link between those two, I feel like women of childbearing age would want to be informed of that possibility!

Fever of 101F at 6 am, progressed to 102F in the afternoon. Fever broke by 2/28/21. Woke up with chills, sensitive skin, inability move the left arm due to painful injection site 2/27/21. The pain over the injection site progressed to itchy patch for 3-4 days. Stuffy nose, right sided migraine like headache that lasted 3 days. Started to have period like cramps 2/28/21, and had spotting to light period for 7-8 days, even though I have an IUD since August 2020.

Had a fever, chills, headache, fatigue until 36 hours past shot. These did not start until 12 hours post shot. I have since had a late period with no pregnancy.

vaginal spotting 3 days after injection, injection site delayed hypersensitivity reaction/RASH 8 days after injection

I miscarried with a blighted ovum. Pregnancy history. I have no medical conditions and have had 2 healthy pregnancies prior. I had the first vaccine the week I ovulated and then found out I was pregnant the following month. Jan 19th was the date of my last menstrual cycle Est il mated date of delivery: oct 26, 2021

Pregnancy occurred within the 8 days following the vaccine. Pregnancy confirmed with positive urine pregnancy test on 03/01/2021. Some vaginal bleeding began 03/12/2021 but resolved quickly. Abdominal cramping and bleeding on 03/15/2021 and 03/16/2021. Blood work completed on 03/15/2021 and 03/17/2021 showed a decrease in pregnancy hormone and pregnancy was considered miscarried.

Menstrual spotting and flow after 2 days of vaccination. Not suppose to occur until 2 weeks from this date.

1. Severe non-stop Migraine from next day 3/19/21 at 8am until waking up on 3/22/21 at 6am. Now I just have a slight headache 2. Pain at injection site for 3 days (red and swollen lump)- This has subsided 3. Tightness and pain in left neck (same side as injection)- This has subsided 4. My period was supposed to end on Saturday 3/20/22, but I am bleeding more heavily and this is unusual for me so I wonder if it is related to the vaccine somehow. Still bleeding as of today 3/22 Note: I treated the symptoms with ibuprophen and tylenol.

Early menstrual period onset 11 days after receiving the first dose of the Moderna Covid 19 vaccine. Period arrived 9 days earlier than scheduled with no recent history of irregularity in cycle. Two days prior to period onset I experienced very tender breasts and cramping.

Miscarriage of baby at 20 weeks and 3 days of gestation. Preterm labor. Due date was August 6, 2021. Baby was surgically removed on March 22, 2021.

I got my period one week earlier and experienced heavy cramping two weeks prior. My period is usually on time and I dont usually experiencing cramping.

After vaccine 1: My period was about to end (brown, light flow), when a few hours after the vaccine, it started being bright red again. After vaccine 2; My period started within 5 mins of getting the second vaccine. I got terrible back cramps almost immediately, which has lasted into a second day (unusual for me). They are so bad I can't stand up straight, or walk around.

Sore arm, irregular menstrual cycle, it was longer and heavier than normal with spotting for several days after which is very unusual for me.

Menstrual cramps (typically do not happen at this point in cycle) beginning day after injection. Cramps in conjunction with typical headache and stuffy nose side effects. Also had pinching pain in muscle of left arm where birth control implant used to be

After the first injection, approximately 24 hours later I got my period. With the period I had extreme pain, and my flow was extremely heavy. I had never had so much blood and fluid before in my life. The size of the tissue that I was menstruating was very very large and the pain and heavy menstruating went on until the end of the week (it never decreased or became better). Then after the second dose the same thing happened - not even 24 hours later I got my period with extreme pain, very large chunks of tissue, and extreme flow of blood. Then my third period the same exact thing has happened, extreme pain, very very large chunks of tissue, and extremely heavy flow.

Light menstrual spotting within first full day (less than 24 hours) of receiving first dose of vaccine. Occurred again two days post-vaccination just over 24 hours after first occurrence. Intermittent abdominal cramping noticed as well. I am a female that regularly tracks menstrual cycles, has a consistent 29 day cycle with a period lasting an average of 5 days. I have good knowledge of my ovulation window and am certain this is not related to any ovulation/implantation occurrences. It is too early in my cycle for that to occur. I am reporting so that you have this information but also out of concern that this could represent the onset of any other bleeding issues that may be developing as a result of getting vaccinated.

Received COVID-19 vaccine within 2 hours of non-OB transvaginal radiology appointment, follow-up appt related to finding from prior hospitalization for sepsis and pyelonephritis in late November 2020. Later in the evening after receiving vaccine, noticed bleeding that resembled normal menstrual bleeding. Bleeding ended within 24 hours. Menstrual period did not formally begin/return(?) until April 12. Experienced heavy flow going into the 5th day now, expect period to end soon as cycle normally lasts no more than 5-7 days. Suspect radiology and/or vaccine could be cause for delayed period.

Fatigue, Pain at site of injection, abnormally heavy off-cycle menstruation, lower abdominal cramping, rhinorrhea, weight loss.

Starting around 7 hours after the shot, I started to fell fatigued. My head also felt foggy. I went to sleep at 11pm, and awoke about every 3 hours. At 5 am, a terrible migraine set it. I took 1000 mg Tylenol and laid in bed for about 45minutes until it kicked in. At this time I also had complete body aches, but nothing hurt worse than my arm. The I slept another 3-3.5 hours. In the morning, the headache was less intense, the fatigue was still there but not debilitating, and the brain fog was present but minimal. I had nausea hit 3-5 times, but usually subsided within 5-10 minutes. 24 hours after the shot, I started spotting, mostly dark, chunky bits of uterine lining. I am not scheduled to start my period for 12 days. The spotting has increased - I?m now on my second tampon before heading to bed. I?ve also developed a small rash about 1-2 inches below the injection site, which feels warm, and is red in a rough square shape about 2?x2?. I still have a faint headache.

The patient received the first vaccine on 03MAR21 and began spotting on 10MAR21. A miscarriage was confirmed on 19MAR21. At the time of the first vaccine (03MAR21) the patient was unaware that she was pregnant as she had a negative home pregnancy test on 02MAR21. She was told by her OB/GYN to inform us of her miscarriage.

The symptoms included: persistent vomiting, severe menstrual pain, dizziness, numbness of extremities (arms and legs) and cold sweating.

I have unusual menstrual spotting. I'm not due for a period for 2 more months. I'm on the birth control pill. I've been spotting for over a week now.

This shot first caused an inflated heart rate, flushed cheeks, and then started my period. My second shot on 4/15/21 at the same place at 8:45 AM also caused inflated heart rate, flushed cheeks... but now my second period is over two weeks late which has never happened.

After both doses of the moderna vaccine, my menstrual cycle has become erratic. My menstrual cycle is becoming extremely short. My menstrual cycle previously has always been very regular. Typically my menstrual cycle would be 28 days apart with heavy bleeding that tapers at the end of my cycle. I am now experiencing menstrual cycles that last only 20 days and little to no bleeding. I am only ?spotting? while on my period now. Something is wrong and other women I know who have taken the moderna vaccine are having this issue just exactly the same as myself. It?s like my body cannot have a proper menstrual cycle. To add, I have confirmed that I absolutely am NOT pregnant.

The day after the shot (4/24/21) I had stomach cramps and oils not stop crying. The next day (4/25/21) the cramps continued, along with a massive appetite. The following day (4/26/21) at about 3:50am I woke up to heavier cramping and started my period a week early. I usually start my period at the same time of the month, but after the vaccine shot, period symptoms started and my period began earlier than normal.

Miscarriage; Patient was unaware that she was pregnant; This spontaneous case was reported by a nurse and describes the occurrence of ABORTION SPONTANEOUS (Miscarriage) in a 30-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch no. 011J20A) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below. The patient's past medical history included Pregnancy test (Negative home pregnancy test.) on 02-Mar-2021. On 03-Mar-2021, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 03-Mar-2021, the patient experienced EXPOSURE DURING PREGNANCY (Patient was unaware that she was pregnant). On 19-Mar-2021, the patient experienced ABORTION SPONTANEOUS (Miscarriage) (seriousness criterion medically significant). At the time of the report, ABORTION SPONTANEOUS (Miscarriage) and EXPOSURE DURING PREGNANCY (Patient was unaware that she was pregnant) outcome was unknown. The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown Route) was unknown. For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown Route), the reporter did not provide any causality assessments. No treatment or concomitant mediation were reported.

10 days after after my last period had ended, I had intense "spotting" (vaginal bleeding, about a tbsp of blood?) along with cramps, to the point where I thought I got my period again. Lasted only a few hours. I've never had this kind of thing happen to before, spotting is extremely abnormal for me.

My period is late and changed after my 1st dosage of Moderna. It seems like I am now irregular. I am waiting for my period to come on now but no signs as of yet. When I did have a period in the beginning of April, it appeared as if I was spotting for days - 1 week and no cramps.

Less than 24 hrs from getting the shot I got my period, I don?t get my period on this birth control, this was very abnormal, heavy bleeding and painful cramps, which I?ve never had in my entire life. Still have this 2 weeks later along with shortness of breath.

Sudden heavy mensuration that occurred two weeks earlier than expected despite oral contraceptives. Mensuration is ongoing and has not stopped as of yet.

Extreme fatigue that comes in waves, was having really stiff knees and my eye was twitching but after a few weeks that has stopped, periods have become almost non existent for the last 4 cycles

Missed period for 3 months- when it finally came back, it was very painful and severe PMS was experienced (which was unusual).

First dose: Fatigue for 48 hours after Period came early by over a week Light period spotting constantly since Second dose: First 48 hours: Arm pain, fever, fatigue, chills Period spotting has continued, very light, but constant, even 2 weeks post second dose. Spotting has lasted near 6 weeks now. No spotting before vaccine was normal for me. Never had it before.

I have not had a menstrual cycle since February 18th. I have also experienced heightened pms symptoms and muscle aches and pains.

Vaguely ill and nauseous for 2 days following 1st dose. On the 3rd day, period started 2.5 weeks early with severe cramping and heavy flow, much unlike usual cycle.

Made me get a second period. I never get two periods in a row. I also have been bleeding and have not stopped since this has occurred.

Typical response after second dose including full body aches, fever, chills, fatigue and muscle soreness at the injection site. However, about 4 days after my second dose, I began to menstruate even though I am on birth control and in the middle of my menstrual cycle.

Period started 7 days early, 7 days after vaccination. Period lasted 9 days instead of 7. Also had a random hot spot (splotchy & red, warm, did not respond to benadryl) on my right knee that would come and go for 2-3 days post vaccination.

I started my period on time but have had unbearably painful cramps. I don?t typically have cramps on my period but I?ve had to take ibuprofen all day.

Missed miscarriage. LMP March 7, positive pregnancy test on March 31. COVID vaccinations on March 18 and April 22. April 27, first ultrasound measured fetus at 6w1d (behind what was expected given LMP, should have measured 7w2d), embryonic cardiac activity was present, but could not be documented by M-mode. Provider warned 60% chance of abnormal pregnancy. BetaHCG testing results: April 27 was 28,247H; April 29 was 29,925H. A follow-up ultrasound on May 6 showed no fetal heart tones, and and fetus still measured 6w1d, unchanged from last visit. Provider prescribed misoprostol which was taken same day (May 6) to complete the miscarriage. Follow-up ultrasound May 13 showed gestational sac was gone and endometrium was less than 1cm in thickness.

Menstrual cycle has been off from normal. Period started 1 week after the 2nd dose and was very light, not a usual period, but lasted 8 days being very light/spotting. Cycle is normally ~35 days; however, period started again on day 18 and again was very light/spotting and lasted 11 days. Other side effects experienced (swollen lymph node under armpit, hives/rash near injection site, extreme arm pain, headache, fever) were reported already. Also still experiencing brain fog/slowness after vaccine.

Nausea with vomiting beginning 24 hours after injection, lasting 48 hours after injection. Residual nausea 72 hours after injection. Menstrual cycle began 12 days after last menstrual cycle, not due to start until on or about 05/30/2021.

Rec'd 2nd COVID vaccine on 01/28/21. Positive pregnancy test on 2/14/21 with estimated due date 10/26/21. On 3/5/21 scant spotting noted. Contacted OBGYN on 3/8/21, seen in the office. Ultrasound confirmed intrauterine pregnancy with gestation sac, yolk sac and possible fetal pole although measuring smaller than estimated due date. HCG/Progesterone levels drawn. Repeat HCG/progesterone levels drawn on 3/10/21 showed decline. Started miscarrying 3/10/21 morning following blood work. Seen again in OBGYN office 3/16/21 which confirmed complete spontaneous miscarriage.

Missed period, about a month late. Received second dose about 5 days before expected period. Pms symptoms the entire time. Confirmation not pregnant.

Menorrhagia causing weakness and inability to work. Hgb and TSH completed and normal. Pelvic ultrasound completed and was seen to be normal besides small ovarian cyst which per MD report was of inconsequential size. If heavy periods continue, treatment will be endometrial ablation.

Flu-like symptoms for the first 3 days: fever, chills, body aches, headache, itchy skin, pain in injection site (left arm). A few days later I started my period. It was irregular with severe PMS, panic attacks, anxiety and depression, severe cramping, more bleeding and blood clots than usual, period lasted longer than usual. Every day since I have been having PMS symptoms (anxiety, depression, panic attacks) and cramping. The cramping feels like period cramps but I am no longer on my period. The cramps last all day long and are not going away. I also had severe eye pain in my right eye about 1 week after the injection. The pain lasted for about 2 days, and was a throbbing pain behind my eyeball. I have never experienced any issues with my eyes before. I also had covid January 2021 and did not experience any of these symptoms then.

Day 0 (injection) : soreness, pain, and heat at injection site. Swelling of lymph node under left armpit AND lymph nodes at throat and mouth. Headache, fever (99.8F), chills, very strong shivering, fatigue, strong aches and pains in muscles, unusual joint pain, loss of concentration or brain fog, disorientation, drowsiness. Increased tinnitus. Sore throat. Chest tightness. Increased appetite. Day 1: soreness and pain at injection site. Lymph nodes at armpit and throat/mouth still a little swollen. Headache all day. Disorientation or brain fog. Major fatigue. Sore throat. Tinnitus. Lack of appetite. Day 2-4: Insomnia (inability to fall asleep, easily awoken, unable to fall back to sleep, unable to sleep for more than 3 hours at a time). Minor psychedelic visual effects (auras around objects, long tracers following moving objects, brighter or more intense colors). Headache (minor, all day). Drowsiness. Loss of coordination (minor). Brain fog. Day 4 specifically: Irregular menstrual cycle, my period immediately began 1.5 weeks early and very heavy. Flow is unusually fluid and more like the consistency of blood, not viscous like usual.

Pt began having heavy bleeding the day after the 2nd COVID vaccines reporting soaking 6 heavy pads in a 24 hr period that continues today at reporting on 5/25/2021. Has only had 1 episode similar to this and was in 2015. She historically is more prone to amenorrhea rather than heavy bleeding.

Heavy menstrual bleeding (menorrhagia), massive clots followed by bleeding, ongoing 11 days. Abnormally high compared to any menstrual cycle in entire life.

The day I received the shot I had fatigue and pain in all my joints as described though I am not sure if it was normal as I returned home at 10am and proceeded to fall asleep till 7pm even though the night before I had my regular 8hrs of slumber. The following week I was supposed to have my period. Instead I had abdominal cramping and the period did not come. It came 2 weeks after that (so 3 weeks total of abdominal cramping) aka my period was 2 weeks late. The period also did not discharge as normal (bloody mucus pieces over 5 days), it came out in one go as a decidual cast (with some bloody spotting for half a day tops). Honestly if I wasn't abstinent for 2021 I would have thought I got pregnant and just miscarried. After the decidual cast left my body the abdominal cramping ceased. I have previously never had a decidual cast and at most in my entire life, my period has been 5 days late. In addition, just 24 hrs after receiving the 1st dose and still ongoing today is that I erupted in cystic acne on my face, chest, shoulders, and back. I do have adult acne but on average I would have 2-3 pimples on my shoulders at any given time. After the shot I was sporting 15+ pimples in each of these locations. This may be hormonal acne due to the strange menstruation situation from above. I work from home and had to forge wearing a bra as the straps and bands would irritate the acne and cause them to form a 'head' and then rip open and burst from contact.

Extremely painful and heavy menstrual cycles followed the vaccine (March 25th, April 28th, May 27th). This is not the norm for my body to experience.

Menstrual cycle is off; one week early after first dose of vaccine, and now currently 2+ weeks late and counting after second dose. Not pregnant.

Patient was pregnant at time of vaccination (1 week) and proceeded to have a miscarriage 3 weeks following vaccination.

Irregular menstruation - menstruation began on June 3rd even though patient's cycle had ended two days prior to receiving the vaccine.

Woke up at 700 with tenderness and slight pain in left breast. By 1100 I felt like I had brain fog. By 300pm I noticed I had a slight fever (99.4). I took Tylenol and a 3 hour nap. I woke up with terrible joint pain, particularly in my knees, hips, ankles and wrists. All day I continued to have breast pain. I went to bed at midnight still I?m hurting. I woke up this morning still noticing the breast pain, but joint pain is gone.

after receiving vaccine on Wednesday 4/21, got positive pregnancy test on Saturday 4/24, 1 day after missed period. Estimated due date was 12/31/21. Began spotting on May 1 - approx 5 weeks pregnant. Spotted brown/pink with some clots until May 5, when I started lightly bleeding red. Beta tests on May 5 and May 7 showed 6228.7 and 6529.0, respectively. May 10 went in for viability scan - ultrasound showed gestational sac with 2 yolk sacs and 2 fetal poles, one measuring at 6 weeks and other measuring at 6w1d. No sign of misscarriage, no reason for bleeding was seen on the scan. Scan was perfect on paper. Bleeding picked up after scan and I lost the pregnancy on May 11 around 4:30pm. Bleeding continued for one week and HCG levels were low enough to show a negative test at my followup appointment 2 weeks later on May 26.

I noticed that in the way the blood came out on my mensural cycle very different. It was liquidly bright red and a lot of blood -- and I haven't experienced this in a decade. I feel like it reset the way my cycles have been in decades. And now I'm I was diagnosed with Endometriosis when I was 25 and for years now I've been super regular without pain. But now I am getting intense pain to the point of feeling like I would fainting with periods after vaccination and this hasn't happened in years. This started on my next cycle after my vaccination. I went to the Doctor May 27th to explain what was happened.

Heaviest menstruation of my life, causing migraines before the period, and once the period ends. I have never had heavy periods my whole life (age 12-31). I also am having some issues with fertility, which I hope isn't due to the vaccine.

significantly heavier menstrual cycle after receiving the moderna shot. I've been on nuvaring since I was 15 (so 15 years total) and i have never experienced heavy menstrual bleeding or spotting in between periods. After receiving the vaccine both started.

Patient was newly pregnant at time of vaccination. After about 2 weeks of receiving the first Moderna vaccine, patient had a miscarriage. Patient would have been between 4 to 8 weeks pregnant at time of miscarriage.

My menstruation has been extremely regular since 12 years old. It occurs once a month, at the start of the month, and lasts 5-7 days. It is heavy the first 2-3 days with intense cramps, then the cramps go away and it gradually lightens until it's done. However, since getting the first dose of the Moderna vaccine, I've had my regular period followed by maybe a week of no period, after which I start bleeding again. This bleeding does not come with cramping or any of the regular symptoms of my period: sore lower back, irritability, bloating, nausea, acne. The first time the extra bleeding happened was following my first dose of the Moderna vaccine and was extremely light, so much so that it was barely recognizable (a very faint light brown discharge). Every month since this first vaccine, the additional bleeding has continued. After getting the second dose of the Moderna vaccine, the bleeding has actually increased. It still occurs about a week after my normal period. Not only is it heavier each month, it occurs for longer. Now, for example, it is no longer simply a light brown discharge that can be taken care of with a thin panty-liner. Instead, I have to change a regular tampon a few times a day and wear an overnight pad when I sleep. It is mostly dark brown in color but when I wipe, there's sometimes a faint pink color. My first dose of the Moderna vaccine was batch # 006B21A and my second dose was batch # 032B21A.

Adverse event: alteration of ovulation and menstrual cycle. I have a very regular cycle that I track very closely with over 2 years of basal body temperature and cervical mucus data. Based on this carefully tracked data, I ovulate around cycle day 16-17 and have a menstrual period that lasts 2-4 days. After receiving the first shot of Moderna on the 11th day of my cycle, I continued to have low and erratic temperatures for 2 weeks. I did not observe any of the typical signs of ovulation. I took a pregnancy test which was negative. My menstrual bleed was also ~10 days delayed, and lasted for about 7-8 days which is over twice the usual length of my natural menstrual bleeds. The bleed was generally the same flow (moderate) as my normal bleed, but lasted much longer.

Swollen lymph nodes in upper neck and breasts 15 hours after shot. Breasts nodes still swollen. Neck nodes go up and down. Menstrual cycle 10 days after shot. Prior to both doses, cycle was EXTREMELY irregular. Could go anywhere from 67-139 days between cycles. This was 32 days. Shortest cycle I?ve had.

Alright so in late afternoon/evening on April 16th 2021, I went on a long walk which is normal for me. I noticed my yoga pants feeling tight and I felt bloated. When I got back, I had a lighter dinner. The next day I wasn't feeling well still and it was my Mother's birthday. I was feeling really weird and I just kind of ignored it. By the end of the day, after dinner, I started feeling really not great. I felt sick to my stomach, I wasn't getting sick/vomiting but then the next day I tried to go out to see my friends at brunch and just talked - I did not eat because it hurts to eat anything. I went to the store and got yogurt because it is all I could stomach. The following day I finally went to the ER because I was just really in pain, I said to my mom can you just cut out my stomach it hurts so bad. The pain was on my left side though, I'm not even sure if that's stomach pain. The DRS at the ER they did exams and they gave me medications for my pain but they weren't really sure what to diagnose it as. I got a stool softener, a nausea tablet and pain medicine. Most of that week I was still eating just yogurt. Also, mind you, I had started my period around this time and that made it confusing as well. I drove out to Iowa and saw my GI DR on May 11th 2021 in CA and he said well if it is all gone, that's great. So when my period came back, I began having the pains again. I was in pain so much that it hurt to even turn my body. That pain has continued to be repeated every time after the second dose of the vaccine. I saw my OBGYN on Friday July 2nd 2021.

Post vaccine heavier menstrual periods. 6 months post vaccine absence of menstrual period for 2 months (May and June). Next menstrual period on July 19th with heavy bleeding and passing large blood clots no larger than a golf ball size.

Miscarried at 7.5 weeks between vaccination #1 and #2. I do not believe the vaccine was a cause, however, it was recommended to report just in case. This was a second pregnancy, first miscarriage. EDD was 9-1-2021. First pregnancy was uncomplicated. Pregnancy tests were negative prior to receiving the first vaccine and then turned positive on 12-29-2020 (5 days after getting first vaccine.)

2nd pregnancy, at date of first dose (1/10/2021), 12 weeks 3 days gestation. on 2/2/2021 patient developed light vaginal bleeding. Ultrasound exam revealed no fetal heartbeat. Measurements showed gestational size 14 weeks 1 day (1/22/2021).

Menstrual irregularities. Patient is on OCPs and her period came early after both vaccinations- within 12-24 hours on both occasions.

Very early menstruation, occurring a couple of hours after the vaccine. It started as spotting that night, (I never spot) then a gradually heavier flow, working up to an unusually heavy & painful period over the course of the next 2 days. Also some very light clotting, which rarely happens for me. I was not due for my period for 2.5 weeks. My cycle is extremely regular and has never deviated from 28-31 days in the last 6+ years. I have a copper IUD (for 6 years), and have never been pregnant.

Day of vaccination: R arm soreness, (3rd day of menstrual cycle) 9:30pm heavier menstrual flow than normal Day after: 8am feverish/chills 12pm muscle aches, still feverish/chills, fatigue 5pm 99.8 (norm 97.6) fever continued chills and muscle aches and fatigue, headache, 600mg ibuprofen and recreational marijuana 6:30pm 99.7 fever continued chills and muscle aches, fatigue, headache 9:30pm 99.2 fever continued chills and muscle aches, fatigue, recreational marijuana. Heavier flow of menstruation. 2 days after: 9am 97.7 chills, fatigued 12pm: 97.7 fatigued, recreational marijuana 2pm: fatigued, menstrual flow very light My menstrual flow is usually heavy only the first couple days. It was heavier than normal on the 3rd night and continued heavy until over.

Pt is G1P0. At the time she received the vaccine on 1/26/21 she was 13 weeks pregnant. She had normal 1st trimester ultrasound and normal prenatal labs. Her EDD is August 5, 2021. On 2/9/21 she had a spontaneous miscarriage. No subsequent complications. No history of drug or alcohol abuse. No s/sx of other causes of a early 2nd trimester miscarriage. Of note the 1st trimester genetic testing was unable to be performed due to low fetal free cell DNA when she was at 10w. We were in the process of repeating the labs when the miscarriage happened. No history of COVID infection, no s/sx of COVID infection at the time of the miscarriage or subsequently. She was not tested.

Heavy menstrual period started day after vaccination. Currently breastfeeding and have not had menstrual cycle since October 2020. Menstrual cycle not expected.

Golf ball size lump on my arm at injection site that lasted 3 weeks and didn't reduce in size. Inability to use arm without extreme pain. Rash that felt like a burn on arm 12 weeks pregnant at the time of injection Pregnancy was lost

Received vaccine on 02/02, 4 weeks pregnant on 02/03 02/03-02/05: Severe lethargy, tiredness, pain at injection sites, fever all lasting 48 hours. Symptoms subsided after taking tylenol on 02/05. I'm not attributing this to the vaccine, but on 02/12, my hcg started to plateau and decline, no egg yolk or fetal pole was seen at 6 weeks (2/17). Sac was measuring at 5 weeks. I eventually had a miscarriage on 2/21

Moderna Covid vaccine received 2/26/21 at 1100 in left deltoid. Swelling of left upper arm (shoulder to elbow) began 2/26/21. Saturday 2/27/21 swelling continued and welts developed all around left upper arm (but not at the injection site). Sunday 2/28 L) breast began swelling and welt developed, breast was warm to the touch. All symptoms gone 3/1/21 morning. She is lactating.

Full body muscle aches Sore upper arm Delayed in menstruation by 2 weeks (negative pregnancy test - at home)

This was an IVF pregnancy. My 2nd pregnancy. I got my first positive pregnancy test on Jan. 27th at exactly 4 weeks pregnant. I received my first vaccine at 4 weeks 4 days. I then went in for my first ultrasound at 6 weeks 5 days. The doctor told me the baby wasn?t developed normally and a miscarriage had already started. I believe the gestational sac measured about 5 weeks 3 days.

Lump in left breast noticed on 2/25/21. By evening of 3/1/21 noticed discharge from left nipple which appeared to be colostrum and breast milk. By 3/4/21 same discharge from right breast.

Vaccine Saturday evening. Noticed ball of left foot feeling numb Sunday morning. Numbness spread throughout left leg during the day. Some aching but mostly numbness in the subsequent days. No loss of function. Left arm went numb Wednesday. Right foot and right hand developed some tingling/numbness Wednesday night/Thursday morning (today). Right leg has progressively gotten more numb today (Thursday). Vaginal spotting started Tuesday 3/9, only 1.5 weeks into my current cycle and current pack of birth control pills (highly unusual).

This is my first pregnancy. I had a normal ultrasound at my 8-week appointment, showing heartbeat and movement. My estimated delivery date was October 12, 2021. Four days after my second COVID shot, I had my 12-week checkup. They ran a urine test and asked me questions about my progress, all seemed normal. I wasn't exhibiting any side effects that would lead me to believe that I had miscarried. The OBGYN attempted to listen to the heartbeat but couldn't hear anything, so she wrote me a prescription to head over to the imaging site to get an ultrasound just in case. I drove there immediately and was given an ultrasound. They couldn't hear anything so we went ahead with a TVA. After approximately 45 minutes and no updates, the technician said that the results would be forwarded to my doctor and that they would reach out to me about the results. My doctor informed me that they could not hear a heartbeat and that I must have miscarried within the past couple days because the fetus length was as expected for 12-weeks of gestation. I am now scheduled for D&C on 4/5/21.

Early menstruation. I should be ovulating today and instead I got my period 2 weeks early with all typical menstrual side effects, bleeding, cramps, body aches.

The Monday I had blood test it was normal and progesterone was little low. I started miscarrying on Wed on 3/27. My estimated date of delivery would have been mid Nov. 2021.

Two days after my second vaccine dose, I woke up to heavy vaginal bleeding and cramping. My period started a full week early with worsened bleeding, cramps and discomfort. My menstrual cycle is typically regular and I was extremely alarmed by this change.

body aches, chills, headache, fatigue that began 15 hours after injection and escalated to severe for a few hours. Side effects subsided within 36 hours of vaccine. 9 days later- 3/20/2021- diarrhea for 72 hours, nausea, headaches, fatigue. 3/23/2021 severe bloating, constipation, irregular BM, that is still persisting 26 days later. 4/6/2021- menstrual cycle was due on 4/1/2021 history of very regular cycles, PMS symptoms ongoing for over 2 weeks and menstrual cycle is now 6 days late. Negative pregnancy test, not pregnant.

Started with body aches, then the chills came. Had a fever of 102 F. Worst headache ever. Tylenol/ibuprofen did not help with the fever or pain. Exhaustion. Also did not get my period that month. symptoms lasted for 3 days.

Exactly 30 days following my first dose of moderna, I experienced very heavy menstruation and severe cramping. I am on birth control continually and do not experience a period normally, so this was highly unusual for me. I have not received my second vaccine yet and I am not pregnant.

Approximately 30-45 mins after vaccine injection, I began menstrual bleeding. I suffered a miscarriage 3 weeks prior to the vaccination, and was not expecting to start my menstrual cycle. Since the miscarriage and up to the day of vaccination, I had light and inconsistent spotting (brown in color). However, after the vaccination I have had a light flow of blood, red/pink in color. My best guess is that an anticoagulant in the vaccine caused my blood to thin to the point where I began bleeding again from the recent miscarriage. The bleeding is ongoing as of the time of this report.

2 days after the first dose of the vaccine, I started cramping. The cramping was followed by 5 days of spotting just like the first dose. After 5 days of spotting, I then began my normal period (I?m on birth control). My flow so far has been way more intense then usual. My birth control tends to keep my period light, but at the moment I am bleeding heavily and cramping really bad. The cramping is intense (which I typically do not get during my period). I am again having cluster migraines. The PMS is more intense as well.

Spotting, prolonged bleeding during period, and heavy period. Currently bleeding for 3.5 weeks with cramps

5 days after the first dose of the vaccine, I started cramping. The cramping was then accompanied by a week of spotting, even though I was in the middle of my birth control pack and shouldn?t have been bleeding. The cramping was intense (which I typically do not get during my period). I also had cluster migraines and intense PMS overall.

I have the nexplanon implant as birth control, and my body stopped having periods two years ago because of that. After my second dose I experienced spotting for about three weeks and then it turned into a full blown menstrual cycle. It is very weird. It doesn't feel like a big deal but I also think it is important to note considering my BC reacts with my body reliably in such a way that I do not menstrate.

For the first time in my life I have missed a period. It has been 50 days since my last period. I attribute this to the vaccine as this has never happened before. I have also read other women?s periods have been impacted. I had the vaccine on 3/1 and still have not had a period. When I got the vaccine I had 103 fever, terrible chills, fatigue, and a headache. The fever started 8 hours post vaccine and lasted about 30 hours. The headache lingered for 5 days. These symptoms have since subsided.

Patient reseived Moderna 1st dose on 4/11/21 at Pharmacy. Developed some abdominal pain after 3 days on 4/14/21, and had miscarriage on 4/22/21, Estimated delivery date was 11/18/2021

Patient on 4/1/2021 experienced bruising, mouth blisters and heavy menstrual bleeding; 4/2/2021 saw her PCP; PCP advised patient to present to the ED. Patient was admitted 4/2/2021 and discharged 4/3/2021 upon admission patient plts were 3000; received plt infusion and started on IVIG

Since 12 years old my period has been clock work every 28 days, on or off birth control was supposed to get my period on April 7 did not receive until April 25. No chances of being pregnant, no changes in my life style or medications. Just almost 3 weeks late to the date, had not happened ever in 19 years!

Extremely unusual menstrual cycle. Usually my menstrual cycle is 6 days long. First day is light, second day is heavy, and then it wains from there. After receiving the Covid shot I started my period and heavily bled for four days to the point that I was soaking through super plus tampons every hour to two hours and having to wear heavy night pads. It was similar to bleeding after birthing a child. Then after the four days my bleeding stopped. On the fifth day I had severe leg pain in the upper right hip area. Then on the sixth day I started bleeding again. I?m on day 8 of my period. My period has never been this long.

I experienced a delayed menstrual cycle after both doses of vaccine. 10 days delayed after dose one and 4 days delayed after dose two. I'm normally very regular and never late.

After receiving vaccine, I drove home. I had immediate pain and tenderness in left arm. I experienced abdomen cramps. More than 3 hours later, but the same evening, I started my period. Two weeks earlier than I should have. I have been bleeding for three days and having cramps. This also happened my first Moderna shot on April 2nd. I had more severe stomach pains and started my period for only one day. However both times I?ve also had my regular period too. So 3 times between April 2nd and now.

Heavy menstrual cycle occurred in morning on 5/5/21, barely 12 hours after vaccine, with cramos. Just had period 2 weeks ago, usually cycle runs later, between 35-40 days. Rash on right arm, and arm pain/swelling/redness at injection site on left arm. Headache.

My menstrual period which has always been on time my entire life was 11 days late. It was due to occur on 4/13/21 but did not come until 4/24/21. I took two pregnancy tests in between those dates and both were negative. When my period did come the blood was darker than usual, the clotting heavier, and the cramping was more intense.

Very swollen and itchy arm with redness around the injection site lasting for 2 weeks with a fever. Absence of menses

Spotting started 4/28/21 continued until heavy, cramping, clotting period started 5/4/21 to date (today 5-9-21). Heaviness is starting to subside but still bleeding.

Began spotting five days after my first dose. This lasted for several days. My ovulation was a week late, making my whole cycle a week longer. My period was very heavy.

5 weeks pregnant, due date December 29, 2021. Next day after the vaccine fever 102.2 for 24 hrs, chills, dizziness, heavy bleeding the day after. Confirmed miscarriage on May 1st.

left underarm lymph nodes swollen, fever, sweats, chills, extreme headache, extreme body aches, excessive tiredness, vaginal bleeding out of cycle

Patient had miscarriage after 1st dose of COVID vaccine. Vaginal bleeding and cramping started after routine check at her OB clinic 4/22 showed fetal demise , Miscarriage complete 4/22/21. Seen by provider for pregnancy care per patient. Was around 16 weeks at time of 1st moderna vaccine- G4P1031. ER visit 4/22 reports she was supposed to be 17 weeks on that date but US confirmed fetal demise at 12w6 days. RH positive

I was supposed to have my menstral cycle 2 days after my first vaccine, and it never came. I experienced swelling and pain in my left lymphnode (armpit) and completely skipped my April period.

*2nd day of vaccine: Swollen neck and face, eyes are painful Since I received the vaccine until now, elevated blood pressure and heart rate. I've been normal with these in my whole life, now I have 136/85 or more sometimes 140/90 BP and my heart rate is more than 105. I am also delayed with my period, I am on contraceptive pills used to have period every 28 days but now I don't have my period I am delayed since then. Weakness, fatigue and headache until now.

I received my second Moderna shot on 4/9/2021. I was sick for about 36 hours and it went away. No big deal. On 4/12 I got my period. I haven?t had a period in 3 years because of my birth control. I had really bad cramping and lots of clots. It lasted about 5 days and was gone. On 4/30 I got another period. Same lots of clotting and bad cramps. That went away after about 5-6 days. I went to the dr on 4/13 and told her about it which she ignored and said it could be anything. She will run labs but won?t check estrogen levels since I?m on birth control. I go for labs on Monday 4/17. Well on 4/15, which is the day I am writing this I am again on my period. This isn?t normal. As well as the pains that I am constantly feeling in what feels like my tubes or something. I also know I am not the only person this has happened to. The shots have just became available for teens and I have a 14, 12 and 6 year. All girls. And I am all for the shot however this makes me question if it won?t affect my daughters and how it will affect them if it?s doing this to me. I am hesitant to give it to them and I wasn?t before.

Missed period for a week, not bleeding the right way, chills, sweat, watery mouth and dry cramps really bad.

Moderna COVID?19 Vaccine EUA Irregular menstrual bleeding. period-like bleeding only two weeks after last menstruation.

Stopped mensural cycle.. I had Diarrhea the next day following both vaccine administration, soft and pale stools ever since.

My period came 9 days early. (My period is always extremely regular at every 27-28 days.) I have never taken birth control. Period volume and cramps did not seem to be much different.

Ever since the completion of both COVID-19 vaccine doses, my menstrual cycle has been overly painful, long, and extremely (to an almost uncontrollable state). This has never been the case since I was 13 years old. My 2nd COVID-19 vaccine was the beginning of February, any by the end of February when my cycle started my period was out of control. It is now May, and has not resolved at all. Every month my cycle is worse and worse. It went from 4-5 days pre-COVID vaccine, to 7-8 days post- COVID vaccine. The menstrual cramps are so awful, which I have never had before. The flow/heaviness is so extreme and uncontrollable, I can't even leave the house for the first 2-3 days. This needs to be looked into. The ONLY thing with me that has changed, in the past couple of months is getting the vaccine. Nothing else would cause this. I have read some articles that are saying post-menopausal women are getting periods again and younger women are experiencing unusually abnormal periods. Please look into this and research it, as this is definitely not right

Missed a full cycle menstrual period. I have never missed a cycle previously is over twenty years. The next month (May 2021) extreme pain, fatigue, cramping and bleeding with my regular cycle. Intermittent spotting.

Had a very early menstruation within 10 days of the previous menstruation when period has been regular and tracked for years using an app. In additon it was a very heavy cycle and very painful. Now I've not had menstration for 40 days. After multiple at home pregnancy tests. I went to a physician and was tested and results are negative for pregnancy. She stated she is seeing multiple patients who are having multiple periods early or no periods and has asked me to report my experience to CDC.

6 days after getting the covid vaccine I developed painful urination, frequency and significant pelvic pain. I was diagnosed with Interstitial Cystitis 5 years ago and haven?t had any problems or flares for 4 years. Since I received the covid vaccine, I have been in a constant flare with the worst pain I have ever felt. Nothing seems to help.

During the time of 1st dose dated:04/04/2021 didn't knew I was pregnant. After second dose dated: 05/4/2021 we went for first scan on May 13th ,2021 and doctor suggested that the baby growth is not as per the weeks being calculated .They suggested that this might lead to miscarriage and asked us to come after 1 week date: 05/21/2021 .But soon after the visit I started noticing bleeding and spotting , we went back on Friday next week and there was no heart beat ,so they diagnosed it to be a miscarriage and gave medications following that. My blood reports and urine reports are normal. Wanted to report the event .

was diagnosed with trigeminal neuralgia, have had issues with menstrual cycle, thyroid issues, basal body temp has increased to a constant low grade temp.

My menstrual cycle has always been a little irregular but it has gotten substantially worse since the vaccine and I am unsure if it is related so erring on the side of caution and reporting. On may 9th I had profuse mid-cycle bleeding and was going through super tampons every 15 minutes for at least 6 hours. I went to the emergency room and tested negative for pregnancy (thus not a miscarriage) and my IUD was in place so my IUD that I have had for 2 years was not the cause of the bleeding. My period came back 2 weeks after that bleeding episode and has lasted for 13 days.

At the time of my vaccine I was 8 weeks and 5 days pregnant. A few days after my vaccine, I went to hospital 05-09-2021 with pain on my abdomen, and the pain migrated down more, like I had a blockage from being dehydrated. At the hospital they did an ultrasound and MRI and performed lab work. My abdomen was fine by the next day. My EDD: 12-10-2021.

Last Menstruated 6/2-6/6/2021 At 4:00pm breast tenderness and pelvic cramps began At 6:30pm spotting started At 8:30 pm one sanitary napkin of clots presented ? bleeding persisted, assumed second period has begun. 6/14/2021 Muscle aches throughout body. Joint pain primarily focused on hips and tailbone More bleeding than normal period, considerably more clots and blood is bright red; nor normal crimson clot colored like normal period. Breast tenderness still considerably worse than normal cycle.

1st moderna covid vaccine 4/20 /21 4/23/21 period was 1 week early and "intense" which was unusual for her as she is always regular Conceived in between 1st and 2nd doses 2nd vaccine 5/18, First positive HPT on 5/21 and again on 5/22 and 5/23. 5/24 Started spotting lightly 5/25 Bleeding heavily and cramping badly

My period began 3 weeks early. I had just finished my cycle prior to the vaccine, and it started by about 5 days after receiving it? And with all the normal period side effects. The period itself was more painful than I usual, as well?paired with hot flashes, which I?ve never had.

After receiving the first dose of my Covid-19 vaccine on 4/6/21 I had my period on 4/8/21 as anticipated. I received my second dose of Covid-19 Vaccine on 5/4/21 and was anticipated to have my period for the month of 5/8/21. I did not receive my period which was odd as I was on birth control. I waited a week and when my period still had not started I decided to take a pregnancy test to verify I was not pregnant. The pregnancy test came back positive. I proceeded to take 3 more tests for accuracy. I had my first visit with my OBGYN who ordered blood work to confirm pregnancy and verified my due date would be 1/13/22 making estimated conception 4/22/21.

Prior to receiving the second dose of Moderna on 4/16/21 my menstrual cycle was very regular, but since the second vaccine my cycle has been coming earlier every month. In May it came 7 days early, in June it came 10 days early.

Early menstrual cycle by one week, prolonged cycle extended to multiple days. Cycle used to start on the 24th of each month, has now started on the 16th or 18th of the month since April. Second cycle since the last dose has now last a week when it used to be 4-5 days.

COVID vaccines - states Breast Milk dried up 3 days after 2nd covid shot. Has tried VAERs a few time but had troubles completing the form. Has talked with pcp. States as a nurse knows to increase water and did this. States she was also in bed for 3 days post the 2nd shot with body aches, fatigue, and low grade fevers. No work up was necessary, but was really upset that her breast milk dried up as she was enjoying the bonding with her baby. States he was more cuddly than her daughter was. He seemed to miss it also but transition to bottles/formula well. He was 5 months old. She otherwise had no changes in medications at that time and did not take antihistamines. She has also noted heavy menstrual cycles (she is not sure if related or not) thinks a light cycle in December, but since March (about a month post 2nd dose) have been much heavier & longer. Lasting 7-10+ days, changes regular sized tampon about q2 hours. No known hx of prior covid infection.

within one month of second vaccine, patient reports very heavy menstrual cycles lasting 7-10 days and with increased frequency (less than one week in between cycle).

In April 2020 I was 5 days late from starting my period with a 3 day outcome. In May 2021 I was 7 days late with a 3 day outcome. And this month June 2021 I?m currently 6 days late from starting my period. I haven?t changed my diet,weight, or stress level also I?m not diabetic.

I have an intrauterine device (IUD) and because of this have not have a period for years. Since the COVID-19 vaccines were administered, I have again started regular periods and am also experience spotting in between periods. My period started up again 24 days after my first dose of Moderna.

I missed a period and my periods have been very inconsitent and very very headvy since then. Prior to the shot i had a very very regular period and not heavy at all.

MISCARRIAGE AT 7 WEEKS 5 DAYS GESTASTIONAL AGE, 1 PREVIOUS HEALTY PREGNACY IN 7/17/2019, NO PREVIOUS HISTORY OF MISCARRIAGE

Since getting both doses of the Moderna ( I got the second one on 4/22/21) my cycles have been irregular not only with when they appear but also the length of them. I had my baby and when I started my cycles up again in October my periods had been on a routine- starting on the second of each month and lasting 6 days and all that changed once I got the vaccine. Nothing else in my life has changed but that.

I had an extremely high fever and illness that started 24hrs after the second vaccine that lasted up to 4 days. I was running 104F fever for 2 days that OTC medicine would not break the fever. On 04/20/21 I had my LMP while severely sick. I found out I was pregnant on 05/13/21 and had a miscarriage at around 10 weeks on 06/29/2021. I have 2 prior children with no history of miscarriage or fertility issues and was seen routinely and early on in my care. I wanted to report this in case anyone is studying these kinds of events and would want the information.

Menstruation cessation with hormonal symptoms (weight gain, vaginal dryness, amenorrhea, skin changes.

IBS symptoms started and continue to persist. Foot numbness and bruising as well. None of these things were ever an issue until after getting the vaccine. Also experienced heavy periods 1.5 weeks after both vaccines even though my birth control doesn?t have me having a period.

Large red raised hive with itching and burning lasting for 6 days. Benadryl (treatment) Spotting for one day

Mentrual cycle is significantly heavier, more painful and period is starting 7-10 days earlier than usual.

My fertility had not yet returned after having a baby on 7/14/2020. I track my cycles using the Creighton model of Natural Family Planning and have for the past 7 years. This was my third child (all planned), and I have never had a problem identifying fertile periods and likely ovulation day. Exactly two weeks after my second dose of Moderna, my first postpartum period started out of nowhere. I had no fertile signs before. My instructor said that it could be a withdrawal bleed without ovulation, and that may be why I didn't see fertile signs. Given that it was exactly two weeks after my second dose, it could have also been that the vaccine triggered ovulation, and then I had my first period 14 days later. My period was extremely heavy (filling a menstrual cup in 30 mins-an hour on the first day), but that may just be because it was the first postpartum period. After it was over, I continued to not see any fertile signs. However, I must have ovulated at some point without showing a change in cervical mucus pattern because I am now pregnant. I therefore wonder whether the vaccine jumpstarted my return of fertility and also whether it somehow interfered with my usual fertile signs.

The patient has experienced a pause in her menstrual cycle that is typically very regular. She is experiencing extreme fatigue. She was sick with cough and extreme fatigue for 3 days after. She had had carpal tunnel surgery in March. In June (within one month of her vaccine) she began to experience vascular changes in her index and middle finger of the right hand. She has seen me twice for this. Her examination is normal to the digits but they are cool to the touch, painful and also have decreased capillary refill. No ulceration. On her follow up visit today she revealed to me that she had had the vaccine as we were revisiting her history again. I feel this could be a complication of the vaccine as the timing of the onset of her symptoms was far removed from surgery but closer to vaccine injections. She will be started on a full intensity blood thinner today. She seems to have not responded well to DAPT that was initiated at her first visit.

Headache began at 1:00 PM same day after receiving vaccine, with arm pain for 2 days. Unexpected menstruation on 1/6/2021, with intense menstrual pain more than experienced before.

Client was pregnant at time of vaccination. She had consulted with 2 OBGYNS that are following her concerning if she should receive the covid vaccine. They both stated yes. She received her 1st covid vaccination to her left deltiod between 12pm - 1300 on 1/14/21. She did not experience any complications or feel any side effects immediately after vaccination. She was monitored by nursing staff for over 30 min to be prudent. On 1/16/21 the Sat following vaccination she began experiencing cramping in her stomach and began to bleed vaginally. She consulted w her OBGYN and was monitored. She miscarried on 1/19/21.

I experienced mild soreness the evening of the shot and the following day, which resolved by 1/14. Mild fatigue was persistent since Tuesday 1/12. I started experiencing mild swelling and tenderness in my L armpit/breast, with mild pain during movement and compression. Yesterday (1/18), the injection site became slightly raised, blotchy, and very itchy. I woke up this morning feeling like I had a cold, with joint soreness and a mild itchy rash around my ankles, in addition to fatigue and warmth/itchiness around the injection site

I have a Mirena IUD and I started my period (for the first time since I got my IUD) 3 days after I received the vaccine.

There was very little pain until before bed the day I received the vaccine. At that time, I started feeling tenderness in the shoulder where I received the shot. The next day (today) the pain, inflammation, and swelling started moving down from my shoulder through to my fingers. I was barely able to get my wedding ring off because of the swelling. The tenderness now goes note my whole arm, under my arm pit, down my shoulder blade, and even my left breast. I have taken Benadryl for the swelling and tried to get it elevated, and I have taken ibuprofen for the body aches that I?ve had today as well.

1/4 - RECEIVED MODERNA VACCINE, PREGNANCY TEST CAME OUT NEGATIVE. 1/8 - PREGNANCY TEST CAME OUT POSITIVE 1/18 - HAD MISCARRIAGE, SAW TISSUE, NEGATIVE PREGNANCY HOME TEST, NEGATIVE HCT

I was pregnant, embryo estimated 6 weeks gestation. I started having spotting approximately 34 hours after the 2nd dose. I went to my OB for heavy vaginal bleeding with an ultrasound completed 49 hours post vaccine with no concerns visually. Estimated miscarriage <72 hours after vaccine administration with confirmation via ultrasound 1 week and 2 days after vaccine.

I conceived a pregnancy within 2 weeks of my vaccine which ultimately resulted in a miscarriage less than 6 weeks after the injection.

At the time of administration of the first does of Moderna vaccine, I was 6 weeks pregnant. I had confirmed pregnancy with home positive test and missed period. I had an estimated due date of 9/24/2021. This was my 4th pregnancy. I have had two uncomplicated pregnancies to term. In September 2020 experienced a chemical pregnancy with early pregnancy loss at 5 weeks. The first 24 hours after 1st dose of vaccine I experienced extreme arm soreness in the arm that was vaccinated, causing headache and unable to sleep. After 24 hours I felt "normal". 2 weeks and 3 days following the first dose of Moderna, I had a miscarriage. On the night of 2/15/21 I lost the pregnancy with vaginal bleeding, bright red blood, passing tissue, clots/ sac. I had an uneventful pregnancy up to that point, feeling well as I had with prior pregnancies.

I had arm pit swelling with a feeling of fullness. My right breast was larger kinda like filling the cup up and overflowing.

Complete missed period- have never been late or missed a period in my life. Only difference in the month was the vaccine. I track every single month.

I started bleeding on the 4th, doctor stated threaten miscarriage. I had blood clots and vomiting'. I was taking to emergency room. I was giving a DNC because I had a miscarriage.

Recurrent mild dizziness, mild, short periods, sometimes occasional mild headache. Dizziness is daily since vaccine was given. Seen by PCP on 2/17/21, diagnosed with vertigo, Exercises given, and dizziness is less.

positive at home pregnancy test 2/4/21 (same date as vaccine given). However, light bleeding/spotting started that night/next day but thought still normal. Heavier bleeding started 2/6/21 (Saturday) and continued through the weekend. Made appointment at hospital lab for Monday 2/8 to check HcG levels in blood. See below for details, but Dr. suggested repeat blood work on 2/10 as Hcg levels showed positive pregnancy, but very low. 2/10 Hcg levels slightly lower, which confirmed early miscarriage occurring.

sudden constant eruption of cystic acne on chin, back, and chest; not alleviated by any OTC medications. Menstrual cycles, post-vaccine, pain/longevity/heaviness incredibly increased.

I was supposed to get my period a day or two after I was vaccinated, but it was delayed by 10 days . My period has never been this late before, but luckily I got it today. Otherwise, my reactions were fine/mild, feeling tired and with a headache the evening of the shot and the next day.

I received my first dose of the Moderna COVIDI19 vaccine on 12/29/2020 not knowing I was pregnant. I took a home pregnancy test the week of 1/3/2021, which came back positive. On 1/17/2021, I started having some spotting and saw my OBGYN on 1/18/2021. My OBGYN did a transvaginal ultrasound and estimated I was about 5 weeks pregnant. I went for bloodwork prescribed by my OBGYN on 1/18 and 1/20 to measure my HcG levels. By 1/20-1/21 the bleeding became heavy and my HcG levels dropped. I had a follow up appointment with my OBGYN on 2/3/2021 where they performed another transvaginal ultrasound and more bloodwork to confirm that I had miscarried.

i had menstrual spotting for four hours in the middle of my cycle. spotting was at day 15 of my cycle

1st vaccine: December 31 2020 2nd vaccine: January 28, 2021 Positive pregnancy test January 29 (2 positive tests on January 29, and 2 positive pregnancy tests on January 30) Estimated Due date October 8, 2021 Miscarriage on February 15, 2021

Moderna Covid vaccine EUA. I believe the vaccine effects my menstrual cycle. It is normally 27-30 days. I have never ever experienced any cycle shorter than 27 days before. However, this cycle lasted only 20 days. I had bad dizzy and could not stand on my feet right when the period blood came out. I laid down and had some candies. The dizziness went away after 15 mins.

Very early menses - I am currently being treated for very long cycles but after receiving the Moderna vaccine I am now bleeding and am on day 11 of my cycle. My normal cycle for over a year has been greater than 45 days.

I felt fine after the shot until about 7 pm when I started experience an intense, pressurized sensation in my head, jaw, chest, and arms. This was accompanied by dizziness, nausea, fatigue, ringing in my ears, and feeling flushed. Over night I felt some numbness in my hands and arms. The next day the feeling of pressure and tightness was gone but the dizziness and nausea has remained. I have more energy but am feeling concerned about the persistent vertigo. I have a history of allergic reactions. I was also scheduled to begin my menstrual cycle this weekend and it has been delayed.

Received COVID vaccine on 1Feb2021 and was currently seeking to become pregnant. I concieved a child on 2Feb2021-4Feb2021. On 19March2021 it was determined that the pregnancy was abnormal and that I had miscarried, with likely diagnosis of blighted ovum.

I did not know at the time of the 2nd shot, but I was pregnant. I miscarried on 3/12. I was approximately 11 weeks pregnant.

Moderna COVID?19 Vaccine EUA Received 1st vaccine Dec 29, 2020, received 2nd vaccine while unknowingly pregnant on January 27, 2021. Had chills, fatigue, body aches night of 2nd vaccination. Found out pregnant Feb 7, 2021 at 4 weeks pregnant. Had blighted ovum/anembryonic pregnancy with miscarriage March 12, 2021.

1) Experiencing delayed period. My cycle is fairly regular and should have started within a couple days of getting vaccinated. As of 3/30/21 I have yet to start my period. Experiencing bloating, swollen breast, fatigue. Pregnancy test taken today was negative. 2) Suffered a fracture of upper left humerus, neat vaccine site. Injury was sustained during a fall while downhill skiing and may be unrelated to the vaccine, but the fracture was at the same spot as my vaccination.

Early onset of an extremely heavy period. A few hours after receiving the vaccine I began experiencing cramps, followed by getting my period 9 days early. My period was very heavy, very bloody for approximately 48 hours where I normally have a very light period throughout.

Very heavy period with clotting. I was on day 3 of my period at the time of vaccination. Immediately upon receiving the vaccine I had uterine cramps and heavy bleeding with large clots continued throughout the day and into the next day. Had some dark bleeding/discharge about 4 days after my period ended for 2 days. This also happened during my first dose of Moderna, although my first dose was on the first day of my period so I didn?t quite register it since bleeding is normally heavy at the beginning of my period. First period was also substantially heavier with clots and had some dark bleeding/discharge 4 days after my period ended

2 weeks after my 1st dose of the Moderna vaccine I started spotting blood as if I was about to start my menstrual period however I was not due to start my period for 2 more weeks. This bleeding was light and not heavy like a regular period. It did require a panty liner at times however. This bleeding lasted a little over 48 hours before it eventually stopped. My menstrual cycle has always been very regular. Before this episode I had never once spotted in between periods. This is very unusual for me. It has been 24 hours since the bleeding has stopped.

I had diarrhea about 20-40 minutes after receiving my first dose. I then got my period a few hours later. It was on time, however, it was extremely heavy. On the 3rd day, I began to have very large blood clots. I spoke to my gynecologist and she started me on birth control that sane day in order to stop the bleeding.

Within hours of receiving the vacine I began having vaginal bleeding spotting. By that evening it progressed to bleeding as if my menstrual cycle began. This was unusual because I just had my period. The last day of my previous cycle was 6 days earlier. This was accompanied by night swears and then a migrane that onset the following day along with usual symptoms of fatigue and a sore arm.

Since getting the first vaccine I began spotting within two weeks of ending my regular period, which is very unusual since I have the implanon birth control. I have been spotting/ bleeding for over a week straight now, when I should even be having a period at all. I also developed a slight yeast infection during the time between my two doses.

This is 32 years old,Unfortunately i had a worst experience with my first dose of Moderna, I got my first dose of Moderna on March 29 2021, My dizziness started 5 hours after getting the vaccine, and then i was feeling nausea, a day after on March 30 i felt a lot of pain under my belly, I did Urine pregnancy test at home and it was Positive, On April 1 My blood test pregnancy result was Positive too and showed i am 4 weeks pregnant, Everything was ok until April 10 that i realized I?m bleeding so much, It was Saturday i went to ER , They did blood test and Ultrasound and said you had a Miscarriage ????????? without any medical problem, Your blood test is completely normal and Ultrasound doesn?t show any problem like cyst or anything, I told them that the only reason is could be my vaccine and they said i should reported to CDC. I am vvery very healthy person, No alcohol, No drug, don?t tell pregnant people this vaccine is safe please please.

Menstrual cycle started over a week early and was very heavy with visible clots, swollen lymph node on left side underarm

After receiving the vaccine, my period started two weeks early and with much worse symptoms than usual. More cramps, worse nausea, a heavier flow, more migraines. As I am on birth control, and was only in the second week of it, this was very unusual.

Starting the day after receiving the second vaccine I experienced intermittent spotting that became lighter over the following week. This is highly unusual for me since I have an IUD and almost never get my period and very rarely get light spotting.

Extremely heavy periods since vaccination. Four cycles since first vaccination and all are much heavier and closer together than normal, and now containing clots which I have not experienced before.

My menstrual cycle started early and lasted two weeks longer than it normally does. My cycle is always very regular, so this change was very noticeable. My cycle normally lasts 5-6 days, and it lasted almost 3 weeks after my first dose.

I HAVE HAD IRREGULAR MENSTRUAL CYCLES SINCE RECEIVING THE FIRST DOSE OF COVID-19 MODERNA VACCINE 1/7/21. MY MENSTRUAL CYCLES PRIOR TO RECEIVING THE FIRST DOSE HAVE CONSISTENTLY BEEN 26 DAYS EVERY CYCLE-- UNTIL RECEIVING FIRST COVID 19 MONDERNA VACCINE MY CYCLES ARE LASTING 30+ AND THIS IS EXTREMELY IRREGULAR

Menstral cycle: heavier than normal and two weeks late. No possibility of pregnancy. Dizziness, sore arm, slight nausea for two days after.

I WAS SUPPOSED TO GET MY PERIOD THE DAY I GOT THE SHOT AND IT NEVER CAME. I AM VERY REGULAR AND ALWAYS START MY PERIOD ON TIME SO THIS IS VERY ABNORMAL. THE VACCINE IS THE ONLY CHANGE THAT HAS HAPPENED IN MY LIFE FROM MY LAST PERIOD. I AM NOW 4 WEEKS LATE AND I HAVE TAKEN 3 PREGNANCY TESTS NOW TO CONFIRM THAT I AM IN FACT NOT PREGNANT AND ALL HAVE BEEN NEGATIVE. THIS IS A SIDE EFFECT THAT SHOULD HAVE BEEN STUDIED AND DISCLOSED DURING CLINICAL TRIALS BUT UNFORTUNATELY WOMENS HEALTH IS ALWAYS A LAST PRIORITY IN HEALTH CARE.

After 1st dose on 3/25 lot# 008B21A I had a patch of redness on my right arm 2 days after the shot. I no longer get my period due to continuous birth control but started break through bleeding for 2 days. After the 2nd dose on 4/24- I experienced arm pain and that evening. The next day I had fever, increased heart rate, body aches, headache, nausea, and fatigue. That afternoon of 4/25 I started to get a rash on my arms. The next morning Monday 4/26 I woke up at 5am with a rash all over my body that itched and burned. This lasted for the next 12 hours. I continued to have nausea, fatigue and headaches for the next 2 days.

Menstruation cycle (period) started the day after the vaccine was given, which is when it was due. It's been over 3 weeks, and I am still having vaginal bleeding. My cycles have always been normal and consistent prior to this month. No other factors have changed, no pregnancy, no birth control, no stress, no diet changes, etc. The only thing that has changed is receiving the first dose of Moderna.

Same time of the month, every month for sixteen years, lasts 4 days)

Began vaginal spotting/bleeding that is outside of my regular menstrual cycle. Bleeding has been going on for over 3 days and is extremely heavy, soaking through a super pad every 1-2 hours. This is very abnormal for me.

Large itchy hive and tight chest one week later at injection site. Took antihistamine. Also experienced cramping and early menstrual period next day after receiving shot.

12 hours after injection: tiredness/fatigue and severely sensitive nipples. I am 12 months postpartum and breastfeeding. 4 days after vaccine started menstration (period) which was unexpected as I have not had a period the entire time I have been breastfeeding.

Menstrual cycle began much sooner than expected, was extremely heavy. PMS symptoms were much more severe than normal to include tender breast, cramping, fatigue and hunger.

My period was extremely late and has been completely unpredictable after getting vaccinated. I?ve been charting my cycle meticulously for three years (36+ cycles), and have always had a very even and predictable cycle of 25-26 days. My cycle remained a normal 25-26 days throughout the entirety of 2020 despite stressful events and changes in activity levels. After getting my covid shot, my cycle was as follows: 36 days, 18 days, 19 days. In the last three years I had my flu shot every season, and get all the recommended vaccines from my OBGYN when prompted. I?ve never had a reaction like this before.

Pt had Covid Shot on Wednesday. Developed period on Thursday and had severe bleeding. Went to the ER, and was found to be tachycardic. Received IV DDAVP for Von Willingbrand Disease. Physician unsure if reaction to COVID Vaccine, but requested report be made to VAERS. ECG shows patient to have Sinus Tachycardia, with moderate ST depression.

I have miscarriage - they aren't sure when it happened. The heart beat had stopped when they did an ultra sound last Friday. Pregnancy history - first; Estimated date of delivery - 12/31/2021

Heavier and longer menstrual cycle. Prior to the vaccine, did not have a menstrual cycle since 2/2020 due to breastfeeding and birth control. Prior menstrual cycles lasted 4-5 days with few other symptoms. After the second dose of the vaccine on 2/2/21, my cycle returned on 2/19/21 despite still breastfeeding and no change in birth control. For the next 3 months, my period has been longer (8-9 days), heavier, and with new bloating, low back pain, and cramps.

Impression: has always had regular menstrual cycles, after Moderna #1 had 30 days of vaginal bleeding, heavy at onset and has decreased over time, found to be anemic with +symptomatic.

I started bleeding vaginally 8 days earlier than my period usually would start. I am usually like clockwork, but I began my period 8 days early.

Vaccine series in Dec/Jan. LMP Feb 11. Breast lump noticed March 2. Positive pregnancy test March 14. Bleeding April 10, miscarriage April 14. D/C April 16

Irregular periods. I had a normal period Feb 10 (after 1st dose) which was 30 days after previous period which was normal cycle for me since recovering from covid but did not have normal cycle again until April 25, and cycles now seem to be 35 days long. Blood work and monitoring done by OBGYN, has not yet resolved. Also experience hair loss similar to experience after having covid but less intense. Still experiencing.

Had my first vaccine dosage on 3/26/2021, second dosage on 4/23/2021. I did last ultrasound on 4/22/201, baby was measuring 8 weeks and 4 days with a heartbeat of 174. The baby stop growing 9 weeks and 1 day on 4/26/2021.

I currently have a IUD and don't get a period. Its now been 4 days of heavy cramping and 2 days of a very heavy menstruation. Neither are normal. I have never had such a heavy flow or such intense cramps. I've bled so much in the 2 days that I'm bruising easily now.

Stomach cramps, upset stomach, fatigue, muscle aches, lower back pains, diarrhea, nauseous, it's day 10 from 2nd shot and my period has not arrived yet, I'm late a week

I?m on birth control so I have a period after I?ve finished the active pills in my pack. However, after I received the second dose of my Covid vaccine, I started spotting 1 week later and continued to have light bleeding for 2 more weeks although I was taking my pills as prescribed.

Delayed menstrual cycle by 10 days and shingles developed exactly two weeks after second shot injection.

After 1 week of first dose of moderna vaccine, patient experienced breakthrough bleeding and on and off spotting through out until she received the 2nd dose 28 days after.

The day after the second dose of the vaccine, I experienced breakthrough bleeding as if it was my period. It lasted 3 days and then abruptly stopped. I am currently breastfeeding so I have yet to get my period back since giving birth.

I have no reason to think this was caused by the vaccine but a lady from the CDC that called me asked me to file a report. I found out less than a week after my second vaccine dose that I was pregnant. At the time of the vaccine I was probably 3.5 weeks pregnant, but I didn't know yet. At my first pre-natal appointment, on 6/17/2021 I found out that I was having a miscarriage. The fetus had stopped growing about a week earlier at 7.5 weeks (around 6/10/2021) and had no heartbeat. There's no known cause for the miscarriage and I have not yet actually passed the fetus, so I'm still in the process of miscarrying. It was a missed miscarriage.

Extremely painful period. The worst pain I have ever felt. I almost fainted from the pain and I was sick a few times. This lasted for about 3 hours when my period first started. My period was one day late and the flow was normal.

Since the first vaccine shot I have not had my period. I have a Kyleena IUD, but I used to have 3 days of bleeding every month since 2018 when I got it. Now I do not bleed at all. I also don't get sore breasts or any monthly menstrual pains.

I got the shot on 4-21 and on may 2 i got a rash. The rash got worse the next day. Then stayed for a couple of days and went away. I take the birth control pill and it also made my period late and lighter and that is still continuing. After second shot i got a rash the day after the shot that lasted for a few days and went away. My period is still delayed and shorter/lighter

Missed miscarriage of 11 week old, mo/di identical twins. Discovered as lack of heartbeat on ultrasound on June 21.

Unaware of pregnancy status when she got her vaccine on 4/14 on 5/21 she had a miscarriage at 7-9 weeks of pregnancy.

After receiving the vaccine I had a menstrual cycle that was extremely heavy, painful and lasted about 38 days. I have since had another cycle that I am currently on day 36 of.

I missed my period the week after the vaccine, then came the following week after that. It was heavier than normal. I had it in the normally scheduled week of June, but my period was very heavier with lots of blood clots. It lasted seven days, but my periods usually last around four days and my periods are usually very light. I also had lots of spotting . I went to the OBGYN and they prescribed me a hormone to try to restart my cycle and get it back to normal.

Patient has been experiencing irregular menses since receiving her first vaccine dose. Prior to vaccination, patient has a 19-year history of regular menses occurring every 26-28 days for 5-6 days with no history of hormonal birth control.

My blood pressure started going up a week after my second dose. It was 180 over 104 for about a month and a half. Usually it was normal. I started my period on May 11th and it was super heavy, with really large clots. I had to go to the doctor for that. They are still monitoring my blood pressure. I am going back in August for a checkup, but I have had no more issues since that time

After the second dose of the Moderna vaccine for COVID 19, approximately 14 hours after at 5am, I experienced the "normal" signs and symptoms to start. I had fever, aches, chills, fatigue. However, when I walked to my kitchen, I became extremely dizzy, started seeing black spots, and my ears were ringing extremely loud. I thought I was going to pass out. A heat wave came over me, and I had an overwhelming feeling that I was going to throw up. I stripped my clothes off in a hurry to try to cool down and my vision became black. I laid on the kitchen floor for a few minutes and tried to go back to bed. I fell into the bed and began shaking and shivering. My husband was scared. By this time, my vision had returned. The ringing in my ears had reduced but was still present. I slept for over 15 hours and was extremely dizzy any time I got up to get water or use the restroom. By 4pm, I felt slightly better but for a full four days, I did not feel well enough to do anything. Since taking the vaccine, my periods have been different and I lose SO much hair.

Off-cycle menstruation. Period came 2 weeks early. Normally on cycle and very reliable, never had off cycle menstruation previously.

I visited my OBGYN that afternoon learned that I was approximately seven weeks pregnant, and that my baby was healthy with a heartbeat, I returned to the OBGYN four weeks later for my routine visit and leaned that the fetus had died around week 8, which was approximately one week after receiving the vaccine. I had no other issues or complications that would have contributed to my miscarriage.

My last period was Jan 7, 2021. Received Vaccine, dose 2 on 1/25/21 (I did not know I was pregnant at that time). Had a miscarriage and lost baby Feb 18-21

My cycle, which is consistent between 26-28 days, is now running into day 36. I have had PMS symptoms which are usually highly specific to me starting my period the next day on three separate occasions, with no cycle start. Two pregnancy tests are negative. I have also had period-like cramping. I wanted to pass along the information that I have not had any stress, change in diet, change in work schedule, sexual activities, or other change in routine or status.

The day of the injection I began with a headache and sore arm but for the most part was fine. Then around 7:00 pm that day I started to get the body aches and so I went to go lay down for bed. I started to shake uncontrollably, have horrible body aches and chills, I went from hot to cold to hot again all through the night, i had a fever all night long, bad stomach cramps, super nausea all night long, and bad headache. This last all the way into the following night having me miss a whole day of work because I couldn't get out of bed. Since this second shot I have had severe heart palpitations, prolong period, blurred vision and severe body aches.

I received my second Moderna vaccine on 3/8/21. On 3/10/21 I started spotting (bleeding: a menstrual period). This was 12 days ahead of my normal cycle. Today, 3/15/21 I am still experiencing mensuration bleeding. The blood is mostly brown, but also red, and has small clots. It comes and goes throughout the day unlike my normal period.

After the 2nd injection I waited 15min to make sure I am feeling ok. At that time I had no symptoms. As I was walking home walking home within 5min I had heavy bleeding, I wasn't suppose to get my period for another 2 weeks. The heavy bleeding lasted full 2 days, that day within 5hrs I had body aching and later had a fever. I had the fever and body aching for about 24hrs and my period for 2days. Since then I have been having random spotting of light or heavy bleeding. I had my period on 3-6-21 to 3-16-21 full days bleeding. Now I still have random spotting of blood cloth and heavy bleeding for few hours and it stops.

Reported and experienced common side effects: fever, body aches, soreness, and headache appeared within 24 hours of second dose. However, my menstrual cycle also occurred 1 week late. Also for the past 3 months since then, I have experienced spotting shortly before the onset of my cycle. I have been trying to conceive, and I am wondering if the vaccine has had an impact on my fertility. My menstrual cycle had always been regular prior to the second dose.

Began spotting on 3/29 continuing to today, 4/3. No history of spotting. No history of unusual periods. No history of pregnancy. Not currently pregnant. Spotting appears brown, sometimes red, and sometimes resembling mucus. Light flow requiring a panty liner. Last period ended 3/16.

After receiving the second Moderna vaccine, I (the patient), began light spotting/menstruating for 7 days before beginning my period, then bled (my period) for 5 more days. After 4 weeks, I started lightly bleeding again for 11 days, then began my period. I?ve bled 29/55 days. This is extremely unlike my body which usually bleeds 4-5 days/month, about 32 days apart.

I?m currently 11 weeks postpartum and exclusively breastfeeding my infant. I experienced typical vaccine adverse effects on day 0-1 (fatigue chills muscle aches weakness arm pain and fainting episode (I have a history of fainting and with other vaccines)) followed by mastitis on day 2 after my vaccine second dose. Mastitis symptoms included fever chills muscle aches weakness breast pain swelling redness and decreased milk production from blocked duct(s). I had no symptoms of blocked duct prior to the vaccine or prior to day 2. My prescriber ordered an antibiotic and ibuprofen which helped. We believe that the blocked ducts/mastitis occurred in relation to lymph node swelling that has been seen with the vaccine although we did not have a physical exam to determine if that is true.

After my first vaccine I noticed a few days I had some menstrual cramps. I didn't give much thought to it. However, after my second dose the cramps were so bad and I felt like my uterus was burning-- it was then I put together the correlation between the first shot and the cramps and the second shot and the terrible pain I felt.

2 weeks after receiving my first Moderna I experienced an alarmingly heavy period. It came a week early, in my 20 years of menstruating I?ve never experienced this heavy of a flow. I normally use light tampons and it?s rarely fully saturated after 6 hours, I was bleeding through supers within a few hours. There is a zero chance of pregnancy so it wasn?t a miscarriage.

Miscarriage at 25 weeks. No hx of pregnancy related issues. No hx of miscarriage. Reason for miscarriage not established/no clear reason for miscarriage.

Prior to my current miscarriage I had 3 pregnancy?s, 3 vaginal births (all pregnancy?s made it to term with healthy babies). My estimated due date for current pregnancy was 11/1/2021. I had an ultrasound at 8 weeks 0 days which was 3 weeks after my 2nd vaccine. The ultrasound showed a healthy heartbeat. 2.5 weeks later I had a second ultrasound that showed no heartbeat or movement. The baby measured at 8 weeks 4 days during the 10 week ultrasound. I have not delivered the miscarriage yet.

Change in Menstrual cycle, was not having any periods on IUD started having menstrual cycle again, increase in hot flashes.

I was diagnosed with placenta previa about 3 months ago. I had a bleeding event so I was hospitalized on the 27th. I was discharged on the 30th of March (3 days). I had another bleeding event on April 16 and I was discharged today (4 days). No medications added. Pregnancy history - I had a miscarriage in September 2020; this is my first full term pregnancy (getting there)- June 25th, 2021. I will still be on disability and not working for at least a few weeks.

Two days after my first shot I began to experience heavy bleeding. My period completed the Thursday before, so this was a 4 day gap (with no bleeding). I am a healthy mother of 3 with very regular periods, so this was extremely unusual. I also experienced cramping, fatigue and a taste of iron in my mouth.

One day after the first vaccine, my menstral cycle came a 5 days early. I thought it was odd but did not consider it further. 21 days later after my second vaccine, my cycle started two days after the vaccine, which is 8 days too early from the start of my last cycle and 15 days too early from normal.

Since receiving 2nd moderna vaccine, I have experienced irregular, painful periods and monthly reoccurrences of cold sores. I usually get 1, maybe cold sores each year x15 yrs but literally can?t get rid of them.

Missed miscarriage at 5 weeks gestation, I?m unsure if vaccine related it just happened around the same time. Due date was calculated Nov 3rd.

I have not had a normal period in about two months. I was very regular before this and I made sure I wasn?t pregnant but I am also using the Paraguard IUD.

Increased menstrual cramping - went from barely any to fairly severe after first injection and has continued after second injection. Still experiencing cramping today while on period.

More frequent and severe periods. I went from 35 days to 28 ish days. For the period starting 4/4/2021, I woke up in the middle of the night in severe pain, went to the ER and had tests run with the thinking that my appendix had ruptured or my ovary had twisted. My period started shortly after leaving the ER with no diagnosis. Period starting 5/4/2021 was very heavy at onset, one regular tampon per hour for 4 hours. Severe pain and cramps in front and back. Bloating. Despite not eating because of the pain I gained 12 lbs.

I am a recovering long covid patient (since March 2020). I improved greatly around December 2020. After the vaccine, my symptoms returned. Sinus tachycardia, brain fog, extreme fatigue, sleeping 20 hours a day, vomiting, diarrhea and constipation, SOB, joint and muscle pain, ocular changes. In addition, I started having terrible headaches, pain at injection site (left arm was virtually unusable for 3 weeks), and tinnitus. No menstruation since vaccination (2 confirmed negative pregnancy tests, and I was supposed to have my period right around the time I was vaccinated), intermittent uterine pain. Went to the ER and had 160 resting HR, and plan to go back on a beta blocker. Symptoms have waned somewhat, but I am still nowhere near where I was before the vaccine.

After receiving the 2nd shot of the Moderna Covid19 vaccine, I did not start my menstrual cycle on time. I have had a normal menstrual cycle for the past 19 years with no abnormalities. My menstrual cycle was supposed to start on April 14, but it did not start, and I had severe cramping and pain, bloating, and diarrhea for 14 days after April 14 when it should have started. During these two weeks I also gained 8 pounds, which is unusual for me. My menstrual cycle started 14 days late on April 28, and I continued to have severe cramping and also experienced heavy bleeding which is abnormal for me. My mentrual cycle is normally light and I don't usually have any cramps or pain.

Heavier than normal longer menstrual period with severe pain cramps. The night of first dose pain stiffness trouble walking next a fever 2 Days Later rash on my arm lasted 1 month. The site of the vaccine was swollen the size of baseball for 2 weeks. severe cramping like a menstrual period. After second dose period started early on the day of the vaccine 3/28/2021 with severe and heavy long menstrual period. Next month of April menstrual period late 4 days longer and heavier several pain. On 05/05/2021 ovulating with severe cramps pain.

At 10:30am, my period (which had ended Wednesday) restarted. I don't know if this is related to the vaccine, but it has never happened to me before. ARound 11:30am, I experienced a series of the most intense anxiety attacks I've ever had (I do have occasional anxiety attacks but not to this degree or duration), this went on for about an hour until I finally took half of a Xanax. My preferred methods of meditation, deep breathing exercises, and using essential oils didn't work, I haven't had to take a Xanax in over two years as these methods have prevented the need previously. It's been several hours and I still have a lingering sense of "doom" but haven't had another episode.

Late period (1 week) Period heavier than normal Period again 1 week later Spotting in between periods

24hrs after 1st dose, shortness of breath, hard to breathe, dry barking/bronchitis cough, sore throat, neck hurts, bad pelvic pain, lower abdominal pain,

Post vaccine I have not had a regular mensural cycle. The first cycle post the first vaccine was light and nearly clear. Then went to heavy and painful. I am tracking ovulation because I am trying to conceive and since the vaccines I have not reached peak ovulation. Regardless of what type of ovulation test I take my hormones never show there is a peak. My periods went from completely regular and ovulation very regularly, everything down to the same day or 1 day difference to now being sometimes a week off. This is without trying for the last 3 months due to irregularities post vaccine.

Moderna COVID?19 Vaccine EUA Have missed period that would have started April 29. I have confirmed I am not pregnant. I have never been off cycle or missed a period.

On May 6 I had the usual side effects - headache, sore arm, body aches. On May 12, I had a side effect that I had not heard of before - I got my period which is at a very unusual time of my cycle. I am on the birth control pill so my period is pretty regular and I would normally get it in about 2 weeks from now.

I have been on the DEPO shot for 4 years and have had no menstral cycle or symptoms. A month after I got the first vaccine and a week after, I started having light bleeding and cramps. It has been 4 years since I had experienced this. Now on today, May 15 - 2 months after my first dose of Moderna, I am having period symptoms again but with some stabbing pain in my uterus. I am very frustrated because these were NOT listed as side effects in the information given and I would not have gotten this vaccine had I known this would happen.

Two days after my second shot I started my menstrual bleeding violently and two weeks early. That night I woke in the middle of the night and my ears were ringing and my vision blacking at the edges and I was loosing a lot of blood. I started shaking so hard my teeth chattered, and was unable to get out of bed without feeling like I was going to pass out. My husband brought me juice and crackers, and it lessened within a half hour.

I had a miscarriage at 6 weeks pregnant. I have had 0 miscarriages in the past. I have 2 healthy children.

Extreme depression after vaccine Delayed period, spotty dark blood, very large blood clots and heavy cramping for over 3 days

Patient had swelling and tingling in lips and teeth. Unable to have normal bowel movement since vaccine. Cycle problems since administration. Patient reports being extremely tired for 5+ days. Unable to perform mcommon physical activities. Patient reports increased inhaler usage needed since vaccine. Patient used Benadryl for approximately 24 hours to resolve the swelling and tingling issues

Menstrual cycle was late - period was delayed by 28 days and had a period with more PMS symptoms than normal

severe stomach aches, severe period cramps and symptoms much worse related to PMS and period pain. two weeks after second shot, I had blurry vision for a day where I saw lots of white spots. for two weeks I had headaches as well.

I delivered a baby 12/28/2020, my period returned exactly 4 weeks postpartum and was regular after that, it came every 27-28 days. I got my vaccine 2/2/2021 while on my period and my period completely stopped the night after my second dose and returned two days later. Then 3 months after that (May 21, 2021), I was on day 13 of my cycle and I had a massive amount of bleeding out of no where. I took a pregnancy test to make sure there was no miscarriage and it was negative. I bled/spotted for another 3 days and it stopped.

Loss of pregnancy. I received my first dose at approximately 4 weeks pregnant on 3/30. I had a positive home pregnancy test the following day on 3/31. On 4.29, I had my first confirmation ultrasound where a heartbeat was found, but the fetus was not measuring as expected. On 4.30, I received my 2nd dose of the Moderna vaccine. A follow-up ultrasound was done on 4.12, at that time, no heartbeat was indicated and the fetus had stopped developing shortly after receiving the 2nd does on 4.30. This was my first pregnancy.

Late very light period, very abnormal. Negative pregnancy test. No treatment as of yet. Doctors appointment scheduled.

I became pregnant mid April 2021 after 3 uncomplicated pregnancies and suffered a miscarriage at approximately 10 weeks.

I was given the injection and immediately went to sit in the patient observation area for the required 15 minutes. I was feeling fine, made a quick phone call, and was just sitting and waiting. Then, 5 minutes after the injection, I noticed my arm at the injection site felt just the tiniest bit achy, but thought I was probably just imagining it. Then within several seconds of that observation, I could feel a blackout coming on--tunnel vision, ringing in my ears, general feeling of being unwell. I started to bend down to put my head between my knees, but that's the last thought I remember before waking up lying on the floor with the pharmacist tending to me. He said I had only been unconscious for several seconds. I was completely weak and still felt generally unwell. I also sustained a bump on my forehead and a hurt nose from hitting the floor when I collapsed. I recovered enough to walk out about 30 minutes later, and rested the rest of the day since the weakness lasted through the evening. I don't know if it was related or not, but I also started my period 4 days after that, which was 5 days earlier than expected, and it lasted a full 2 weeks (my period is typically 7-9 days).

Extreme heavy menstrual period. So far lasting more than 4 weeks. Previous periods have been normal. Blood tests normal. No fibroids/polyps. Doctors cannot figure out cause. Birth control not working to stop period.

After first Moderna vaccine had spotting and hotflashes. Three days after second moderna vaccine had vaginal bleeding for 21 days

The morning before my second Moderna vaccine I took a pregnancy test and it was inconclusive so I figured I wasn't pregnant and got my second vaccine (1/26/21). I missed my period and took another pregnancy test on 1/30/21 and it was positive. I went to my first ultrasound on 3/2/21 when I should have been around 8 or 9 weeks and the baby was measuring small but it had a heart beat that was in a normal range. A week later on 3/9/21 I started spotting and I called my doctor and they told me to let them know if it got worse. I went to work but by the end of my shift the bleeding had got worse and my doctor made me go to the ER so I could have another ultrasound. The ultra sound showed the baby still had a heart rate but it was low. I stayed home from work the next day to take it easy and I ended up having a miscarrage that night 3/10/21. I had a follow up ultrasound on 3/11/21 that proved it. I wasn't planning on reporting this because really anything could have caused it but I signed up for the vaccine app when I got my vaccines and answered the follow up questions. Someone called me because of how I answered my question and she recommended that I report it.

I had the vaccine on 01/20/2021 and in 03/12/2021 I went to the doctor for my 12 week check up and they said I probably miscarried 2 weeks before. I had a D&C. The delivery date would have been on September 20, other than that I have had a normal pregnancy.

I 'm on the 27 th day of my period. A lot lighter than I usually experience but not light enough to be considered spotting filling 2 regular sized tampons a day. Opposed to my usual periods having to change a regular tampon every hour or two. Also no usual cramps or back pain, no blood clots that I usually experience. in a lot of ways it's the easiest period I've ever had except for the fact that it is on day 27. I'm very tired all the time which is usual when on my period but not for 27 days.

Extreme itchy palms of hands and bottom of feet for 2 weeks. Prednisone was given and it finally went away. Onset of severe seasonal allergies and new onset of asthma. Was prescribed an inhaler which has helped my nightly coughing fits but I am still experiencing asthma symptoms which I never had before the vaccine. New lump in right breast. Mammogram scheduled for 6/23/21

Interrupted menstrual cycle- unusual hormonal changes not caused by pregnancy, menopause, other health conditions or stressors. First day of preceding period to first day of first period after vaccination was 50 days (patient?s average cycle lasts 28-32 days). Pre-menstrual symptoms leading up to first period after vaccination such as fatigue, body aches, breast tenderness, and mood swings were more intense and lasted for longer. Chose to ?wait and see;? period eventually started on it?s own, albeit much heavier than on average. I am unsure how else to report this information, so please forgive me if this is inappropriate: I contracted COVID-19 sometime in mid-January of 2021 and spent the last two weeks of the month quarantining at home. The illness itself was mild, the kind that during a typical cold and flu season you might call ?the sniffles? and carry on with normal activities. However, a similar, extended portion of time between the period before contracting COVID-19 and the one after occurred. Therefore, I am not filling this report to suggest a link between the Moderna vaccine and a ?late? period, but rather I?m reporting to suggest there may be a link between either COVID-19 or it?s affects on the immune system and a ?late? period. Other people who menstruate have mentioned similar effects via social media, so I know that I?m not the only one, even if this information is only anecdotal. I realize that COVID-19 and the vaccines against it are still very new to the medical world, but I feel that this is a topic worthy of further research and scrutiny.

Heavy period flow and severe acne on the face and neck. My period lasted twice a long. Acne lasted for several weeks. It was like going through puberty again.

Skipped May's normal menstruation date, then started spotting on 5/29/21. On 6/11/21 started a normal menstruation flow which lasted until 6/17/21. Then back to spotting 6/18/21-6/20/21. On 6/21/21 menstrual flow became heavy with a lot of clots and has continued until today on 6/23/21.

Late/no period, irregular PMS symptoms. Loss of appetite and weight. No desire to drink the amount of liquids normally consumed.

My periods got way worse after the first dose. Now I have cramps that two full days. Causing problems with work and school.

10 minutes after the injection my right arm was very heavy and tingle-y and my thumb throbbed. Almost 5 hours later, the sharp pain in my right arm has only intensified, though mostly concentrated about the injection site. 3.5 hours after the injection I felt a sharp pain radiate through my right hip to my inner right pelvic area. This sharp pain began pulsating, localized to the right inner pelvic area, nearly 6 times over the next 5 minutes and then dissipated. This same sensation was repeated about 1.5 hours later. That was when I decided to report my reaction thus far to the Moderna dose #1 COVID-19 vaccination.

I got my 2nd Moderna shot on 4/22/2021 and had unexplained spotting on 5/17/2021, about a week before I would later start my period. I saw my gynecologist and had a transvaginal ultrasound done and did not find anything concerning. My gynecologist believes menstrual irregularities is the result of my body falling ill after the 2nd Moderna shot. About 12 hours after the 2nd Moderna shot, I developed chills and a fever of 102.7 F. The fever lasted approx. 24 hours from onset. I took a Tylenol which helped (otherwise, the fever and chills could have been worse/longer). I also had headaches on and off until approx. 3rd day after the shot. The injection site was also swollen, blue/purple, and itchy (with symptoms peaking about 5 days after the shot).

Fever land fatigue lasting 5 days. Menstrual cycle 14 days late and menses times 14 days Asthma exacerbation

Began menses the morning of 12/23 prior to receiving vaccine. Had my vaccine and menses became unusually heavy, with more cramps than usual lasting a full 8 days when normally my cycle is 2-3 days total. This has never happened to me before. Also, had headaches daily (frontal, ache) for 4 days beginning on day two or three.

I was experiencing what I understand to be one of the more common side effects: pain at injection site. This pain kind of traveled to other parts of my arm and eventually my arm pit. I noticed the pain travelling around the date of 1/2/2021, and by 1/6/2021 it getting more intense. As I was trying to massage out the soreness, I noticed a palpable, painful lump in my right breast. I did not immediately recognize it as a swollen lymph node at that time, but after several Dr exams, and the lump and pain decreasing, I believe that is what was happening. I do still have the lump, and it is tender, so I am currently monitoring it.

Approx 10 days after vaccine a red, raised rash appeared around injection site. Area was swollen, painful, warm, and itching. The rash continued to spread and almost completely wrapped around the entire arm. She also experienced heavy vaginal bleeding, and was not due to begin cycle. Last cycle ended 1/5 and bleeding began on 1/23, and she also experienced abdominal pain on 1/25. When rash was at its worst, she was extremely fatigued.

Lymph edema started 3 days post injection. Started under arms. Day 4 it moved to left breast. Day 5 the swelling continued to left lower abdomen area and left labia. Skin is very tender to the touch in swollen areas

I have the Nexplanon birth control implant in my left upper inner arm. I rarely get my monthly period and since I received the vaccine I have had vaginal bleeding for the past 17 days. My entire left arm is still very painful and very weak.

I was 5 weeks 5 days pregnant with a EDD of 9/17/2021 at the time of my 2?d covid19 vaccine on 1/20/21. On 2/8/21 I found out that my fetus stopped growing at 6w1d, documented on US without heartbeat in the ER. I had a spontaneous miscarriage on 2/9/21.

Started with arm pain about half an hour after shot similar to first shot but more immediate. Later around 5pm I started to experience full body aches akin to the flu. Then I had chills and a mild fever of 100 and a headache. This lasted through the night. I slept until 11am today the 11th and awoke with only a headache. Then around 8pm I began experiencing menstrual cramps and breast tenderness despite my cycle (bleeding) ending 5 days ago. I usually do not experience menstrual cramps. This has been happening for the last 2 hours. It?s now 10pm

Breastfeeding and 7 months postpartum I?d had no sign of a period retuning. For two days after the first dose I had intense uterine cramping (already reported) and then today, two weeks later, began a VERY heavy period. Heavier than I can remember having ever before.

shortness of breath, pelvic pain, joint pain, right hand paresthesias, axillary pain (R), fatigue, GERD

Miscarriage; Received vaccine when pregnant; A spontaneous report was received from a 34-year old female patient who received Moderna's COVID-19 Vaccine (mRNA-1273) when pregnant and experienced a miscarriage. The patient's medical history included three prior pregnancies, with two live births and one miscarriage. Products known to have been used by the patient, within two weeks prior to the event, included prenatal vitamins and doxylamine succinate/pyridoxine hydrochloride. The patient received their first of two planned doses of mRNA-1273 (Batch number: 011J20A) on 30 Dec 2020. On 27 Jan 2021, the patient received their second of two planned doses of mRNA-1273 (Batch number: 028L20A) intramuscularly for prophylaxis of COVID-19 infection. At 7 weeks gestation, the fetus had a normal heart beat. She reported that she had no complications with the pregnancy. On 08 Feb 2021, the patient had a miscarriage. Treatment information was not provided. The patient received both scheduled doses of mRNA-1273; therefore, action taken with the drug in response to the event is not applicable. The events received vaccine when pregnant and miscarriage were considered recovered.; Reporter's Comments: This report concerns a 34-year-old, P2G4 who experienced miscarriage 1 month 9 days post administration of first dose and 12 days after the last dose of mRNA-1273 vaccine. There is not enough information such as the last menstrual period, estimated date of conception and delivery and gestational age at the time of miscarriage. In addition, the patient's detailed medical history including any trauma and reason for previous miscarriage is lacking. Vaccine exposure during pregnancy is assessed as not applicable.

Irregular menstrual bleeding began almost immediately after receiving first dose of vaccine. This is a highly uncommon incident for me as I just completed my menstrual 2 weeks ago and it never comes early nor do I experience break through bleeding.

I experienced a miscarriage on February 27th, 2021. I was approximately 10 weeks pregnant when I experienced the miscarriage. It was accompanied by severe pain/cramps in the abdomen and lower back. Expected delivery would have been in September 2021. This was my first pregnancy.

After my second dose I had a miscarriage but it was identified on 02/22/2021, I was 11 weeks pregnant and I had no complications with my pregnancy, Before my 1st dose my platelet blood count was at 400 then after my 1st dose it went to 538.

I had an IUI performed my my OB on 2/1/2021 and received the 2nd dose of the COVID vaccine on 2/4/2021. I found out I was pregnant on 2/15/2021 and found out I was miscarrying on 2/26/2021.

I received the first dose of the vaccine on 1/31/21. I was 33 weeks pregnant, with an estimated due date on 3/21/21. This was my first pregnancy and I had no complications up to that point. On 2/2/21 I began experiencing menstrual type cramps, which continued for a few days. On 2/5/21, my OBGYN suggested I be examined in Labor and Delivery, where it was determined I was in pre-term labor. Contractions were temporarily stopped, however my water broke on 2/7/21 and it was suggested that I be induced. I was induced on a later date at 34w1d pregnant and delivered my son, who weighed in at 4lbs. 15oz.

After my second vaccine, and few weeks later, I suffered a miscarriage on 02-18-2021. I went to see my OBGYN who performed an ultrasound. My baby at that time was 6 weeks old.

I take Depo-Provera and have been for multiple years which has resulted in no menstrual cycle in YEARS. Two days after receiving my second COVID shot I started bleeding/spotting EVERY SINGLE day for 6 weeks. It finally just stopped.

1: the day after my first covid shot, in the evening, my heart rate jumped from around 70 to around 130 instantly when walking up the stairs in my house. This happened twice that evening and has never happened before. My pulse was pounding in my head and it took about 1-2 minutes of slow breathing to calm my heart rate again. I wore my heart rate monitor the rest of the evening and overnight, with no other adverse effects. Stairs had no impact on me the next day. I had also exercised that morning, and while my heart rate was higher than normal with that type of workout, I didn?t think anything of it at the time and didn?t have the pounding head issue. Due to this issue, I?m a bit nervous about the second shot in the series. 2: I started my period the morning I got the shot; day 4 and 5 of my period were significantly heavier flow than normal. Day 4 also included cramps and nausea throughout the entire day, which is not normal for me.

Very early menstruation for 2 (all) cycles following vaccination. Ex: normal cycle is 28 days. Now cycle is 19-20 days.

In the early afternoon of 3/25 I noticed pain in my breast while nursing my baby. After the feeding I could feel a hard lump on the underside of my breast that was tender to the touch and warm. I used an ice pack on the area, took curcumin and grapefruit seed extract, and nursed again on our regular schedule. The clog was resolved after the next feeding and after taking the supplements and using ice. Clogged ducts have happened to me frequently in the last ten months of nursing. I don?t know if this was related to the vaccine, but I figured I would report it in case it became a pattern in nursing mothers.

No real symptoms at time of vaccine. Pain after injection for two days. Pain in right hip for five days. Went in for ultrasound on 4/1/21 at 9 weeks 4 days and found out that there was no fetal pole. Measured at 8 weeks 3 days with gestational sac and yolk sac but no embryo. Considered an embryonic pregnancy, empty sac, or blighted ovum Approximate loss 3/24/21. Still waiting to pass tissue to fully miscarry.

Fever, headache, muscle pain, weakness, chills, dehydration, triggered menstruation a week early.

I had no acute immediate reaction that was not typical, but after 2/3 days I felt hot and cold for about 4-5 days but no actual fever or tachycardia. Then noticed that I had a significant delay in my menstrual cycle that was very abnormal for me. I was suppose to start my regular cycle 6 days after vaccination. I am very regular and my menses were delayed by two weeks. In addition, when it came back there was a change in my flow (very short duration). I am concerned about possible implications of the vaccine regarding my menses.

HIVES, EDEMA, HEAT, SWELLING AND REDNESS AT INJECTION SITE. STARTED MENSTRUAL CYLCLE 2 WEEKS EARLY AND IT WAS VERY HEAVY AND LASTED ABOUT 10 DAYS.

Swollen lymph nodes in center of left armpit (same side that I was vaccinated on), painful to the touch and when I move my arm up and down Some breast tenderness/pain (weird feeling) on the same side (left) A bit of tiredness/fatigue

I have a history of heavy periods which resulted in the need for an ablation in October 2018. Since the ablation my periods have been much more manageable. I got my period 13 days after receiving the shot and it started out much heavier than normal, by the second day I was bleeding extremely heavily, soaking an overnight pad in less than 2 hours with bright red blood and passing clots the size of dimes and pennies. Day 3 has started out the same as day 2. Prior to my period starting my back hurt and I had much worse than normal abdominal cramps. Nothing in my life has changed besides the vaccine, I am certain there is a connection between the two. I am not sure how long this will last, I was instructed to go ahead an report the adverse event.

Significant increase in depressive and anxiety symptoms. Menstrual cycle is also a week and counting late

One week after the first dose of the vaccine I had breakthrough bleeding. It was enough to soak a sanitary pad. I went to the ER and they could not identify the reason for the vaginal bleeding. I was discharged the same night. It reoccurred three days after when I had been on a walk. It did not happen again and I did not have any problems after the second shot. The baby seems to be fine. Due Date -09/17/2021 Pregnancy-First

Spotting (light bleeding) for 3 days turned into shedding huge blood clots vaginally from 4/3 - 4/5. I bled though pads in just 5-10 minutes. Clots ranged from the size of a quarter to the size of the palm of my hand. They were very large, very frequent, and very painful. I never experienced this before in my life. The bleeding lasted 12 days total.

I found out that I was pregnant four weeks after the second dose. I started to itch all over my body four weeks after the shot. I did not have a visible rash, but my dermatologist said it was a histamine reaction. I was intensely itchy for three days and then it went away after five days. I had a miscarriage five weeks after the second dose which was a week after the itch started. I saw my OBGYN, PCP ER , Gastroenterologist and Dermatologist. Due Date: 12/11/2021 Pregnancy Third Pregnancy

2 days after the second shot I got a VERY heavy maturation, within the next coming weeks I had it 3 times in under 30 days (the last one beginning on April 10). Each lasted over a week.

Received the vaccine on the 3rd and 31st of March. Got my period on the 2nd of April and now I am having it again on the 24th. Unsure if related by I have had Normal periods for 20 years and the only thing changed is getting the vaccine.

Irregular bleeding; believe to be menstrual cycle starting 1-1.5 weeks before period should start. Heavy bleeding!

I got the moderna vaccine on 02/23/2021 1st dose. My LMP was 02/03/2021. On 3/5/2021, I took a pregnancy test due to nausea and it was positive. I was super concerned due to getting the covid vaccine around the time of ovulation and so I contacted my FNP and started getting serial Hcgs due to right side pelvic pain which was confirmed to be a hemorrhagic corpus luteal cyst. A couple of weeks later, My 4th Pregnancy was confirmed via trans vaginal ultrasound with a strong heart beat on 03/30/2021 and a gestational age of 7 weeks exactly and a due date of 11/16/2021. I decided not to get the 2nd dose of the vaccination due to concerns of miscarrying in the first trimester and limited studies on covid vaccine and it?s safety despite having 3 healthy children and zero miscarriages in the past. On to my next appt on 04/19/2021, the fetus should alreayd measure at 10 weeks. Without having any abdominal pain, bleeding, or spotting, the baby stopped growing and measured at 7 weeks and 5 days with no heartbeat. Again, I had no symptoms of miscarrying at all. We decided for a d&c and sent the fetal tissue for genetic testing. My d&c was performed on 04/22/2021 at 12pm. We are currently waiting for genetic testing results at this time.

I should have gotten my period for my menstrual cycle staying a day or two after the vaccine, but now 7 days later I have not gotten my period and I have a negative pregnancy test. I have never missed my period with the expedition of the pregnancies. I'm never late on my period but sometimes am early. This is not typical for me and I am meticulous on charting my menstrual cycles.

My menstrual cycle this time is 58 days. At the same time, there was a lot of menstrual blood today, and four-quarter-sized blood clots continued to flow out.

I received the 2nd shot Friday, 4/23 at 10:05am. I had previously started my period cycle on Thursday, 4/22 (the day before). By Friday between 3-4pm I had completely stopped bleeding. I continued up until present day with no menstruation bleeding or spotting at all. I have taken pregnancy test on Monday, 4/26 that was negative. This is VERY unusual for me and my monthly cycle. I track every symptom, every sign, etc. leading up to my cycle each month. I know exactly when my body ovulates and when my body will start the cycle over again. This has never happened before.

Menstrual bleeding 2 days after second COVID shot, have not had a menstrual cycle for last 5 years due to IUD.

Increased heavy menses with debilitating cramping pain. Took 2 Advil liquid gel 200mgs to help with pain. About 2 hours later I felt better. Pain continued for a total of 2 days.

Pt develop heavy vaginal bleeding with clots 5 days after receiving the shot. Bleeding was heavy enough to drop her hemoglobin and require an emergency D&C.

Menstrual cycle began 2 weeks early (first cycle after 2nd dose). Unknown at this time if it's a permanent cycle change

Patient developed spotting within 3-4 hours of vaccine administration, and miscarried approximately 24 hours later. Patient was about 7 weeks pregnant at the time of vaccination.

Vaginal blood hemorrhaging started at 4am. Admitted to ER. Severe bleeding and passing of large blood clots. Required an emergency D&C and a blood transfusion, plus fluids.

Menstrual cycle began 10 days early, 7 days (to the hour) after my 2nd vaccine dose. Period lasted 9 days, when 4-5 is normal.

For the next three days, I got pretty sick. Low grade fever - around 100. If I took a Tylenol it would go away for a little bit but then come back. Pain in my arm. Nausea and major, major, major migraines. I had migraines consistently - couldn't move off my couch. Those symptoms mostly went away after the third day. I saw my OB/GYN this week and they said that my fetus stopped growing about three weeks ago. Pregnancy history - my third pregnancy; none have gone to full-term. I have had a miscarriage before that was very similar to this one. Estimated date of delivery - December 2, 2021. I have recovered from the immediate side effects. I get the fetus removed next week.

Miscarriage Got my first Moderna shot on 04/03/2021, second Moderna shot on 05/05/2021. Cramping on April 26, 2021 as I was 5 weeks pregnant, bleeding on 05/06/2021 confirming miscarriage. Last period was 03/25/2021, due date was planned 12/30/2021.

No previous history of Miscarriage, one successful pregnancy. The estimated date of delivery was November 3rd, 2021. Miscarried 1 week after first covid vaccine. Ultrasound with strong heartbeat completed 4 days prior to Moderna vaccine.

Customer experienced numbness that started about a half-hour when she arrived home. Then 5-6 days later, she felt an enlarged lymph node by left axillary and pain in that area. She felt more painful at night. Also, if she ate spicy food, more numbness. When she stopped, numbness left (or numbness lessened). She missed her period for 1 month. She was suppose to get her period around her vaccine day, but she still did not receive her period. She thought she was pregnant, and checked with her doctor's office. Not pregnant.

Mild hives and itching on chest and injection site. Weakness, pain and muscle spasms in thighs, hips/pelvis. Lasted 2 days. Heart racing.

I received my 2nd vaccine and My period came 5 days early and I am bleeding heavy and clotting quarter size clots. Started about 8:30pm on 5/13/2021.

First it started with the arm pain, then a headache, internal fever, chills and a lot of pain throughout the body, mainly the pain in my back and my lower back. Through the area of ??the kidneys and the pelvis. The intense pain lasted about midnight, I took a pill of TYLENOL for pain and to be able to sleep, which helped me a bit but the next day the body and back pain persisted ... what hurt the most was my lower back and I could not bear to lie down in any way so I remained semi-lying or sitting in bed because when I lay down my back bothered me. I took natural teas to help me and I took water and electrolytes to feel better. gradually by the end of the second day my pain symptoms were decreasing. The dizziness in the head remained very persistent on the 2nd day. On the third day I felt a relief from my muscle pain but the discomfort or dizziness of the head was still there, it was not as strong as the last days, but when moving my head from side to side or sitting or standing up it was like a vertigo or a unstable that I felt was there. By the 4th day I felt better almost no symptoms just like body sweat ... like hot flashes.

3 days post vaccine, noticed pain in left armpit area 2 weeks post vaccine, noticed palpable cord in the breast, tenderness with arm movement and palptation

Severe fever and chills for 36 hrs; followed by severe menstrual pain and cramping for 12 hrs (so far)

Moderate swelling of neck causing hoarseness, tenderness, and loss of voice lasting approximately 2 days. Slight swelling, pain, and redness of injection site that currently persists. Early onset (7 days) of menstruation with sudden heavy bleeding. Low-grade fever, nausea, fatigue, muscle aches, weakness, and generally not feeling well for approximately 4 days.

while I had the typical vaccine symptoms after my second dose - my menstrual cycle was different from normal with more intense PMS and heavier flow. I typically feel PMS like cramps. bloat, diarrhea, heavy flow with thick dark blood and moodiness for 1-2 days. After my second dose, I noticed I had the same PMS but each symptom felt much more intense and lasted for 3-4 days. The length of days of my cycle was not affected and it started when expected.

My period ended 2 days before I received the first dose. Within 24 hours my period was back and heavier than it has ever been, with multiple dime size clots. It lasted at the same heavy flow for 8 days, while a normal period for me is incredibly light (only needing a pantyliner) and typically lasting 3-4 days.

Fatigue and pain in left arm continues 3 months post vaccination. Chronic menstrual clots larger than a golf ball.

Vaginal bleeding, cramps and headaches as of 5/13/2021 to present day. Period cycle was prior to vaccination and only last 3 days.

Menstrual cycle started after the first dose of Moderna. Continued through the entire next month (daily). Received the second dose and the cycle continued daily with heavy bleeding and enormous blood clots. Lasted 10 weeks. Stopped for 3 weeks. Started again and currently on day 16 of continuous menstrual cycle. Blood clots were as large as my palm with excessive cramping occurring. Using tampons made the clot presence and intensity worse too. Fainted twice in my bathroom after passing blood clots. Sometimes the blood clots fall into the toilet and sound like marbles hitting the water. The largest blood clot had smooth borders, could not be pulled apart, and was the size of my palm.

Very heavy menstrual cycle after second COVID shot. My menstrual cycle also last a few days longer than it usually does.

One week after the first shot I started having abnormal vaginal spotting. I have not had a period since before getting the first dose. I noticed extreme thirst hours after getting both doses that lasted about 24 hours.

Menstrual Cycle changes. More severe cramping and bloating. Much lighter and irregular cycle yet more painful. Almost zero blood.

Within 12 hours of receiving the second vaccine, I experienced flu-like symptoms (nausea, headache, body aches). They dissipated somewhat with Tylenol, but lasted roughly 48 hours. Additionally, since the first Moderna shot, I have had breakthrough menstrual bleeding. This is unusual given that I am taking oral birth control. The bleeding began roughly 10 days after the first shot, then I had a heavy menstrual cycle, and then the breakthrough bleeding began again roughly 10 days after my second shot. I called my OB/GYN about this, but they said their data was too limited to advise me on how long this is expected to last.

Vaccine was received during the second day of period cycle, vaccine resulted in an abrupt end to menses. Following cycle was half as long as normal, occuring again in 23 days instead of 42 (as is normal for patient).

I believe I was very early on in my pregnancy (as in, implantation or first week after conception) when I received the second dose of the vaccine. EDD was January 9th, 2022. I had brown spotting every day for the duration of my pregnancy, obviously concerning and something I paid attention to (though not altogether unusual in early pregnancy). I ended up miscarrying naturally at 6 weeks. I am strongly in favor and appreciative of this vaccine and would be surprised if there was a direct link, but I do know there is a growing conversation about its impact on women's menstrual cycles. I wanted to submit my experience just in case it was in fact a trend for other trying-to-conceive or early pregnant females.

I was pregnant when I got my second shot (due date (1/2/2022). I subsequently had a pregnancy loss that started on 5/19/2021.

I believe the Moderna vaccine triggered my body to have a second period in the month of April. I have recorded my periods over the past year because of my POTS. I had my period on April 2nd and it ended on the 10th. Four days after the shot, I had the shot on April 26th, I got my period for a 2nd time 19 days after my period just ended. The 2nd period ended on May 6th. I have yet to recieve my period. Medication, stress levels and diet haven't changed for me so those weren't the trigger.

Heavy painful period... abnormal timing and extremely heavy. Cramps were so bad that I would be screaming in pain.

Irregular menstrual cycle symptoms. From typical 5 day predictable monthly cycle to 12 days of fresh bleeding and more intense symptoms from what patient was used to experiencing: soreness and swollen glands in neck, sides, swelling in hands and feet, body aches and pains, cramps, headaches, poor concentration, and depression-like thought patterns, as well as the notable fresh blood for 12 days straight. The timing has also been irregular and unpredictable each month since. Longer PMS windows as well.

immediately after the vaccine my arm and hand were itchy and hot. later that night i had normal cold symptoms which i expected. everyday after that i have experienced severe headaches. i wake up everyday with a pounding headache. my arm is still sore. Most concerning is the fact that i have started menstrating again. i have and IUD and havent bleed in 6 months. now iam. my glands are swollen under my jaw as well. These symptoms are still current 7 days after the vaccine.

Imediately after the injection i had itching in my left hand for 2 hours. I was very sick for the net week which i expected with chills a fever and cold symptoms. The thing im concerened about is that i have started menstrauting. I havent menstrauted in 6 months due to an IUD. Now its been almost two week and my shoulder is still hurting.

Menstruation cycle abnormal since second dose of Moderna vaccine. Since February, cycles have been heavier and cramps more painful. Menstruation time period is normal (5-7 days), breast tenderness/enlargement worse than before. Heavy days have increased. Cramps will wake me up in the middle of the night. Nausea and hot flashes also occur now. Cannot exercise/run during cycle due to cramps becoming so severe I'm doubled over in pain until it subsides. Ibuprofen continues to help, though it feels like I take more than usual. This will be cycle number 4 post Moderna vaccine where periods have been noticeably different than before.

I started having SOB on standing and it has not subsided. No PMHx of asthma, COPD. Menstrual cycle has changed?starts 5 days early and is thick and brown colored at the beginning. I am on ortho tricyclen. Developed left supraclavicular lymphadenopathy that lasted 10 days. I was very concerned about this, as I have never had one before and have no history of TB and no cancer that I know of.

started a menstrual cycle a few days later than usual, had significant loss of blood on the 8th day, which turned out to be a spontaneous miscarriage and not a menstrual cycle, tested through blood test.

I have had an irregular period since my second shot. They have been every 3 weeks and last longer. I have also have had a unusual amount of spotting.

I have been tracking my menstrual/ovulation for years now and am alway have very regular ovulation between days 12-15, and a 24-27 day cycle. The cycle I got my second Moderna shot I had my first anovulatory cycle that I am aware of in my life, and my cycle was 45 days long.

After my second dose on 5/19, I was supposed to start my period on 6/9, and it did not start until a week later on 6/16. I am extremely regular and the only times I?ve ever been a week late were when I was pregnant. I knew I was not pregnant as I have my tubes tied. So it started late, then I bled for 2 weeks, which has never happened in my entire life. If it didn?t stop bleeding, I was going to make an appointment with my Gyno. I had no life changes, diet changes, or added life stressors during this time, so the only thing I can deduce is that the period changes were caused by the vaccine. It has seemed to end, but I don?t know when my next period will be, or how long it?s going to last. I?ll have to wait and see next month.

Pregnant at the time of vaccination, 8 weeks. Very first ever pregnancy, no history of miscarriage or abortion. Heartbeat detected via ultrasound 36 hours prior to shot on 6-28-21 at OBGYN appointment. Covid shot taken on Wednesday 7-1-21, Miscarriage occured on 7-3-21. Confirmed loss of pregnancy via ER visit due to bleeding and cramps from ultrasound. Please do more research for 1st trimester before clearing pregnant women as safe to take COVID-19 vaccination. Please add my information to any existing data regarding 1st trimester loss of pregnancy.

Extremely heavy menstrual period. Period is on time but I am soaking completely through a regular use tampon in ~3-4 hours when one would usually last me 6-8 hours.

NEVER HAD AN IRREGULAR CYCLE THE MANTH AFTER VACCINE BEGAN A 5 WEEK CYCLE DOCTOR PLACED ON BIRTH CONTROL TO REGULATE BLEEDING.

My two periods after each dose were heavier than normal. My third period that came a month after my second injection was 2 days late and extremely light. Late and almost not existent menstrual cycle isn?t common for me at all.

No menstrual cycle since vaccine 12/28/20. It has been 224 days with no period. I have never gone this long with no period and typically have a cycle between 30-40 days.

Breast tenderness and vaginal bleeding. Bleeding was light and lasted about two weeks. I didn?t think much of it until I got my second shot and I started bleeding again the same day. The breast tenderness was worse after the second shot than the first, I will file a separate report for the second shot.

I was vaccinated for my 2nd dose of Moderna Vaccine on 5/4/21. We have been trying to get pregnant for months and I found out on 5/14/21 that I was pregnant. Confirmed with a hcg blood test at the urgent care on 5/15/21. Monday 5/17/21 at around noon, I just started spotting and went to MD right away. He ordered bedrest for the whole week but my bleeding didnt stopped and led to miscarriage.

got pregnant in February after the second dose and in April the doctor said the baby didn't have any heart beat and may i had the surgery and miscarriage.

I am of child bearing age. The vaccine brochure did not state that I could get spotting but I started getting spotting after 3 days. Other than that I am fine. Just had minor achy arm at the injection site. I just wonder if other woman are experience this? And if this will affect my fertility?

Patient developed swelling from the left breast to the anterior aspect of the neck with anterior lymphadenopathy. Patient received 8 mg of Decadron IM on 2/2/21.

I took an at-home pregnancy test on 1/26/21 and 1/27/21 after a missed period of which both were positive. On Saturday 1/30/21, I began to have heavy bleeding of which lasted through the weekend. I also experienced cramping and low back pain. On 2/1/21 I had an Hcg lab value of 3.5 confirming I had miscarried. This has lasted through 2/2/21.

Headache and chills about 12 hrs after the shot, L arm soreness about 3 hrs after, HA and chills resolved within 36 hrs. Vaginal bleeding/spotting occurring about 48 hrs after and is currently still happening. Menstrual cycle is not due for another 1.5 weeks.

Symptoms started after almost 24 hours. Severe chills, throbbing headache, joint pains, sweating, extremely tender boobs ( nursing mom ) symptoms still going on after 72 hours of vaccine administered. Taking tylenol

at 2am I woke up with fever, chills, headache, and nausea. I took tylenol and it improved. I slept on and off. When I got up the next morning at 6am, I realized I had mastitis on my right breast ( I got the vaccine in my left arm.) The mastitis consisted of redness around the areola, pain, swelling, and my lymph node in my right armpit felt slightly enlarged and painful. My fever was 100.9

At approximately 1:06pm I felt lightheaded, nauseated, with a light headache, mild tightness in my chest, I felt extremely tired, along with mild pain in the left side of my body ( left side of breast, shoulder ,arm socket, elbow, wrist , fingers, hip, knee, ankle, top of foot and toes). 3/6 Headache increased, tightness in chest mild, left joint pain mild (left side of breast, shoulder ,arm socket, elbow, wrist , fingers, hip, knee, ankle, top of foot and toes).Feeling extremely tired .3/7 Headache persist, tightness in chest still bothersome, left joint pain( entire left breast in pain, shoulder ,arm socket, elbow, wrist , fingers, hip, knee, ankle, top of foot and toes, tightness on side of breast ) increased with noticeable swelling, at times shortness of breath, some pain in chest when taking breaths.

Initially tasted metal, numb mouth, flushing, later resulting in all flu like symptoms (severe chilling, fever, body aches, headaches and GI issues.) GI issues persisted for the next 3 weeks and on Thursday evening, 2/25/2021 at about 6:30 pm. I was sitting on floor with children and almost passed out. I felt very faint, dizzy, and instantly started chilling. I had a fever of 102.8 and could not get warm. My husband was going to call paramedics, but I encouraged him not to. Discovered my right breast was red and inflamed/ swollen as well as all of my lymph nodes in my right arm pit. I could not reach my right arm forward. I noticed around 12:06 AM after not being able to get warm or break fever. I messaged my primary care clinic when I noticed the breast swelling, redness, pain, and lymph node swelling. I continually felt like I was going to faint/pass out and was very dizzy all night long. I was also extremely fatigued. The did a telemedicine appointment the next morning and diagnosed me with mastitis and prescribed me antibiotics. I am a breastfeeding mother and all of these symptoms came on suddenly and severely on the same side that I got the vaccine shot. I have been breastfeeding for over 7 months and my supply has been dwindling to nothing so I have no problems with engorgement or blocked milk ducts. Before this baby I had just got done breastfeeding a baby for 11 months with no issues of the like.

Sweating, low-grade fever, chills, body aches, exhaustion, headache. I took Tylenol for 24 hours starting when I woke up at 6am to help with symptoms. It took about 36 hours for my symptoms to be gone after they started. I was also on my period when I received the vaccine. My period seemed to slow down almost completely while my symptoms were happening, and then my period resumed with abnormal cramping and clotting after my symptoms were gone.

Started bleeding the 17th, went to the doctor OB/GYN office and had an Ultrasound - I was supposed to be measuring at 8 weeks and I was measuring at 6 weeks. Miscarried. My due date 9/26/2021 would have been due date; That was my fifth pregnancy. That was my 3rd miscarriage. I have had two full term vaginal deliveries.

Completely saturated overnight pads at a rate of about 1 per hour. Began at 7pm. Had never had bleeding like this before with other cycles.

Headache has continued this entire time.

My period was scheduled to start approximately 2 days after the vaccine and my periods never happened. I went 72 days with no period. I have never had irregular periods and no other lifestyle changes or stressors occurred to affect my period.

Arm became swollen, lymph node under are and breast tissue was enlarged. This began the day of the vaccination. Mouth sores on tongue began the 5th. painful tongue blisters, loss of taste. This continued for over a week. Tongue blisters are still present, but healing. Tasted has returned. Circulation issues began, fingers and toes going numb and turning white has continued since event.

Large slightly raised rash about 2" below injection site, only moderate relief from over-the-counter anti-itch cream. Heavy breakthrough bleeding while on active pills for birth control.

Severe period cramps which I haven't had in months since I've gotten COVID-19 back on Jan 29th. I believe I got it then bc I wrote on Feb 14 exactly 2 weeks after seeing our factory partners. My head felt shaken like astigmatism in my brain. So haven't had a real period for a year and then after the vaccine worst cramps in my life. Then I have stomach hurting and GI issues every hour or so. Lastly my eyes have been red at night a lot and I would keep getting headaches from time to time for no reason and I'm not a headache person.

2 prior first trimester miscarriages unrelated. 1 second trimester miscarriage at 21weeks gestation in March 2021, normal weight and size at time of delivery. Vaccine was given 12/2020 and 1/2021

I had an instant reaction. With in mins of sitting after vaccine. I starting feeling hot, and very itchy on my right arm (site). I then noticed I was very red, and itching more and more, around the same time. The nurse had looked over at me that gave vaccine and said you look very red and "are those hives" I had hives on my chest, arms, back, butt, and you could see the red rash/hives visually spreading. Roof of mouth also was itchy. They gave me 2 benadryl and water, asked me to stay and be observed for a half hour or so. I started feeling relief soon after benadryl. But, not full relief until much later that night. I also Had very painful and swollen lymph nodes at injection site, through my right breast and neck. for 3 wks or more. they might still be slightly swollen, but no more pain. Very scary. I had Covid back in November, I had symptoms of not being able to control my body temp since./ After I received vaccine, I aslo developed covid toes for a few wks and now my feet get very cold and purple almost black from just the slightest cold.

Very sore and tender breast, rash in the injection site, fatigue, headache, pain/discomfort underarms and side of breasts, swelling in arm. Injection site is hard and warm.

A little over 12 hours after I received the first dose I woke up with the worst cramps I?ve ever had in my life then started my menstrual cycle four days early. It?s extremely heavy which is not normal, nor is the intense abdomen pain I felt after the shot.

I had a miscarriage (spontaneous abortion) on March 14, 2021. I was 12 weeks pregnant at the time of miscarriage.

Associate received the vaccine and experienced exacerbated symptoms related to her IBD and arthritis for 5 days as well as a change in their menstrual cycle. The associate also stated that her menstrual period, "came earlier than expected and the amount of bleeding was abnormal" to the associate. She also stated that her arthritic pain was severe and she had an increase in diarrhea that was abnormal to her chronic conditions. All of these lasted 5 days. Associate had to stay home from work and self managed her symptoms.

Very sore at injection site immediately after shot. Left arm was very sore 3/31/21 through 4/2/21. Patient was very fatigued on 3/31/21. Menstrual cycle began as expected on 4/6/21 and is much heavier than normal, with unusual and painful cramping. Low fever (100F) and fatigue, along with heavier than normal bleeding continued 4/7/21.

The day of the shot I had some pain on my right side body, right jaw... on Wednesday I was just very tired and slept a lot. Thursday morning I woke with pain in my hips and Pelvis, and around 9am pelvic pain started that felt as sever as the pain I felt giving birth (20 months ago). Thurs/Friday and today (Saturday) it?s been so painful I?ve had a hard time walking, laughing, coughing and caring for my toddler has been immensely challenging. My period began Friday afternoon, a heavier flow than usual. To be clear I have VERY mild periods and am a very healthy young woman. This is unlike anything I?ve ever experienced and the only thing that is different was receiving the vaccine and upon further research it seems MANY women of menstruating age have been experiencing abnormal periods. Today I am still in so much pain it?s debilitating however it is less sever than yesterday (Friday) and the fatigue also continues even after sleeping 10 hours last night.

Menstrual cycle started 8 days early and began a few hours after receiving my first dose of the vaccine.

Menstrual period with heavy bleeding and moderate to severe cramping began less than 24 hours after injection, despite Mirena IUD with active hormones that has stopped my regular monthly periods since 2016.

Five days after. My second Moderna vaccine, my period came weeks early and was heavier than usual. Then I had another period about one week later. Now I am having cramping and spotting/irregular bleeding.

I had my period two weeks ago and fell on it again. It?s really heavy and contains lots of clots. Menstrual cramps.

I have endometriosis and my periods are heavy with painful cramps first 2 days and my period is done by the 4th day. I take aleve a day before my period which helps with my cramps. My last period started April 9th and I am still on my period today April 15th. I had heavy bleeding and blood clots the size of quarters for the first 5 days. The aleve didn?t seem to help and my pain level was at a 10, I would pass out from the pain. My period usually last 4 days and I am on day 7 and still bleeding, but not experiencing any cramps. I?ve read that Covid effects the blood clotting process and also read other women are experiencing heavier menstrual cycles after their covid shot. I also read that moderna didn?t study any side effects related to the menstrual cycle. I have an appointment today (April 15th) to get my second shot. I am not sure if I should get the second shot, due to the amount of clots I had.

Never have had menstrual issue untill now after getting first period after trying shot last week. Heavy period. Multiple With large clotting. Some clots larger then half dollars. For over a 2 hours. Which have never experienced before. Also muscle aches that are abnormal and breast pain

Onset menstrual period outside of regular routine, and just 2 weeks after completing a regular cycle period. Patient regularly takes her birth control pill.

Period started a week earlier than normal four days after receiving the vaccine (always on time and track it), lower abdominal cramping, heavy bleeding/spotting very unlike normal light flow experienced.

Horrible stabbing cramps during my menstrual cycle. I never ever get cramps normally, so this was very unusual for me. It was so bad that I had to leave work and cried in pain on several occasions.

Irregular Menstrual cycle I have had a regular menstrual cycle since 11 years old. I received the second Moderna shot on March 27. I was on my period/cycle on my shot date- March 27, 2021.. I starts very light bleeding on Saturday April 17th- the bleeding has increased and is very heavy today (4/21).

Within 8 hours (evening same day), nausea/lightheaded and chills continued until late night Thurs. 04/22 (~30 hours after vaccine). My period started about a week (5-6 days) early (two days after I received the vaccine). Cramping has been worse than normal.

Menstrual cycle changes. Menstrual cycle started 7 days early and unusually heavy and longer. No treatment.

Extremely heavy menstrual cycles ever since, bleeding during luteal phase despite normal progesterone levels (had them checked). Basically I?ve been spotting or bleeding for half the month ever since my vaccine.

Hives and wheezing within 2 hours. Had itching redness also. Very heavy period started within 2 days with severe cramping and large blood clots. That lasted for several days then stopped then started again. Still experiencing side effects one week later. Also felt nauseous and tired.

My periods started on April 17 as it should but it never stopped. I am bleeding for 16 days now and usually, only 4 days. I?m not stressed or anything so it can seriously be related to the vaccine.

2nd Trimester Miscarriage of Healthy Baby 2nd pregnancy, no hx of miscarriage prior, full term pregnancy with first. All genetic testing on mom and additional health screens of baby were normal. On 4/25/21, lost mucus plug in the AM at 17 weeks pregnant with no other issues, concerns, abnormalities, etc. At 3:50AM on 4/27/21, ruptured membrane/water broke. Hospital testing confirmed 100% break of amniotic fluid with nothing left to sustain baby who had normal heartbeat and was still alive - measuring on target. Induced at 11:20pm on the 27th and delivered at 5:30am on 4/28/21 at 17 weeks and 3 days a baby boy measuring 8.25 inches and 5.6 ounces. No placental infection or abnormalities. Pathology noted an abruption hematoma that could have resulted from induced labor. No trauma, blood work, or other explanations for early rupture of what was a perfectly healthy and growing baby.

On 3/4/21, I was informed that I was pregnant with my 4th child. On 4/12/21, I was scheduled for my 1st dose of the Moderna as well as having a first trimester NCIT testing being done. At that exam, my provider was able to find a fetal heart rate (177), he was dated to be approximately 12 weeks and 6 days, and there were no concerns at that time regarding physical abnormalities or brain deformities. Additionally, I was sent out for bloodwork to rule out Trisomies and determined gender of the baby. The results of that lab work came back as negative and we were expecting our first son October 19, 2021. However, yesterday, 5/4/21, I attended my monthly prenatal appointment and the provider informed me that she could not find a heartbeat. She used a doppler scanner and then the in office ultrasound machine; neither of which detected a heartbeat. I was sent out to Radiology for a formal scan to refute or affirm the findings. Sadly, the results came back that I had lost my child. There was no heartbeat found and the results showed that my child stopped growing and remained 12 weeks in size. I am scheduled to have my pregnancy evacuated Friday, 5/7/21 at 1040a. While I am aware that miscarriage in 1 in 4 women, I cannot in good faith say that the vaccine may have contributed to my pregnancy loss. The only change in my routine was the addition of the vaccine. I am hopeful that this pain will not be felt by others and can be researched further to ensure fertility loss or future pregnancy loss isnt a norm following this vaccine. Additionally, I have had 3 full term, healthy pregnancies prior to this miscarriage. None of these pregnancies had complications and the children were birthed without issue.

Period is all out of whack, started early after first dose and now spotting after second two weeks early.

My period is a week late, yet two home pregnancy tests I took were negative. First dose did not affect my period at all. I have always been regular, give or take a few days. I am in the process of switching doctors, so I could not go to a doctor yet, and I did not have medical info to list.

With in seconds of receiving the vaccine I became really dizzy and light headed, my heart also began to race and my whole body felt really warm. The doctor was really nice and let me lay down and wait the suggested 30 minutes. I also felt like I was stoned for 3 weeks after receiving the first dose. The best way to describe it would be a sense of tiredness/ fog like feeling with on and off feeling of vertigo whenever I moved my head to the right. The vaccine also messed with my menstrual cycle. My period came 10 days early and I spotted 3 days prior to it actually starting with is abnormal for me. I also became very dehydrated, I drink more than 80 ounces of water day day so this was also a cause of concern. My lips became discolored, I had patched of red spots on my upper lips which I associated to the vaccine. I went to the doctor and they assured me that it wasn't due to the vaccine and brushed off the above mentioned. They said I may have an active case of COVID and they tested me. The results came back negative. Along with these symptoms I also experienced headaches and chills and a sore throat with in the first 3 days of receiving the vaccine, which was expected. The reason I'm filing this report is because I feel I have no support from my doctor and these are the typical symptoms after receiving the vaccine. Hopefully you will find this information useful in your research. And for the record I still don't feel normal.

Initial dose 1/4/2021 second 1/29/2021. I was a little over 8 weeks pregnant when I had a miscarriage on or around 2/09. I was not aware that the baby did not have a heart beat at that time but learned at an ultrasound on 3/9. I had an d and c. The baby was due on 9/23/2021.

First Shot on April 14 2021 Normal occurred on regular cycle on April 28 Secondary/unexpected period started May 11. Very heavy cycle.

Hormonal changes. Severe PMS, cystic acne, and menstruation began 2 weeks early in my cycle that is never off.

1 Week after my 2nd dose I developed a rash on my lower right leg. It became very itchy and red. I was prescribed a topical cream to use. Over the course of the next 4 weeks the rash got bigger and spread to the left lower leg. I was prescribed different topical creams, had a Kenalog injection but nothing was working. The itch was temporarily relived by the Kenalog injection. I ended up getting a punch biopsy and it was determined that I had eczema in parts of my leg. I was referred to a dermatologist and was also told I had hives as well and was put on a 2 week antihistamine regimen. Also, 1 week after my 2nd dose my mentral cycle lasted 36 days and my period was about 7 days long. This continued for 2 months. My cycles usually are 24-27 days and my period is only usually 4 days, maybe 5 max.

Fever, nausea, upset stomach, chills, sweats, prolonged menstral period, hot flashes, muscle aches, headache.

I had stomach cramps the first night which didn't seem irregular as I was on my period however by the second day they were severe and in my upper stomach bellow my ribs and my period had lightened so I was able to tell they were not related to my period. On the evening of the second day I began severe diahrea and still have it on the third day. I have been nauseous since the evening of the first day. Pain in the injection site was minimal and nearly gone on the third day. I did experience some numbness in my arm immediately after the injection.

Sore arm for 3-4 days flu like symptoms for 2 weeks period came 4 days early (never happens) within 2 weeks brain fog continuous extreme fatigue continued depression increase continued acne began 1 week after and continues

Headache, nausea, fever, chills, body aches, fatigue, mild pelvic ache starting around ovulation and lasting till period begins. This started the month after 2nd dose.

Incredibly bad period cramps and lower back pain, starting 1 day before start of menstrual cycle and lasting until day 2 of the cycle. I normally experience very mild cramping fon Day 1 and nothing else. Treatment consisted of Ibuprofen every 4 hours and application of heat. Symptoms were debilitating even with treatment for 2 of the 3 days they persisted.

Second shot was received on 4/30/2021. My very regular and predictable period was due on 5/7/2021. The shot delayed my period by 1 week and it started on 5/14/2021. 5 pregnancy tests were taken in that week and all were negative. I track and chart my cycle closely because of my endometriosis so I'm able to plan my life around my debilitating symptoms. I did have the typical feeling really bad and stuck in bed the day after the vaccine. However, the day after that, 2 days after the shot, my typically debilitating premenstrual symptoms were stopped and I felt great, better than I have in a long time. Until the day before my period started on 5/13/2021 when I got a migraine (not typical for me) The migraine continued for 2 days. I was bed bound for those 2 days between the period pain and the migraine. The 3rd day and the last day of the period I felt much better and was able to resume regular activities. My period typically last for 5 days and is usually very heavy in the first 2-3 days. This period only lasted 3 days and was much lighter flow than is normal for me.

For both vaccine doses, does one given 4/12/2021 and does 2 given 5/10/2021 I had a change to my menstrual cycle. Does one on 4/12/2021 caused a period 10 days after administration when the normal cycle should if I stayed on track should have been 20 days later instead. Dose 2 also caused an abnormal/early period 10 days after administration when the normal cycle track should have been 26 days after administration. I do not typically have issues with my menstrual cycle, in fact, they are usually on time within 1 day and have been my entire life. I do not take birth control or have any other issue that I am aware of that would cause this.

Menstrual bleeding for 3 weeks (so far) despite being on continual birth control and not having any Menstrual bleeding for 3 months prior

I was 7 weeks pregnant at the time of receiving Dose 1 of the Moderna Covid vaccine. I began experiencing vaginal bleeding on Wednesday April 28. The bleeding continued and began heavier so I went to Urgent Care on Friday April 30. May 1 I experienced a miscarriage and lost the pregnancy.

Fever. Muscular discomfort and dizziness 26 hours after vaccine and then urticaria all over body that has been going on even up to today that's 30 days going down every day. I am presenting with amenorrhea x5 days late, what we don't know is if it is due to the vaccine but it coincides. Inflammation and fluid retention some days worse than others.

1.) Mild headache and moderate body aches with low grade fever beginning day of vaccination, dissipating on day 2. 2.) Arm soreness and minor rash at injection site appeared 8 days after vaccine administration, lasted approximately 2 days. 3.) First post-vaccine menstruation was 12 days early and noticably heavier than usual with increased cramping and body aches.

My period got messed up. I got less bleeding for 1 day. Period stopped then bleeded heavily. It lasted for 2 periods after vaccine. I am better now Also first months after vaccine.. I was out of energy and so sleepy all the time

Following the first, I got a respiratory illness for over a week. Following the second, I could barely walk and have not had a menstrual cycle since. I have missed my last 3 cycles. I have NEVER had an issue or missed before. I received 2 blood tests and was not pregnant, and neither show any reason to have missed it. I have no health issues, I am healthy, I just turned 36, have 2 healthy kids, exercise daily and eat properly. The only explanation for missed cycles would be the moderna shots I received.

03/04/2021 I had my last period. Then I had the second dose and a month later I knew I was pregnant and then I had a missed miscarriage. They gave me misoprostol and misoprostol. After the missed miscarriage I was dizzy because I lost blood.

I was violently throwing up for about six hours, sweating, chills, and I couldn't eat for about two days. I was extremely weak. after I recovered from the two days of being miserable, my neck got really swollen and sore. I had mild soreness in my right arm at the injection site as well, but it wasn't as sore as the first shot. I drank a ton of water and took the tylenol muscle soreness medicine. In addition to soreness on my left arm (injection site) from the first shot, my period also got heavier and I have spotting in between.

Patient called the pharmacy a few days after her 2nd Moderna vaccination and stated about a day after her shot she started experiencing abdominal cramps. Patient was pregnant so was very concerned and went to the hospital. Unsure how far along she was but she wanted us to know she had a miscarriage. We are unaware if this is linked to the vaccination but patient is stating that's the only thing that has changed since her three previous pregnancies that had no issues whatsoever. Reporting this since she called the pharmacy so we were aware and since we are not aware if the hospital filed this report.

Chemical pregnancy experienced 3 weeks after 2nd shot in Moderna vaccination cycle. No reason to believe it was a related event, but reporting it nonetheless in case a trend emerges. Some flu-like symptoms (body aches, headache, fatigue) were experienced 24-48 hours after the shot but no fever.

Not sexually active No period in Feburary or March 2 months missed period 1 normal period in April no period in May Currently no period as of June 16th OTHER: Chest pains Sharp

COVID arm, redness, itching swelling and pain. Started menstrual cycle June 14 and it was severely heavy and painful which is not a normal cycle for me. I don?t have heavy cycles. Treatment for covid arm was benedryl for 3 days until the rash disappeared.

I received the Moderna COVID19 vaccines on 1/22/21 and 2/24/21. I became pregnant shortly after my 2nd COVID19 vaccine. At 12 weeks pregnant, I found out that I had a Missed Miscarriage, and had to undergo a Dilatation and Curettage procedure.

I am still dealing with severely debilitating back pain, that is made 100x worse when I have my period. This started after my boyfriend and I had intercourse for the first time after he received the Moderna vaccine for fear of losing his job and his employer was pressuring every one to get the experimental vaccine. I did not receive the vaccine however my report is based on the following reasoning: on april 27th 2021 he received the vaccine on may 4th we had intercourse for the first time since he has the vaccine. immediately after intercourse I could feel a burning stinging pain in my uterus/vaginal area that slowly started to radiate from the base of my tail bone to the base of my neck it feels like a burning sensation. it is made 100 x worse when i have my period. my doctor has prescribed me physical therapy exercises which do some what dull the pain, but it back to the same level the next day. sitting hurts i can feel it all the time it hurts to hold objects such as my cell phone when walking from the weight prior to this i was 100% healthy. I am reporting this based on the following information: 1.Ex Pfizer lead scientist said that: " The vaccinations are expected to produce antibodies against spike proteins of SARS-CoV-2. However, spike proteins also contain syncytin-homologous proteins, which are essential for the formation of the placenta in mammals such as humans. It must be absolutely ruled out that a vaccine against SARS-CoV-2 could trigger an immune reaction against syncytin-1, as otherwise infertility of indefinite duration could result in vaccinated women." In addition, another mRNA vaccine technology founder, has also stated that the spike proteins can be shed via bodily fluids: "The vaccinated "shed" tiny amounts of spike protein (in urine, etc.)" As well as this article that says that MRNA is transmissable via semen: "The existence of a complex population of mRNA in human sperm is well documented but their role is not yet elucidated." In addition, there have been several females who have come forward from the vaccine trials who have had severe neurological issues from receiving the vaccine.

I received the COVID-19 Moderna second dose vaccine on May 5, 2021, at around 1 pm. The night after the vaccine, I had the typical side effects from the vaccine, which are chills, arm pain, severe fatigue, headache, slight fever. By the second day, chills were subsiding but I still feel very fatigued until the afternoon. Then by the third day, which was May 7, 2021, at around 2 am, I started feeling some chest tightness, which at first I associated with back pain. However, as the day progresses, I started feeling short of breath, on and off chest pain, and palpitations. I decided to go to the ED around 10:15 pm, due to shortness of breath, and chest pain was more pronounced. Upon my arrival in the ED, I was tachycardic at 110. I was triaged and the ED physician ordered did blood work including D-Dimer, EKG. EKG reveals sinus tachycardia. The blood work reveals an elevated D-Dimer which was 1.06. And due to elevated dimer, the physician ordered a CT scan chest which was negative for PE. Since I was still having some shortness of breath and chest pain, I was admitted as observation, for telemetry monitoring and repeat EKG. The following day, I was discharged since the chest pain was resolving. However, I continued to have palpitations for at least a week after the vaccination. At that time, the ED physicians were not sure if my symptoms and elevated dimer were related to the vaccination. I followed up with a cardiologist and my PCP a few days after the hospitalization. I followed up with the cardiologists because of my history of pulmonary hypertension 5 years ago which I believe was resolved, however, it was a concern for the ED physician, because at the time they were not sure of what is the cause of my symptoms. During my visit with the cardiologists, he believed that my elevated dimer was due to the vaccination (possibly due to the inflammatory response), as well as the symptoms I have which was pericardial pain. I did my echo last week, and I will need to do another blood test this week, to check my dimer, and cardiac enzymes. And now, since I had the vaccination, I have not had my period for 18 days, which is very uncommon to me. I had my period a few days after the vaccine. All my pregnancy tests are negative. So I am scheduled to follow up with my OB-GYN. I believe that my delayed period is also related to the vaccine, but of course, I cannot conclude that until I see my physician and conduct all the tests needed.

Irregular menstrual bleeding (bleeding started again, last day of last period was 1.5 weeks ago). Extreme fatigue. Severe pain (6 out 10 pain scale) in right arm. Headache/migraine that has lasted 2 days. Body aches. Chills. Thirst.

Skipped a period. My last period was April 16-20. I had a 2nd Covid Vaccine April 23--didn't have another period until June 9th. Skipped my expected May period altogether. Definitely a result of the vaccine--I've never fully skipped a period before outside of pregnancy (at most up to 2 weeks late). Just wanted to report it as FYI, since it doesn't seem to be being widely reported as something women can be prepared to expect. No need to follow up with me regarding results of any investigation, just adding my data point to the body of evidence.

On May 21, 2021 I had a positive pregnancy test. We were preventing conception and were very surprised. On 5/27/21 at 12:30 pm I started having vaginal bleeding and went to Hospital ER where I was told I was having a miscarriage. I have had two pregnancies and 2 lives births, no previous miscarriage

About 45 moments later, I had a Fibromyalgia flare up. I was so achy I had to take ibuprofen and lay down. A couple weeks later, I had a flare up with my endometriosis as well. I started getting bad pain in my pelvis area. I went to the gynecologists' because the pain was so bad. The pain was off and on for several weeks. The doctor gave me pain meds and performed an ultrasound. They found a cyst. These symptoms continued on, during, and after my second dose. I received surgery to remove the cyst and some scar tissue.

Period bleeding for 2 weeks at a time, every 2 weeks. Bleed 2 weeks, stop for 2 weeks, then bleed again for 2 weeks

Received vaccine on 1/4. Started menstrual cycle on 1/16 which was 1 week early. 3 days into the cycle, heavy vaginal bleeding with large blot clots (golf ball size) starting on 1/20/201 and continuing until now 1/31, bleeding still going on.

I received the vaccine in my right arm and within 3 days I noticed some painless swelling around my right areola scar line where I had a breast lift and implants 11 months prior. This progressed to two open wounds where sutures began to surface and had to be removed. After my second dose of the Moderna vaccine I developed another area on my right areola scar line that opened up to reveal another suture that required removal.

Had a slight rash on the front of my chest and one big round rash on my back. I also started to have vaginal bleeding when I wasn?t due to have a period. The rash got progressively worse, to spread all over torso back and front. Vaginal bleeding also continued to worsen. Went to ER to have labs checked, was told it looked like Pityriasis rosea- and that all lab values and clotting factors were normal. Sent home with prescription for Atarax if needed. Was told it would be self limiting but if worsened to come back.

Wife did not know she was pregnant at the time, had the vaccine and miscarried the child at 12 weeks. OBGYN stated baby had miscarried 2-3 weeks earlier. D&C procedure performed 2/23 to remove remains of fetus.

Large red rash appearance around injection site. Began to get bigger. Then part of it disappeared and reappeared further down my arm with pain upon touch or movement. Woke in the morning with a bad nose bleed (took about 20 minutes to control it) On birth control, yet I have been having ?spotting? for the past few days and period is not due for another 2 weeks.

On the following day after receiving my first dose of the vaccination, my arm was throbbing, completely swollen, decreased ROM and skin was RED and severely tender to the touch. Took OTC Tylenol (2) po and had no signs of relief. Pain , swelling, and skin redness lasted for 3 days. On February 10th, 2021 I had a positive pregnancy test (confirmed by bloodwork and urine) which indicated I was 6-7 weeks pregnant and had a miscarriage on March 2021, after giving live births 3 prior times. The cause of the miscarriage is unknown. I also developed a blood clot on the arm that was inserted for an IV. I have no family history or personal history of needing blood thinners.

--fever begin approximately 24 hours after vaccination and continued intermittently for five days, controlled by Tylenol, just longer than expected 24-48 hours; accompanied by standard symptoms of body aches, etc. for only 24-48 hours --period started three days early, which is practically unheard of for me; I should have started on Wednesday 2/10, but started on Sunday 2/7; this is similar to my first dose (given on 1/6) after which I started my period two days early on Monday 1/11 instead of the expected Wednesday 1/13; since I'm reporting this so late, I'll also share that my most recent period would have been expected on Wednesday 3/10, but started on Monday 3/8

Pain at injection site starting one day after 2nd pregnancy (first was miscarriage), due date November 12

Severe headache and abdominal cramping the day after on 3/19. Followed by worsening cramps and vaginal spotting from Saturday 3/20, Sunday 3/21, Monday 3/22 and Tuesday 3/23. Ultrasound was done on 3/23/21 at 14 weeks 1 day pregnant and no fetal heartbeat was found. EDD was 9/20/21
