I ended up starting my period April 20, 2020 (same day I got the vaccine) and it was the heaviest cycle I've had in years. I went through several tampons in a day for about a week til my period abruptly stopped on April 26, 2020. It started about 2 hours after the vaccination. I usually don't cramp but I was having problems sleeping because of how bad it got. I was also more bloated than my usual cycles. I dealt with extreme fatigue, I slept a lot that week and I did the bare minimum that week at work (which is unusual for me). I also don't usually have mood swings but I felt like my hormones were a bit intense to the point I kept snapping at people even though I like to think of myself as level-headed.

It?s been a week after my second dose. I?m having an extended menstrual cycle since the 12th of April. After the second dose it?s extended my period and made it extremely heavy, having lots of clots in my cycle, still having tingling and numbness in my right forearm, tingling/ itching in my ears, very tired all day. The main concern is that with the vaccine I?m of day 17 of my period and it doesn?t seem to be slowing down just getting heavier.

During my next menstrual cycle following the first shot, I had heavy bleeding and cramping which had still not stopped after starting my new pack of oral contraceptives. I usually do not bleed at all on my birth control.

My period/menstrual cycle is highly irregular following receiving my second dose of the vaccine. I was on my period while receiving the second dose, and this period lasted around 2.5 weeks, with spotting on and off afterwards. After only a week or two off of my period, I am now spotting again as of the time of this report.

Symptoms: Very sore arm that went away in a day. Light period that has continued over a week after the shot was given. Period is still present but getting lighter and lighter.

The day after receiving the first dose of the Pfizer COVID-19 vaccine, the patient began to experience heavier than normal menstrual blood loss and blood clots.

Discharge and uterus bleeding, sharp lower belly cramps, fever and fatigue, irregular menstruation, nausea and vomiting

Since two days before the second vaccine, I have had my period, which has now been for more than a month. I have a LARC, which has caused me to not have a period prior to this for probably about the last 6 months.

1st shot - Mild reaction to first shot, itchy everywhere. 7mins after injection. Taken to ER (shot was down at local hospital) and given some antihistamines and felt fine afterwards. 2nd shot - No reaction right away like the first one, migraine for 2 days, went away. Main concern though is that my period is currently 2 weeks late after I received my second shot. I have taken multiple pregnancy tests and they all came back negative. Apparently a bunch of my friends have had the same side effect but they told me it comes back after a month. I?m surprise that this isn?t listed as one of the side effects of the vaccine. I was ready for the side effects listed but when I haven?t had my period I was worried and didn?t realize other women were having this side effect also. I feel this should be told to women in order for them to prepare that this could be a side effect. Also it?s not just me, apparently there?s been a ton of woman about it on the internet talking about it and many of my personal friends have the same experience. Please be more open about side effects with women?s bodies.

The patient was not received any other vaccines within 4 weeks prior to the COVID vaccine. Prior to vaccination, the patient was diagnosed with COVID-19. Since the vaccination, the patient hadn't been tested for COVID-19. Not known allergies to medications, food, or other products.

My last period started Tuesday Feb 2nd and did not stop until 14 days later, more than double my usual menstrual cycle. It seemed pretty normal and painless, but then on 8th day I was surprised to find myself still bleeding . It was a darker color around then, but then became brighter and I noticed myself passing clots when I went to the restroom that were loose, but about the size of a quarter or half dollar. I did not bleed through any menstrual pads, but the return of bright red after it being a darker red that im used to at the end of a period had me concerned. I was in slight discomfort around my uterus/bowels and I couldn't tell if it's my body recovering from the vaccine, or something else. I received my second dose of the COVID-19 vaccine 2/11/21 (Pfizer) and stayed home from work as I had a fever/headache/chills (this was not unexpected to me, my coworkers had the same symptoms). Family medical history: grandmother (dad's mom) in remission from stage 4 uterine cancer about 5 years ago. Mom had endometriosis at 45 and had a hysterectomy.

I was 6 weeks pregnant at the vaccine, two weeks later I started bleeding and had a miscarriage. Exactly 2 weeks after the vaccine. I left work that day to see the OB , had ultra sound, labs and a follow up a week later.

The patient began having vaginal bleeding and contractions on 3/11/21 at 24 weeks 6 days and presented to labor and delivery in preterm labor. We were able to delay delivery for about 24 hours but she did deliver at 25 weeks 0 days. Earlier in her pregnancy she had some vaginal spotting (last time was on 1/15/21 and her cervix was closed on sonogram). In her first trimester she had significant hyperemesis treated with medication and IV fluids but this resolved after the first trimester.

At time of vaccine (04/07 11:45 AM) was light-headed and had shoulder pain at injection site but no other adverse effects during observation period. While driving home, had some tingling/numbness in left arm and knees with persistent pain in shoulder. Felt fine other than shoulder pain and slight headache until that night. I went running after finishing work (around 7 pm) and started experiencing intense tingling/numbness all down left arm to hand as well as intense knee pain not typical during running, at which point I stopped running and went home. When I got home I noticed my left index finger had lost circulation (was white). That night I experienced moderate but increasing fatigue as well as chest pain and tightness. My hands both felt numb like they fell asleep/lost circulation, as well as my left arm and feet. The next morning I felt better but the fatigue and numbness in my hands and feet started up again around 10 am and lasted for several hours. I had some chest pain that night (around 11 pm) and a headache on and off throughout the day. Today (04/09) I felt completely fine. I did start my period the day before my vaccine (04/06) and was having heavy bleeding/cramps that day and a bit throughout the time described above.

After receiving the second dose of the Pfizer COVID vaccine, I had severe flu symptoms (chills, nausea, body aches, cold sweats, migraine, fatigue) starting about 7 hours after the injection and lasting for approximately 20 hours. The evet that I was primarily concerned about was that, about a week after the vaccine, I started my menstrual cycle and got a period. My IUD has prevented me from having a period for 2.5 years, and so it was alarming to get one suddenly out of nowhere. While this was obviously not a life threatening event by any means, I wanted to report because of how unusual it was so that if other women are having this experience (or any changes in their menstrual cycle) there will be appropriate documentation to list it as a side effect, and help alleviate anxiety by informing women this is a possibility following being vaccinated.

One day after receiving my first dose, I began to experience heavier than normal menstrual bleeding for a little over a week. I have been on birth control for the past year and my periods are normally shorter and lighter.

Once my period started, (somewhat on schedule) I had terrible period cramps. Worse than I've ever had before. I very rarely get cramps at all, and these were certainly the worse I've ever had. Pain was bad enough to prevent my ability to work and to some extent move at times. This is not something I have ever experienced before. Reporting because I have heard anecdotally from close friends about changes in their periods after the vaccine as well. I had not heard of this until after I was already done with my period, so it wasn't something I was expecting or in my opinion not placebo related since I did not hear about possible period-related side effects until afterwards.

Got heavy period 6 days later while in middle of birth control pack. Also had the common fever for about 36 hours afterwards.

I received my second dose of the Pfizer vaccine on February 23rd 2021. That same day I discovered I was pregnant. On March 26th 2021 at my 9 week appointment ultrasound I discovered that my baby had no heartbeat.

Menstrual cycle started 14 days early, and lasted 15 days. Mostly a light period but completely abnormal.

Very tired on the day of the vaccine, then starting to have period cramp, then 4 days later started my period after not having a period for 2 years due to IUD.

I'm not sure if this is related to the vaccine, but it's really strange timing. I received my 2nd COVID vaccine last week and now my period is 5 days late. I'm not pregnant. My period hasn't been this late in the last 15 years. It seems likely that this is a vaccine side effect? I decided to report it just in case!

Menorrhagia (heavy period/ menstruation) My period usually lasts for 3-4 days and is fairly light after the first day. However, my period after the COVID 19 vaccine lasted 5-6 days and was very heavy for the first 4 days. This was accompanied by worse than normal menstrual cramps as well.

I received my second Pfizer shot on 4/6/2021. My period began on 4/13/2021 and it was my first cycle since getting either vaccine dose. I typically do not have mensural cramps during my cycle but I had cramping that was so painful on the night of April 13th I could not sleep. It was excruciating pain. I had to medicate with motrin in order to get a few hours of sleep that night.

I bled in the middle of my cycle, which I have never done before. I then seemed to start ovulating very late in my cycle, which also has never happened before. I am currently nearly one week late for starting my period, and I have always been extremely regular- every 28 days.

Missed Miscarriage discovered at routine pregnancy ultrasound on 4/6/2021 (12 weeks 5 days pregnant) Deceased fetus measured at 9 weeks 5 days D&C performed as a result on 4/7/2021 Estimated due date was 10/14/2021

I did not get my period after second dose. I got my first dose on 3/11/2021 and got my period after, like normal. However after my second dose on 4/03/2021, I did not get my period on 4/19 as usual. I am on birth control (kelnor) and am therefore extremely regular. I took a pregnancy test and it was negative. This is not at all life threatening, but I hope it is researched further.

Extreme mood swings, depression, back pain, fatigue, extreme cramping, heavy spotting between periods with clots, brain fog . Spotting stopped yesterday on its own 4/30/21

pt says she took a pregnancy test before taking the covid vax that read positive. she had a sore left arm for about 2 days. On 4/5/2021 she had some vaginal spotting but pregnancy test was still showing positive. On 4/7/2021 she went to her PCP. They gave her a pregnancy test that was positive. They expect she was about 4 weeks along. She was referred to her OB/GYN. On 4/10/2021 she had vaginal bleeding. She contacted her PCP and was instructed to go to the ER. She went to Medical ER. they did a vaginal US, US on her stomach along w/ urine test. She was told that all results were negative and there was no longer a fetus. She was about 5 weeks along at this point. She has never been pregnant before but hormone levels are great before this incident.

My first menstrual cycle following the vaccine was extremely heavy, with a lot of fatigue. I have never lost that much blood menstruating in the past, and at one point I briefly passed out due to the combination of fatigue and weakness from the blood loss. While it could be coincidence, I've never had a cycle like that before and figured it might be something that needed to be brought up.

2nd day started a fever, cold sweats, hot flashes, body aches 3rd day to 1 week later: loss of taste and smell, runny nose, foggy brain, 1 to 2 weeks later: nausea and diarrhea during ovulation cycle, spotting between cycles

Since the vaccine I have had irregular periods 45-60 days apart and they are very irregular. I have bleeding in between for days at a time and cramping. Before the vaccine I had a period 28-30 days apart that were regular and predictable. Before the vaccine I never had spotting or cramping between periods.

spontaneous abortion; This is spontaneous report from a contactable nurse.

R56.9 - Unspecified convulsions N93.9 - Abnormal uterine and vaginal bleeding, unspecified VAGINAL BLEEDING HEADACHE

I went home and took a nap, when I woke from my nap my right side (injection side) was numb. My face around my nose was numb down to my waist line. It was like half of my body was asleep, like when your arm or foot goes to sleep, that was the feeling on my right side. Everything was normal on the left side. Woke up the next morning and my migraine started, I kept a migraine for the next 4 days. 3 Days later I started getting feeling back everywhere except my shoulder blade and arm. Once I regained most the feeling I had cramps where I would normally have menstral cramps. Thursday 5/13 I started spotting. It was more of a flow and stopped by Sunday afternoon. as of Tuesday 5/18 my right arm has a little feeling but it comes and goes mainly my upper arm and shoulder are numb still.

The night following my first dose, I experienced the worst mentrual cramping I have ever had in my life, so much so that it felt like I was having contractions. As I have an IUD, I have not had a period for over two years now, though I do experience cramps during the time in my cycle where I should bleed. The cramps experienced were nothing like my normal menstrual cramps, I was doubled over in pain. And on the third day after the shot, I bled for the first time in 2 years (since getting an IUD). My breasts also doubled in size and extremely painful.

In the middle of the night I had chills, a headache, and body aches as is to be expected. The fatigue and headache lasted two days, but all of those side effects were minor and manageable and are well worth it to avoid covid-19. A couple days after I got the shot, I got my period and it was nine days early. That never happens to me. My cycle is pretty regular and is never early. I additionally experienced much heavier bleeding than usual as well as worse cramps.

First dose as well as second dose of the vaccine was followed by immediate vaginal bleeding which lasted for a week. Bleeding is still ongoing after the second vaccine shot. A red spot in the eye has appeared without any known reason.

I was 10 days late on starting my period. I have not been even a day late for over 8 years. Typically, my cycle even runs a couple days early.

Systemic: Abdominal Pain-Medium, Systemic: Miscarriage-Severe, Additional Details: Pt had miscarriage after first dose of Pfizer vaccination. Bleeding started hours after shot.

I have an extremely heavy period now, I woke up and there was a huge blood clot in my underwear and I literally gushed blood I?ve never seen that in all my 27 years of living and I?m afraid of what the next few days of my period will be like.

I have had period spotting since the day after receiving the first vaccination despite being on my regularly dosed birth control.

Vaginal bleeding began 4 days after my covid shot on May 11th and is still continuing to this day, June 11th. I passed 4 blood clots between the days May 28 and June 5th. On May 28 and May 29, I was bleeding uncontrollably from my vagina and having to changing pads and pants every two hours. THIS DOES NOT REFLECT MY NORMAL CYCLE OR PERIOD Next, perfectly healthy before May 11th and this covid shot i had to undergo appendix surgery and had to get my appendix removed, and during surgery it ruptured in my doctors hands. Before this shot, I was a completely healthy and active 27 year old female.

A few weeks after my second injection, I had a very heavy period. I?ve had a period every 2 weeks since the first incident and I?ve never had that problem in my life. In fact, I have the opposite problem where I very rarely get periods, so having them every 2 weeks is completely out of the ordinary for me.

During my first period after receiving the vaccine, I experienced markedly worse menstrual cramps than usual throughout the day. I took Midol extra strength to combat the pain. I couldn't sleep until approximately 2:30 am, and I woke up at 4:00am due to the pain. I noticed that my vagina itself was swollen on the inside and essentially numb - even as my abdomen was cramping painfully. After sitting in the bathroom for a while, I tried to stand. At that point, I briefly passed out and collapsed into the bathtub. This has never happened before in my life.

I am on oral contraceptives and my period started in the middle of a pack two weeks after the end of my last period. I have been on the same birth control for 11 years and this has never happened. I did not miss a pill or take one late. I had extreme cramping within 24 hours of the first vaccine. The day after the cramping started, I had the heaviest period I've had since I began birth control 11 years ago.

The week after vaccination I was admitted into the hospital for severe menstrual bleeding. My CBC result shows a platelet count of 17 10*3/uL, accompanied by low white blood cell and red blood cells count. I received multiple transfusions (2 units of whole blood and one unit of platelets), and was diagnosed with ITP. I then received steroid treatment (Dexamethasone, 40mg/day, 4days), after which my blood counts are restored.

Started on the morning of 6/25/2021. I received my second dose of Pfizer COVID vaccination after my menstrual period ended and this morning when I woke up, I noticed that there was blood on the toilet paper. There was no blood in the urine and throughout the day, there continues to be an increase in the amount of blood left on my pad and tissue paper. Haven't had issues with spotting in the past and this is a new occurrence. Also feel that my left posterior auricular lymph node is harder and more swollen and left sinus is more congested.

First menstrual cycle after vaccination resulted in spotting for several days after typical menstruation end date. Spotting varied from minor to medium somewhat randomly for several days past the typical cycle end of ~7 days. Patient has never experienced this type of spotting before. Second menstrual cycle during the following month was both heavier and more painful (cramp inducing) than normal, though this time it did not result in spotting after the normal cycle number of days.

Fever, migraine, anxiety, light headedness, anxiety attack led to fast heart rate, shaking legs, feeling faint, menstrual cycle either missed or late by 3-4 weeks (not pregnant)

I have had my period twice in the last four weeks since my vaccine and three times in the last six weeks.

abnormal vaginal bleeding. I completed my period on 6/24/21 and less than 2 weeks later I was bleeding heavily again. I have very regular periods. This is not normal for me.

Reported as Started menstrual bleeding about 24 hrs after infection. I didn't think anything was abnormal at first, but I am still having bleeding 2 months later. I have never experienced prolonged menstrual bleeding before. My periods have always been no longer than 4 days in length, with some missed periods here and there. I have been to see my GP and no direct cause could be determined at this time. I looked back on the date I received my first dose of Pfizer vaccine and the saw a possible correlation between that date and the onset of my symptoms. After doing some research I ran across this article and I believe there may be a connection to what I'm experiencing. As of this time I was still bleeding. No treatment received for the adverse events. The outcome of the events was not resolved. No follow-up attempts are needed; information about lot/batch number cannot be obtained.

To, The Centers for Disease Control and Prevention The patients. I am a 27-year-old female residing since August 2019. I am a Resident and an immigrant. On the 20th of April, 2021 I took my first shot of the Pfizer-BioNTech COVID-19 vaccine in where I reside. After 48 hours of taking the vaccine, I started experiencing extreme fatigue, dehydration, and chills. I also registered a fever of close to 101 on a few nights in the week after. I thought this was a temporary side-effect of the vaccine, but the side-effects persisted and was not dying down. Over the next 2-3 weeks my health condition waxed and waned. I was facing extreme fatigue to the extent it had disrupted my normal life, heavy dehydration, loss of appetite, feeling cold easily, especially in the evenings. I called up the center and asked if I could delay my 2nd COVID-19 Pfizer shot, but because it is generally advised to take the second shot within a 28-day period in the United States, I decided to go ahead and take my second shot on May 14th. I took a couple of Acetaminophen tablets this time to help reduce a possible fever. Over the next weeks, my condition did not seem to change, even though I was done with both my shots. I continued to face fatigue and weakness, I had lost 10-11 pounds, a huge loss in appetite, I started noticing heavy hairfall daily. My period had not come since taking the vaccine. In the early month of June, I noticed dark red blotchy marks that had appeared on both my arms. My health started deteriorating heavily in June, there were days when I could sleep all day. I started noticing a fever which climbed to 101-102 daily, especially in the evenings and continuous shivering. Seeing the signs of a serious medical condition, I filed for emergency leave from my workplace and decided to fly back to India where my family resides. I landed in the 30th of June, 2021. I was admitted to a hospital in the Emergency Unit on the very same day and where I continued to remain hospitalized until the 9th of July. I was hospitalized for a period of 10 days, during which multiple blood tests, scans and procedures were run on me, at the end of which I was diagnosed with now having a chronic illness, an Autoimmune disorder called Systemic Lupus Erythematosus. I am currently, recouping from my illness and undergoing treatment for SLE. I do not know if there was a correlation between my taking this vaccine and the triggering of my illness, but if there is a possibility of the vaccine triggering an Autoimmune disorder in healthy individuals, I would like the concerned authorities to make a note of it. Symptoms: Extreme Fatigue, Continuous High Fever, Heavy Hairfall, Loss of Appetite, Feelings of Nausea, Red marks on arms, Weight Loss, No menstruation

day after vaccine, expereinced severe cramping and menstrual bleeding very heavily. I was two weeks before my period which is VERY abnormal. lasted for five days

Heavy vaginal bleeding noticed a few hours after injection. I have been spotting (1 pad daily) because of my birth control, but now I?m using 6-7 pads a day and soaking through them. I?m not sure if it?s related but I?m also extremely fatigued and having chills. Should I ask for a blood test for my platelet count? I?ve read it is a very rare reaction for some to have lower counts.

I track my menstrual cycle using and typically experience a 32-day cycle; in the past year, the longest cycle I have experienced was 35 days. Received the 2nd shot of COVID19 (Pfizer-BioNTech) the day after estimated ovulation (estimated ovulation 2/3/2021; 2nd shot 2/4/2021). Experienced expected menstruation starting on 2/15/2021.

Injection site pain, left arm from shoulder to elbow, severe enough to make moving the arm difficult; started post-injection and escalated, peaking about a day post-injection and resolving after three days post-injection Mild fatigue, began about four hours post-injection and resolved about a day and a half post-injection Vaginal discharge, noticed the day after injection; may still have been ongoing two days after injection but difficult to say due to menstrual period starting two days post-injection Tylenol was taken in accordance with package labelling two days post-injection to mitigate menstrual cramps, which also helped the injection site pain

Missed miscarriage. Details about the pregnancy - EDD Nov02, 2021. First pregnancy. Tracking ovulation and dates. Mar19 - first dose of Pfizer. Mar22 - first ultrasound, detected sac/fetal pole, heart rate detected by slow at 100bpm. Measuring 1 week behind, pushing EDD to Nov12 Mar29 - second ultrasound, no heartbeat detected, no growth from previous week. Still had pregnancy symptoms, did not have symptoms after vaccine dose 1.

One month after having my second covid vaccine, I had the worse menstrual cycle of my life. I had heavy bleeding for 4 days and horrible menstrual cramps. So bad that motrin/tylenol did not take away the pain. Also passed a lot of clots. Also after my period, I've had continual bleeding/spotting. I've even gone to the OBGYN to get checked. I'm still bleeding...

Two days after getting vaccine, I spotted/possibly started period 2 weeks into cycle (which has never happened) and I feel terrible/bloated/anxious typical PMS symptoms. I also had soreness at the point of injection for one day after about 24 hours, but hardly a big deal.

Headache, fatigue, nausea, pain at injection site, muscle/joint pain, fever and sweats experienced Thursday/Friday after vaccination on Wednesday. Heavy menstrual period triggered on Saturday after very light spotting on Thursday/Friday (which stopped on Friday for a time). Period should not have occurred and was about 10-12 days early. Heavy bleeding with little tissue. Still on-going as of Sunday after vaccination on Wednesday. Also experiencing twitching/pain in calf muscles as of Sunday after Wednesday vaccination.

I was about 4 weeks and 3 days pregnant when I received my second dose of the vaccine. Everything seemed fine. The next day I woke up and I no longer "felt pregnant", but it was my first pregnancy so I did not think too much of it. Thursday I started having spotting and asked my doctor to do another BETA to see if my HCG levels were ok. That night I got the call that my levels had dropped and that I was losing the baby. I started heavily bleeding the next day. I have also had extreme back and muscle pain after each dose.

The evening after the first COVID vaccine dose, my sister noticed dark stained vaginal discharge, resembling beginning or late stages of the menstrual cycle. This continued for 2-3 days; with dark clots, with every wiping, and on underwear. Her menstrual cycle had finished for 8-9 days.

Irregular period. Spotting and then full blown cycle. This is irregular due to before receiving the vaccine I did not have a menstrual cycle.

Immediately after second dose: injection site pain, body aches, extreme fatigue, nausea, trouble breathing One month after second dose: early onset menstrual cycle, heavy bleeding, intense flow/clotting, hemorrhage-like event, prolonged period (over 7 days)

The day after I got my first dose of the Covid 19 vaccine, I started an extremely heavy period during a time when I shouldn't have had a period. The bleeding did not stop but was slowing down when I got my second dose. After the second dose, the bleeding started getting heavy again and has not stopped. I have a doctor's appointment next week. I'm reporting this because I saw some news articles where other women are having unusual bleeding from the Covid vaccines.

I was 4 weeks pregnant at the time of my second dose. I miscarried at around 7weeks 6 days. It was suggested due to potential Triploidy but I thought it would be informative that you know.

I was exactly 4 weeks pregnant at the time of my second vaccination. On March 23 I started to develop cramping in uterus. On March 25 or March 26 (I cannot remember exactly which day here) I started spotting, and then by the next day I was bleeding. On March 29 I saw my OBGYN who diagnosed me with a miscarriage. I continued to bleed for approximately 10 days, as well as dizziness, and feeling very faint. I have had 2 very healthy pregnancies in the past and no health issues. This could be absolutely unrelated, as early miscarriages are almost impossible to pinpoint, but I did feel this should be reported for researching purposes.

The next day after receiving my vaccination, I started having vaginal bleeding. However 2 weeks prior to my vaccination I already had my menstrual cycle. I typically either spot or have a small period that lasts 3-4 days due to my birth control (implant). Today 4/26/21, I am still currently experiencing heavy vaginal bleeding, and I am not sure if I consider this my menstrual cycle. It is now more than 2 weeks and I am still bleeding.

Painful menstruation cycle directly after (4days earlier than I should?ve received it), longer than usual menstruation cycle (8 days instead of 4 days), and different texture (thicker and sticky)

The next day I started my period. Normally not a weird occurrence, but it was 4 days early and a lot heavier than what I'm used to. I've never taken any feminine birth control and have always had a very, very regular and reliable period. But this go around I was experience heavy bleeding and cramps right away rather than a few days in. Even now after five days, I my period would normally be tapering off and the blood would be changing to light pink in color. Yet, I'm still experiencing bright red blood.

Irregular menstrual cycle. Breakthrough bleeding/spotting starting 3 days after vaccine. Bleeding comes intermittently & is randomly heavy then stops. Seems like I?m on my period every 2 hours or so. Not due for the start of period for 1.5 weeks from today. Usually VERY regular and have never once had spotting before. 0% chance of pregnancy at the time of vaccine or currently.

A week after receiving my vaccine I noticed vaginal spotting and thought I was getting my menstrual cycle. That spotting turned into heavy bleeding and hasn't stopped for 3 weeks

Within 7 hours of receiving the vaccine, I started what I thought was my second period of the month. I had just finished a period 12 days earlier. I am usually 35 - 42 days between periods so this was VERY unusual for me. I had my normal period pre-vaccine Jan 4 - 9 then 7 hours after the vaccine started bleeding again from the 21-25 of January. Then again on Feb 4 - 9. I got my second vaccine while bleeding. Then again started to bleed on Feb 21 - 25. I had a doctors appointment at the end of February. I got an annual gyno exam as well as a ton of bloodwork was taken to check everything out. I was told to continue to monitor the bleeding and if it didn't stop we would do a pelvic ultrasound. Well, it didn't stop so we did and it came back normal. I had a mostly normal March with light bleeding. I thought perhaps it was getting better but no. I have had two periods in April. In fact still bleeding on round two and this is my 6th day bleeding. Periods or irregular bleeding was April 12-17 and then again on April 24 - 29 (still happening and it's the 29th). This is very scary to me as no doctors can help.

My period this month was April 15th-April 21st with no additional spotting/bleeding after the 21st. Within 24 hours after the first vaccine, I was bleeding enough to need a pad changed every few hours. I experienced all symptoms that I typically have during my period - uterine cramping, lower back pain, & a loss of appetite. After 48 hours, the bleeding has stopped and I?m no longer having symptoms similar to a period. I?ve had an IUD for over a year & have never had break through bleeding or spotting. Additionally, this was heavier than slight spotting - it felt as if I had started a new period.

I have had a very predictable, regular, 29-day period cycle for the past 1.5-2 years. I track my periods every month. After receiving the vaccine, I got my period 5 days early and had heavy, painful period symptoms that are normally mild for me. I normally do not get nauseated on my period, but feel very nauseated this time. I did not change anything in my diet, supplements, activity, or stress levels since my last period. The only outlier has been the vaccination.

Chills, fever, muscle aches starting approx. 18 hours after shot. Resolved 36 hours after shot. Unexpected menstrual bleeding starting approx. 24 hours after shot - medium flow and then spotting. Normal period had ended 3 days prior. Resolved approx. 48 hours after shot. Have been using Liletta hormonal IUD for 4 years.

Missed menstrual period ongoing, last cycle 3/24/21 with multiple negative urine pregnancy tests. Dizziness and blurred vision also experienced shortly after administration.

I ended my last period on April 20th. I got my first Pfizer shot on April 27th. I got my period on May 7th, over a week early than I should have and it is very heavy bleeding, more than normal, with severe cramping and fatigue. I am not on any form of birth control, and I am not sexually active. My period has never come early this far in advance. I also wasn't under any particular stress during that time period, or experiencing any unusual sleep patterns. Today is May 10th and I am still bleeding heavily. I may add another entry if the bleeding goes on for longer than my normal period. I also will be visiting my obgyn this afternoon.

Severe rash in left underarm, requires topical steroid. Menstrual cycle 3 days late. Rash appeared within a couple days of second dose. Has not gone away.

Period started day of the shot (Sat), heavier and more cramping than usual, 1 week earlier than expected which is unusual (was not stressed leading up to appt) Fever starting Saturday night, as high as 103, dropped down to 100 at the end of the second day, still ongoing Headache Sunday and Monday Soreness on Saturday, mostly went away on Sunday, but I spent a lot of time swinging my arm around

Within 24 hours: Fever over 100°F, chills, vomiting (possibly with blood), coughing, runny nose, body aches, fatigue, menstrual cramping and discharge, dizziness, migraine After 36 hours until now (68 hours later): Shortness of breath, fatigue, body aches, migraine, severe menstrual cramping and discharge, dizziness, coughing

Have had a steady period since at least the 2nd shot. The period started very heavy with clots, and has been thin but steady for the past 2-3 weeks.

No period after 1st shot, after second shot period came a week later. Heavy flow every day lasting over a week and cramps. Usual cycle is 28 days and period lasts 2 days very light. This cycle was 44 days.

Heavy menstrual cycle with blood clots, bright red color, extreme cramping in pelvic area as well as shooting pain in both legs. Started on 5/13 with heavy cramping, cycle started on 5/16. Bled two days longer than normal. Still experiencing cramping on 5/20/21

Prolonged menstrual bleeding (24 days): stopped only after my PCP prescribed Provera That said, would still get the vaccine if I had to do it over.

I have not menstruated since getting the Covid-19 vaccine. I have not had sex that would result in pregnancy and I have taken 2 pregnancy tests (even though there is no way that I am pregnant). Both pregnancy tests are negative. I have not menstruated since getting my second vaccine.

My symptoms where very mild: fatigue, mild aches (especially in my upper body and including my eyes). OTC pain medication easily reduced my mild symptoms. 48 hours after the 2nd vaccine, I started spotting and experiencing strong menstrual cramps for about 15 minutes. During this time, the cramps felt very severe - a 9 out of 10 on the pain scale. I almost felt like I might throw up from the pain. But then it subsided to a 5 and took Midol and applied heat. The cramps returned at 5:00 pm. Date of last cycle was approx 5/23. I don?t spot, so this stood out to me.

Patient states she took the 2nd dose on the same day as the first day of period and had slight clotting on the last day. She then missed 2 pills in started spotting again.

Significantly stronger cramping during my next menstrual cycle. Also more heavy bleeding during menstrual cycle.

My period was supposed to start the day I received my first shot. It has not started since I received the first shot (and I have since gotten the second shot as well). I have had intense cramping but my period has not come back since getting the vaccine. I don't think this is life-threatening, but I am concerned that nobody seems to know what is going on. I have confirmed that I am not pregnant.

I found out I was pregnant a couple weeks after receiving my final COVID vaccine. My last menstrual cycle was on 3/9/2021 and I had a positive pregnancy test on 4/8/2021. My last pfizer vaccine was given on 3/31/2021. My estimated date of delivery was 12/15/2021. I had a pre-natal visit at approximately 10 weeks when things appeared normal. Subsequently started passing brown mucus (5/22/2021) and then bright red blood with clots (5/28/2021). Went to the hospital and no cardiac activity was detected on ultrasound and I subsequently had a D&C on 5/29/2021. I was 11 weeks +3 days (based on LMP) when no cardiac activity was detected.

Pregnancy history: 3 full term LIVE pregnancies No previous miscarriages Due date was December 7th, 2021 Genetic/chromosomal blood testing was performed at 10 weeks and 2 days gestation on May 13, 2021: confirmed gender was male and everything was normal and healthy. Ultrasounds were performed both at 9 weeks gestation and at 13 weeks gestation (genetic/chromosomal screening) and everything was normal and healthy. On June 24th (16 weeks 3 days): was seen in ER due to upper abdominal pain. Was diagnosed with a miscarriage that occurred around 14 weeks gestation. Procesure (D&E) to remove fetus took place June 29, 2021. I lost over 3 pounds of blood and almost died following procedure.

I reacted to the first vaccine, the health department took me to the hospital. I was monitored immediately having trouble breathing, took Benadryl, used my inhaler but then after that I started having problems to allergens that were not a problem before. I ended up needing an epi pen, I started to have trigeminal episode where it started to have them everyday. I also had fibromyalgia every day, pain scale 7 out of 10 on VAS scale. I ended up going to the doctors where they tried different medications. I started getting heavy periods and my birth control medication I had been out for 7 years, stopped working. I have lost a lot of weight, about 40 pounds. I was having migraines pretty much every day. I also started to get on one side of my face, left side. Then the same started happening to my right leg. I started to have vision problems, where me the sides of my eyes would go black and cracks in my vision. I went to the neurologist, ophthalmologist and no one had been able to figure out what is wrong with me. I have not been able to work for months. I was pretty active before the vaccine, I worked with a cancer institute for kids, but now I could not perform my daily activities, got so sick all the time. I had to move back with my parents. I still have pain a lot of the time, I do not have Covid and my symptoms have been pretty horrible since receiving the vaccine. I've had blood panels done, eye exams, MRI of the brain and pap smears but the exams are all negative and can not find the reason to my symptoms. No spinal tap yet done. Also my asthma is not under control and I get winded when going up a flight of stairs. I do not have the lot# to provide today.

My menstrual cycle has changed since receiving the second dose of my vaccine. It went from super heavy and 5 days to extremely light for 2-3 days max. 7/12/2021 I was experiencing hot and cold flashes and cramping. I?m uncertain if this was related.

Menstrual period never came. Not pregnant. Not sure if it?s related to the vaccine but it usually shows up on time so thought it could be worth reporting.

The last day of my period was March 1st, and I got bleeding just like the period one day after the vaccine (March 6) I usually have my period 3 weeks after last day.

**8 weeks pregnant, estimated due date 10/25/2021. 2nd pregnancy ** I had vaginal spotting. I went to see my Midwife, they had me do an ultrasound and drew some labs. I went back two weeks later and had blood drew again and everything came back normal. My Midwife told me she had a lot of people call and tell her they were spotting after there vaccine.

Immediately following vaccination, started having itchy tongue, ears and mouth. Rash emerged on left chest and shoulder with muscle pain. Left arm became numb, rash at injections site, migraine, numb lips and mouth. Persisted and progressed to vomiting and diarrhea, tachycardia and tachypnea. On 1/14, petechiae around both eyes, widespread muscle and joint pain, tachycardia and tachypnea persist, unable to lift left arm, itchy face, nose and throat. 1/15 Tachycardia persists, migraine, diarrhea, sudden onset vaginal bleeding. 1/16 elevated blood pressure, tachycardia and tachypnea, found unresponsive in bed by my husband and taken to the emergency room.

Early period, migraines. Know three others who got their second period of the month from their vaccines.

A 100+ degree fever developed approximately 36 hours after vaccination and lasted for 8-12 hours. I developed extreme fatigue that lasted for 48 hours after the fever began. Approximately 36-48 hours after the fever began, my period started, and I had severe cramps, blood clots, and bleeding that were notably abnormal for me. I am on birth control and have very minor, if any, withdrawal bleeding.

Period is over 1 week late (going on 41 day menstrual cycle). Period is always between 28-33 days. Not sexually active so no chance of pregnancy.

Began a heavy period December 17th in the early morning. Period was two weeks early, heavy, and painful. Every two weeks since the first vaccine I have had a period. Got hormones checked, labs, pelvic ultrasound. All normal. Four months later I am still bleeding.

Began menstrual spotting the next day and heavy bleeding the following day. I just had my period 2 weeks before that. My period comes every few months because I am on Nexplanon. I haven?t bleed this heavy since I was a teenager.

Missed period. Menstrual cycle very regular prior to the vaccine, occurring every 27-28 days. Now two weeks late; no pregnancy.

2 days after vaccine patient began to heavily menstraute. Patient has extremely irregular and light periods that she takes medication for. She went almost 80 days without a period before she had one approximately 2 weeks before the vaccine. PMS symptoms started the day after the vaccine, including tender breasts. Patient also had a fever, chills, congestion, and a headache. Patient experienced severe cramping, nausea, and extremely heavy bleeding.

Within 5 minutes of receiving the vaccine I started to experience hot and cold sensations throughout my body, it continued for about 20 minutes and then it subsided. I was due to start menstruating the day I received the vaccine but it did not come. My cycle has been very regular and my period always comes on time but it still hasn?t come. I have all my typical PMS symptoms and multiple negative pregnancy tests.

I experienced an early menstrual cycle after the first shot with very light flow. Two weeks after the second shot, I am experiencing very heavy flow compared to normal, and had moderate period cramps on the first day of menstruation. This is atypical as my cycles are usually cramp-free with moderate flow. I also experienced additional fatigue on the first day of my cycle.

I am breastfeeding. My milk supply decreased dramatically. My period also started. I haven't had a period since September 2019. I believe they are related.

Developed acute-onset, sharp right pelvic/groin pain radiating to right groin and flank the day after receiving first Pfizer COVID vaccine. Non-contrast CT abd/pelv revealed right ovarian cyst which resolved on follow-up vaginal ultrasound 1 week later. Within about 2 days, the sharp pain progressed to burning neuropathic-type pain across the pelvic/pubic region and down bilateral inner thighs to knee level. Pain was constant. After 10-14 days, the pain transitioned from burning sensation to sensation of feeling cold (both on skin and deep tissues) that would feel normal to the touch. It is symmetric on both sides and begins at the level of umbilicus and involves both groins and medial thighs. Symptoms worsen with sitting or standing up for prolonged periods of time (and become more noticeable/bothersome) and as the day progresses. About 2 weeks later, the severe burning pain progressed to include bilateral buttocks and outer thighs as well. MRI brain/cervical/thoracic/lumbar spine largely normal (tarlov cysts S2-S3, small left disc protrusion C5-C6). CBC, BMP, TSH, B12, B6, lyme titer, ESR normal. Currently being treated with gabapentin 300mg TID.

Delay in menstrual cycle. Due 4/5/2021. As of 4/12/2021 still has not occured. Typical PMS symptoms and negative pregnancy test

Soreness at the injection site and elsewhere in the body, Fever of 101.4, headache, breast tenderness

menstrual cramping (severe and 1 week before cycle); extremely heavy flow and pain; increased length of period (10 days - previously 4 days). Worth noting, I had the Paragard IUD put in on March 15th. I was told this would effect the cramping but not the length and flow.

Menstrual spotting during week 1 of cycle (1 day after vaccine) Strong menstrual cramps (1 day after vaccine) Additional side effects (1 day after vaccine): Fever 103 F Chills Body aches Headache Fatigue

It jumpstarted my period start date. Broke out with acne. Mainly wanted to record this so that there's more a trace on side effects.

Nausea, abnormal menstrual bleed outside of normal cycle, headaches, body ache, chills, fatigue, brain fog

My menstrual period was due to start on 4/14, 12 days after receiving my 1st dose of the COVID vaccine. I still haven?t started my period, and have been having increased anxiety and severe hormone swings. I?ve taken two pregnancy tests and both were negative. My OBGYN was unable to confirm a relation to the vaccine, but said it?s a possibility.

Early period Feb, Early and extremely light period March, late by a week period April ( multiple negative pregnancy tests)

Pregnancy miscarriage -- 3.5 weeks pregnant at the time of vaccination and experienced a miscarriage one week later (at 4.5 weeks pregnant)

Amenorrhea - Lost Period - No bleeding Have not had a period since 02/28/2021 I was vaccinated on 04/01/2021 and was supposed to start my period on 04/03/2021. It never came. I am not pregnant. I am currently in birthcontrol and have never missed a period. I am unsure if the vaccine affects birthcontrol or fertility or how long it will cause amenorrhea. I was told to ?wait another month and see what happens.? This was not caused by stress, diet change, weight gain, pregnancy, etc. The only thing that changed in my life was the vaccine. You need to investigate this association with blood clotting in women of childbearing age.

Spotting, bleeding, clotting, and cramping not associated with a regular menstrual period, lasting for two weeks.

My menstrual cycle came a lot heavier than it has ever been, including large blood clots. Additionally, my premenstrual symptoms were much more painful and intense

My menstrual cycle was late by 2 weeks and I had the most *severe* cramping of my life. It began at 5:00 am with low to moderate levels of cramping. By 6:30 am I was fully awake and waiting for the local CVS to open at 8 am so I could purchase ibruprofen. (I NEVER have to take ibruprofen due to cramping). I ate food before I took 200 mg - an hour later my symptoms had progressed to include doubling over in pain and nausea at which I ate a little more food and took 400 mg more (total 600 mg). At 600 mgs my symptoms abated enough for me to eat a small breakfast (10 am). 4 hours later the nausea and severve doubling over with pain cramps returned which is when I ate more food at took another 600 mgs of ibruprofen. I went to bed at 7pm that night (usual bed time is 9:30) I used ibruprofen to manage my symptoms all that first day ? the next day I was exhausted from feeling so beat up the day before but thankfully no more cramping or nausea. Today is day 3 and I am feeling back to myself. I would just like to reiterate that I have NEVER in my life had a period this severe in cramping or nausea.

About 24 hours after I received the 2nd dose of Pfizer a lump (tennis ball size) appeared on my left breast of opposite arm of injection. The lump was not going away after 7 days so I reached out for; nothing could be explained for the lump that still had the same size, shape, and constant pain.; This is a spontaneous report from a contactable other HCP. A 29-year-old non-pregnant female patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Batch/Lot Number: Unknown, Expiration date: Unknown) via an unspecified route of administration in the left arm on 25Jan2021 16:15 as SINGLE DOSE for COVID-19 Immunization.

On 25Jan2021 03:00 about 24 hours after she received the 2nd dose of Pfizer a lump (tennis ball size) appeared on her left breast of opposite arm of injection. The lump was not going away after 7 days so she reached out for medical help and after multiple antibiotics, ultrasounds, and mammograms, nothing could be explained for the lump that still had the same size, shape, and constant pain. It was now day 25 of this painful lump and she wanted to reach out to see if there were any cases related. She had not any injury, diet change, allergic reaction that could had caused this other than getting the 2nd dose of the Pfizer vaccine. She needed help and doctors here refused to believe it was related. The patient underwent lab tests and procedures which included sars-cov-2 test: negative on 28Jan2021.

Typical menstrual cycle is 31 days. Since the 2nd vaccine my cycles have been 29 days, 27 days, and 21 days.

Delayed menstruation by 7 days, causing severe menstruation pains (cramps) that have never been experienced in any prior menstruation (15 years). Menstruation has also been paired with a migraine (light and noise sensitivity, severe head pain) - I have NEVER experienced a migraine like this before (no history of having migranes).

Menstrual issues: excessive bleeding and cramps (more then ever experienced). Menstrual period lasted 3 days longer than typical. This has occurred in both cycles following the vaccine injection.

experienced bleeding last night, when she is not even scheduled to have her menstruation yet; Vaginal bleeding; dizziness; waves of nausea; tiredness; chills; feels hot and cold a lot/hot flashes or cold a lot; had cramps similar to that of menstrual cramps; felt like she had a fever; This is a spontaneous report from a contactable consumer (Patient).

Last night (14Apr2021), she said she had cramps similar to that of menstrual cramps. She said she has not had cramps ever since she started being on an Intrauterine Device (IUD) and birth control. Consumer also said that she experienced Vaginal bleeding last night (14Apr2021), when she is not even scheduled to have her menstruation yet. She wants to know if this is a normal reaction to the vaccine, and if it is normal that she is still having the symptoms even after almost 7 days since receiving the vaccine. Caller states she gets dizzy a lot, waves of nausea, and felt like she had a fever, hot flashes or cold a lot. Had to call out of work on the weekend. Last night was really weird for her, was having cramps, like menstrual cramps, has an IUD and takes birth control and went to the bathroom and she was bleeding, even if she was supposed to have her period it wouldn't be the time she was supposed to be having it, called her Gynocologist to let them know.

Outcome of the event was unknown. No follow-up attempts are possible. No further information is expected.

My first COVID vaccine injection was December 19, 2020 (10-month postpartum) and my 2nd was January 9, 2021 (11 months postpartum). Symptoms started 3 months after my 2nd vaccine (04/11/21). Extremely heavy irregular periods in between my normal periods. Menstrual cycle is typical 28 days. I am having very heavy periods starting 13 days into my cycle that lasts 7 days. Also having periods when I should be at the 28th day of my cycle. So essentially I'm bleeding every 13-21 days. I am on Junel birth control which I started (04/24). I was on Lo Loestrin at the time of the vaccines.

Sore arm starting the evening of the first and second shots and then fatigue the next day. These side effects are not concerning and not a big deal. I did want to report that my menstrual cycle had a ?double peak? ovulation and a resulting very late period (3 weeks late). I chart my cycle extensively and this has never happened to me before; the only change during this cycle was the second covid shot close to my typical ovulation time. I know that stress and illness can cause a double peak (meaning ovulation is delayed), so I believe this shot may have been interpreted by my body as an illness as I was not under stress or sick at this time. I did not have an issue with my cycle during the first shot. I felt this was important to report as I had only heard of women having early or very heavy periods after the shot.

Menstrual periods following the vaccine have been more intense: higher volume of blood lost, more painful cramping, increased breast tenderness and swelling, increased duration of period by roughly 2 days.

After my first vaccine, I got my periods one or two days early, and after my 2nd dose, my periods are delayed for more than 25 days now... Experienced severe cramps in between...

Period is a week late. It?s never irregular. I was perfectly healthy before this. There is no reason for my period to be late.

I had had my period when I got my first shot, around 2/27/21. I thought it was weird when two weeks later, I started to get "another" period, when I'm on birth control and my period is always normal. It started early in the morning on 3/9/21 which was my birthday. I started having such horrific cramps, that they felt worse than contractions. Eventually, I was losing so much blood, that I was worried if I stood up from the toilet, that I would pass out. I waited until my Dad came home around 4 p.m., and had him drive me to the emergency room. I was in horrific pain, losing a lot of blood, etc. Eventually, I went to the bathroom, and passed what was a fist size piece of tissue. It looked almost like a clear/bluish flesh, the size of an old rubber coin purse, with a thick and malleable consistency. The doctor at the emergency room never did an ultrasound, vaginal exam, etc., but said that I had a "dysfunctional uterus". This had never happened to me before, and I had never passed this type of tissue. The fact that it happened exactly 2 weeks after getting my first shot was weird. Then, 2 weeks after my 2nd shot, it happened again. The same thing. I had a period that I was not expecting, and ended up passing a fist size piece of tissue. I had contractions all day, almost passed out from the pain, until that was passed. I'm not sure what is going on, but it definitely seems related.

My period was a week early and has been on going since June 24. It is now july 5, I am concerned. My period is usually normal and only 4 days. I am not taking birth control. I got my period 3 days after my second dose of Pfizer vaccine

I received my first dose of the Pfizer vaccine on June 16th, the day after I started menstruating. My period did not end until July 3rd resulting in 19 days of bleeding.

Two weeks early menstrual bleeding; Two weeks early menstrual bleeding, including clotting and mucus; two weeks early menstrual bleeding, including clotting and mucus accompanied by cramps; Fatigue; headache; body pain; This is a spontaneous report from a contactable consumer, the patient. A 29-year-old-non-pregnant female patient received her first dose of BNT162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; lot number: EN6208) via unspecified route of administration in the left arm on 13Mar2021 at 15:30 (at the age of 29-year-old) as a single dose for COVID-19 immunisation. The patient medical history included autoimmune disease. The patient was allergic to morphine, gluten and dairy. Concomitant medication included thyroid (ARMOUR THYROID) medication. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. On 23Mar2021, the patient underwent nasal swab test and tested negative for COVID-19. The patient was not diagnosed with COVID-19 prior to vaccination. On 14Mar2021, the patient experienced two weeks early menstrual bleeding, including clotting and mucus accompanied by cramps, fatigue, headache, and body pain lasted for more than 7 days. The patient did not receive treatment for the reported events. The events resulted in the doctor or other healthcare professional office/clinic visit.

My period started May 28 and my second vaccine was May 29. I found out I was pregnant June 27 and had a miscarriage on July 12. Not sure if this is related but my OB wanted me to report it.

The second Pfizer shot caused me to have a second period in the month of April. The period occurred around the time of ovulation for me (4/17/21). We were trying to conceive at the time. We managed to become pregnant that month despite the confusion with two periods and not knowing if my ovulation schedule would change. I had a positive pregnancy test on 5/7/21. By 5/20/21 I started bleeding. I had a hospital removal procedure (MVA) completed on 6/11/21 due to a miscarriage during this pregnancy.

I received first dose of Pfizer vaccine on 4/12/2021 and second dose of Pfizer vaccine on 5/14/2021. At the time of first dose, I was not pregnant but we were actively trying to become pregnant. At time of second vaccine, I was pregnant (possibly 1-2 weeks along). I did not know I was pregnant. At my regular first check up on July 6, 2021, I went in to confirm pregnancy with my OGBYN. An ultrasound confirmed I had a blighted ovum, which is a type of miscarriage that the body does not recognize on its own. I did have a surgery to end to miscarriage since my body did not do it naturally. I wanted to report this happening in case it was significant since the timeframes of receiving vaccine and pregnancy were very close together. I know tests on the safety of this vaccine have been very limited and wanted to offer my experience in case it is relevant. Thank you,

After receiving the first covid vaccine on 12/18 in the morning, I had my period about 12 hours later. Throughout my life, my periods are very regular and typically last 6 days. But after the vaccine, my period never stopped. I am still currently bleeding. I've seen a doctor for it and they said its a hemorrhagic corpus luteum cyst. For now the doctor isn?t too concerned, but it?s unusual for my body to be going through this.

The day after the first dose I began experiencing pre-menstrual symptoms including heavy cramping. I also began shedding from my vagina small clumps of skin, maybe the size of a pea. I started my period about a week later and experienced much heavier flow than normal in a much shorter period of time. My second dose was received on 01/20/21 at 10am at the same facility. The day after I began similar feelings of cramping and experienced very heavy, opaque white discharge from my vagina with a couple of pea sized clumps of what looked like my vaginal wall the day or two after, but then none at all. I continued to see this odd discharge until today (01/31/21). Neither experience was at all painful, but it was very alarming.

More than normal vaginal discharge after the first dose of the vaccine. Bleeding from vagina (possible period) 2 days after the second dose on 2/12.

Extreme headache and body ache after vaccine. 36 hours after I received an early menstruation that is not expected for another 2 weeks. I am very regular, this is out of sync.

1/8 vaccination 1/9 I woke up with severe HA, muscle aches, and fatigue. That evening I got chest pains. 1/10 CP resolved. Everything resolved. 1/17 positive pregnancy test 1/22 miscarriage. First pregnancy. 2/10 finally able to see dr.

Therapeutic measures were taken as a result of miscarriage included misoprostol (CYTOTEC). Information of lot/batch number has been requested.; Sender's Comments: The limited information provided precludes a full clinical assessment of the case. Considering the product-event temporal relationship, a causal association between the reported 'miscarriage' and the administration of bnt162b2 cannot be completely excluded. Case will be reassessed once with additional information. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees, and Investigators, as appropriate.

A few hours after the vaccine I started feeling fatigued and having chills. I was so tired and sleepy I slept almost all day for the first 48 hrs after. Developed fever between 100.5-101 which lasted about 18hrs which did require me to have to call into work the following day. 2/3 I developed swelling and pain in the lymph nodes under my right arm and breast. The swelling subsided within 4days but I still have some tenderness to date. I took tylenol and ibuprophen for the first 48 hours to help with all the symptoms.

Found out pregnant in between doses 1 (12/21)and (1/11). Lmp 12/13/2020. Was informed on 7 week ultrasound the fetal heart rate was low and Miscarriage likely. Miscarriage 2/4/2021.

I suffered a miscarriage at 7 weeks 4 days. Miscarriage occurred on 1/23/21. Vaccination 1 was on 12/26/20 & Vaccination 2 was 1/12/21

I am unsure if this is related but thought I should report it because it was highly unusual, but: My menstrual cycle began at around 12:30am on 03-19-2021. There was some bad cramping as is usual for me in the first 24 hours. I was able to function normally enough until about 9P (on 03-19-2021), at which time I began experiencing debilitating cramps and muscle spasms that made it difficult to walk or move. I felt lightheaded and like I was going to pass out (which has never happened related to my period before). I got in bed and this persisted until moving at all brought me to tears. I have not been in this much pain from cramps and muscle spasms in over a decade. And never this prolonged and intense. I was unable to sleep until about 4:30am, managed to sleep for a few hours, had to see, and now I'm here filling this out before I attempt to go back to sleep. My pain at the moment is high, but similar to what a normal "first day of cycle and it's bad" day would be for me. Before this, though, was 8 hours straight of some of the worst pain I've ever felt in my life. I felt it important for me to make a formal report in the event that adverse effects surrounding menstruation were common for others and in case this does not subside. I am thinking it will like the initial muscle aches after receiving the shot.

Received 2nd dose of covid vaccine at 11 weeks, 6 days. Had follow up normal ultrasound at 12 weeks, 2 days. Missed miscarriage noted at 15 weeks, 1 day. Last measurement of baby noted to be 12 weeks, 6 days. Closely monitored during first trimester with no abnormalities noted. Normal ultrasound at 12 weeks, several days after baby stopped growing with fetal demise at some point there after

Early miscarriage; This is a spontaneous report from a contactable other health care professional (Patient). A 30-year-old female patient (pregnant, last menstrual date 19Jan2021, Delivery date: 26Oct2021, Gestational period 4 weeks) received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number EL9269), via an unspecified route of administration on right arm on 19Feb2021 at 15:15 at the age of 30 years old at a single dose for COVID-19 immunisation at hospital. The patient's medical history included rheumatoid arthritis. There were no known allergies. Concomitant medications included prenatal vitamin. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. The patient received other medications within 2 weeks of vaccination. The patient experienced early miscarriage on 01Mar2021. No treatment was received in response to the adverse event. The patient was not diagnosed with COVID-19 prior to vaccination. Since the vaccination, patient was not tested for COVID-19. The patient was recovering from the event. No follow-up attempts are possible. No further information is expected.; Sender's Comments: Pending the limited information on clinical course, the company does not attribute the event early miscarriage to BNT162B2. The detailed document of pregnancy, relevant risk factors, status of rheumatoid arthritis are missing for a medically meaningful assessment. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to RAs, Ethics Committees, and Investigators, as appropriate.

Vaginal bleeding/irregular bleeding; bloody noses; spotting; This is a spontaneous report from a contactable Nurse (patient). This 30-years-old female patient received at hospital bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE), dose 1 administered in Arm Left on 17Feb2021 (Batch/Lot Number: EM9809) as SINGLE DOSE, and dose 2 on 07Mar2021 (Batch/Lot Number: EN6206) administered in Arm Left as SINGLE DOSE for covid-19 immunisation. Age at vaccination 30 years. Medical history included ongoing spotting (she has had her tubes tied in the past /She continued to have spotting even after the period was over). The patient got 1st dose on 17Feb2021 and developed Vaginal bleeding, bloody noses. She said she was having a period every 2 weeks, and "spotting" every other day. The she got 2nd dose on 07Mar2021, and experienced nose is bleeding and vaginal bleeding again.Then it was added she completed both; and keeps having irregular bleeding. she received the first dose of the Pfizer COVID 19 vaccination 17Feb2021 at an unknown time in the left arm. On that day she noticed irregular bleeding, spotting. Mentioned she has had her tubes tied in the past and so she called her gynecologist who made an appointment for her. Then she got her regular period two weeks later to she cancelled that appointment. She continued to have spotting even after the period was over. She mentioned this to her gynecologist twice and he said to wait and see. She received the second dose 07Mar2021 at 16:50 PM in the left arm. She noticed today on 10Mar2021 she was having vaginal bleeding and spotting with bright red blood and also a nose bleed. Mentioned she also noticed blood with sex. She was concerned and plans to contact her HCP next because her brother had osteosarcoma at 16 years old and she has a cousin who had thrombocytopenia. Seriousness criteria provided -Other medically important conditions. The outcome of the events was not recovered.; Sender's Comments: Based on available information and known drug profile it is unlikely that the reported "vaginal bleeding, spotting with bright red blood and nose bleed" were due to bnt162b2. These are probably intercurrent medical conditions. Case will be reassessed of additional information is received. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees and Investigators, as appropriate.

In my first dose, I am having fever, headache, body aches, nausea, dizziness and bleeding from my menstrual cycle has increased a lot.

Severe joint pain, especially in knees that woudlnt go away, Amenorrhea or loss of period after first shot

Within a few hours of vaccine administration, my menstrual cycle ceased to exist. At the time of the vaccine around noon I was on a heavy flow of day 2 on my period. I was changing tampons at my usual rate of every 4 hours. By 8pm the same day of administration, my period ceased to exist. I no longer needed to use tampons or pads at all. My menstrual cycles are consistently at LEAST 5 days long, not 2. Will follow up with my regular ob/gyn.

Spotting as if beginning a menstrual cycle after Pfizer vaccine dose one. I have an IUD so I do not menstruate. No other issues besides noting spotting and increased vaginal discharge the day following vaccination. Symptoms lasted one day.

Mentrual bleeding completely out of cycle. I track my cycle and was not due to start menstruating for at least two weeks. Bleeding and symptoms began about five hours of receiving second dose. The bleeding is not temporary, it seems as though the shot has initiated an early cycle.

Patient had two previous live births and two spontaneous abortions at 10 and 8 weeks prior. Reported lack of fetal movement in the last few days (not quantified). Provider note ruled as a pregnancy loss at 19 weeks of gestation.

Abnormal menstrual bleeding (currently have been spotting for 16 days). Petechiae on hands for first 24 hours after vaccine.

Had an early, off-cycle period that was heavier than usual. It started about a week after my first shot. It was about 2 weeks early. Prompted me to go to the OB/GYN for an ultrasound and exam because it was so out of the normal for me and my body.

The worst period I had to years. I got my period a week and a half early , it started the morning after I got my vaccine. I was bleeding through plus tampons in 2 hours. I went off north control 1 year ago and have no other hormones in my body.

I was 7 weeks pregnant and assured by everyone that it would be safe to get vaccinated. I have had one healthy pregnancy 10 years ago. I found out I miscarried yesterday (4/13/21). I can?t help but feel that it was related to the vaccine & am devastated. I don?t want any other mothers to experience this if it was indeed related so I am reporting this.

My period began 2 weeks earlier than it should have and with an EXTREMELY heavy menstrual cycle, which is vastly different from my normal menstrual cycle. I am also having extremely cramping and fatigue.

8 days after vaccine - Extreme menstrual cramps for 2 days 14 days after vaccine - A period that was 7 days early and only lasted for 2 days

I had my first dose of Covid 19 Pfizer vaccine on the 5th of April, 2021 at 1pm. I had sore arm and was fatigued which was expected. However, the day I had my vaccine was also the day my menstrual cycle started and just to assure myself I informed the pharmacist and asked if that was okay and they said it shouldn?t be a concern. I was doing fine until toward the end of day 3. I was expecting my period to stop as it always does on 3rd day but I started bleeding heavier that day there after. It didn?t worry me much until I started discharging huge blood clots as big as an apple 2 times every after 30 mins from that moment. I rushed to the ER later that night(still bleeding heavily with blood clots every now and then) but I was not admitted since my vitals and the blood counts were normal at that moment. I went back home and hoped the bleeding would stop but again with on pain or fever what so ever I kept bleeding all day. This is my 5th day of bleeding. Then on Sunday morning, I still kept bleeding heavy and I was too weak that I went back to the ER again. This time , (day 6) I got admitted because I have had lost a lot of blood and I needed blood transfusion. My HB dropped from 11.3 to 6.7 and it went further down to 5 something. I got 3 units of blood transfusion in the ER. They did ultrasound, CT scans(with and without contrast) and still couldn?t figure out the cause of the bleeding. My uterus showed no problems but my body was not even responding to Tranexamic acid to stop the bleeding. So the doctor proceeded with an angiogram and did an emergency uterine artery Embolization to stop the blood supply to the uterus. The bleeding stopped there after and I started regaining my vitals. However, the cause of the bleeding still remains unknown.

Short term: Fatigue (4 days), debilitating fever and chills (2 days), white and purple extremities (3 hours), severe chest/abdomen pain and pressure (1 day) - nearly went to ER Longer term: headaches (1 week), halted menstrual cycle with no pregnancy (1 week late on clockwork 26 day cycle with no stress or lifestyle changes.)

MISCARRIAGE- Conceived and got pregnant March 28. Received 2nd dose of Pfizer vaccine April 2. Found out I was pregnant April 14th, and confirmed it with blood test taken April 15th. HCG levels at 57, putting me at around 3 weeks pregnant. Started bleeding April 18th and doctor confirmed a miscarriage is taking place.

Menstrual cycle outside of normal timeframe (birth control has me go 3 month no period, and the last week of that 3 months a very light cycle) Roughly the day after the first injection on March 24th I began an out of norm cycle that has been extremely heavy and has been ongoing for a month now. There has been no reprieve in this period since it began and after speaking briefly with my doctor she requested I bring these symptoms to the VAERS website. In summary- Symptoms-Excessive bleeding/length of menstrual cycle ongoing for 3+ weeks.

Early menstruation - period started about a week early (was on last week of active pills in 28 day pill pack). No heavier/lighter than usual.

My period is 6 days late. This is not normal for me and nothing else has changed in my life since my last menstrual cycle. My period is incredibly predictable and it is physically impossible that I am pregnant. I took a pregnancy test just as an extra precaution and it was negative. I have been seeing news reports of women indicating that their cycle was disturbed by the vaccine and until it happened to me, I questioned the veracity of these claims. However it has now affected me and I believe that the vaccine is the cause. I do not know if this constitutes an adverse event but since it is a side effect that is not listed on the CDC website, and since it is affecting my physiology, I believe that it should be considered seriously.

Fatigue: onset 8pm, duration 2 days Cold sweats: onset Sunday night 9pm 1day after the vaccine. Lasted through the night Brain fog, started Sunday morning and lasted until Thursday of the same week approximately 4-5 days. Late ovulation, ovulated a week later than normal mental cycle also late. Expected dates 4/10-4/15; actual 4/19-4/21 expected period 4/26 Arm soreness, swelling and redness at the injection site and upper arm/shoulder area. This started immediately after the vaccine, the next day it was swollen and red which lasted for 1 week.

I received the first dose the the pizer vaccine on december 18th and did not know I was pregnant at the time. A couple weeks later I found out I was pregnant and due date was September 7th. Hence, my conception was likely within a week of receiving my first dose. We later found out our baby had turners syndrome and have since lost the baby. Obviously it is unclear the cause but I wanted to report it .

Menstrual spotting/bleeding day after receiving first vaccine dose, spotting still currently lasting following week. Spotting started 1.5 weeks before next period

Fever; aches; severe arm pain; skipped menstrual cycle completely; chills; This is a spontaneous report from a contactable consumer (Patient).

Fever of 101 for 12 hours Skin sensitivity: painful to touch, constant needles Shortness of breath Difficulty to move without getting winded Muscle aches all over except for at injection site for 5 days Three weeks later: I am still feeling needles in my back, I still have shortness of breath, anxiety, period like spotting before period is due, sudden chills, and stiffness in muscles that was not there prior to vaccine.

Late period. My periods are an average of 26-27 days. It has been 30 days now and no period. Not pregnant. The only difference in lifestyle this menstrual cycle was the vaccine.

First cycle after giving birth 9/11/2020 happened a day before taking the vaccine. Once I received the vaccine, my cycle stopped completely. Also the lower back pins and wrist pains as a result of taking the epidural in 9/2020 which subsided 12/2020 came back the day after receiving the vaccine.

Fatigue, pain in left shoulder, heavy menstrual bleeding 2 days after the shot despite the period just ended 1 week ago.

Menstrual spotting occurred for two straight weeks until period came on. This was not a normal cycle for me as I never experience this.

miscarriage of the 16-17 week fetus; This is a spontaneous report from a contactable consumer (patient). A 30-year-old female patient received the first dose of BNT162B2 (Pfizer-BioNTech COVID-19 vaccine, lot number : ER8730), via an unspecified route of administration, administered in the left arm on 26Mar2021 at 16:30 as a single dose for COVID-19 immunization. The patient had no medical history and no known allergies. The patient's concomitant medications included unspecified prenatal vitamins. The patient did not have other vaccines in four weeks prior to the COVID vaccine. On an unspecified date in Mar2021, the patient had a miscarriage of the 16-17 week fetus. The patient had surgery to remove the fetus and tissue. The mother was due to deliver on 09Sep2021. The outcome of the event was recovering. The patient had a nasal swab COVID-19 test on 22Apr2021 with a result of negative. The event was reported as life-threatening.

Miscarriage. I was 5 weeks pregnant at the time of the 2nd Pfizer COVID vaccine on 4/23/21. On 4/22/21, the pregnancy was confirmed by Ob/Gyn through a blood test, urine sample, and ultrasound. I was at the time and am a healthy 30 year old woman without pre-existing medical conditions or any conditions that would put me into a high-risk pregnancy category. The estimated due date was 12/20/21. Received 2nd COVID on 4/23/21. At 3:30pm on 4/28/21, I began miscarrying the pregnancy. On the same day at 4pm, I was at Ob/Gyn and they confirmed that the pregnancy was likely miscarrying through an ultrasound and blood tests. IMPORTANT: On 4/28/21, the pregnancy measured exactly the same in size as it did on 4/22/21. In other words, the pregnancy either STOPPED growing the SAME DAY it was confirmed or the EXTACT NEXT DAY, which was the day I received the 2ND COVID VACCINE. I discussed with my Doctor wither to proceed with the 2nd Covid vaccine and it was suggested that while it hasn?t been tested extensively in pregnancy, it was thought to be safe.

My period came early, which it has never done before. It came on April 20th when it wasn't supposed to come until the 27th. It started out as spotting, then became heavier. It has since become lighter in flow but I am still bleeding as of 03May2021. Color is inconsistent compared to other cycles. It ranges from bright red to rust color red.

After both shots I got my period exactly 3 days later. I never really get my period because I am on the nexplannon implant for birth control. I also had all the period symptoms. Sore breasts, acne, and very bad cramps. Worse than normal.

Patient received the first dose 3/26/21 and believes she conceived 3/10/21. She began spotting on 4/5/21 and the bleeding continued getting heavier until 4/19/21. The OB confirmed miscarriage on 4/28/21.

12 weeks pregnant at time of shot. Due Nov 11 2021. Second pregnancy. First pregnancy had no abonormal instances. Vaginal bleeding started at about 5pm. Lower abdominal pains + constipation before bleeding. Went to ER that evening and got RhoGAM. 300 mcg. Intramuscular.

After the vaccine, I began to have fever and body ache for a couple of days. The next week, 04/20/2021 I began to have abdominal pain and blood in my urine. I went to the doctor. The diagnosis was that I was having a miscarriage. I was supposed to have 7 weeks of pregnancy. The embryo appeared to have about 5 weeks. It appears that after the vaccine the embryo stop developing. On 04/21/2021 the miscarriage took place without any medication taken to accelerate the process. Before my schedule second dose for the vaccine, I called the clinic and asked for a doctor appt. I wanted to talk to a doctor regarding my early pregnancy stage and the upcoming vaccine. At first I was denied. Then after a struggle I was provided with a lab test to confirm my pregnancy. On 04/12/2021 in the morning, I called the clinic to speak with a doctor and ask his/her opinion about the vaccine and my early pregnancy. After an struggle, the receptionist told me that the nurse who had the results of my pregnancy was busy. She would call me later on the date. That been pregnant or not, the vaccine was secure. I asked that I wanted to have a talk so I can make my decision. But the receptionist repeated the same. And after I said thank you but the phone was cut. That is when I decided not to miss my vaccine appt.

Pain in both arms in area of injection site. Nausea and fatigue. Went to er for extreme pelvic pain and admitted to hospital for appendicitis. On antibiotics now

Headache, Tylenol, symptoms controlled, symptoms resolved after 24 hours Fever, Tylenol, symptoms controlled, symptoms resolved after 24 hours Chills, rest, symptoms resolved after 24 hours Fatigue, rest, symptoms resolved after 48 hours Nausea, rest, symptoms resolved after 24 hours Early menstruation: Came 24 hours after second shot, 2 weeks early, always have been on time in the past and has never come early before.

So my PMDD came back with a vengeance after the second dose of the vaccine. After the first dose, I had the most painful period t the most painful 12 hours of my entire life, so I was worried about THAT. Turns out I was physically fine, but mentally very unwell. It felt different/ similar to when I was 19 and tried an antidepressant that made me feel actively suicidal, so. I don't know how to describe the difference in feeling, but it came out of nowhere, was very strong, I wanted to kill myself for half of April, and it wasn't for any *reason* whatsoever, it was just hormonal. So my best guess is that the second dose interfered with the balance my birth control gives me now, and the shock to my system made it even worse than it had been in the past. This lasted from the 4th, through my period, and after, until the 19th. I was barely able to take care of myself at all during this time, and it was very difficult/ debilitating. Also scary!

I'm a healthy athletic 30 year old female and I've always had regular, on-time periods. My period was due June 7th and my second vaccine shot was May 25th. I am now almost two weeks late and not pregnant. I've been having premenstrual symptoms now for the entire two weeks including sore, swollen breasts, cramping, and bloating. It's like my body is expecting my period to start any day now but it's not. Two days ago while I was brushing my teeth and getting ready for work, I suddenly got the worst sharp pains in my pelvic region and rectum to the point that I couldn't stand. I had to lay down for an hour. I've never felt anything like that before. I'm a very healthy & stress free individual that does not take any medication (birth control, over the counter meds, etc.) The Pfizer vaccine is the only "new" thing to come into my body.

My Pfizer shots were delivered on Feb 18 and March 12, 2021. I experienced irregular menstrual symptoms from March 1-March 13 of 2021.

On March 1 almost 2 weeks before my expected period, I started spotting and cramping. The light bleeding continued for 2 weeks, at which time it transitioned into my typical period with regular cramps and bleeding, in line with my usual experience. My GYN did not know what could be causing this (I later found out there have been many irregular menstrual symptoms associated with Covid-19 vaccines. I don't regret getting it, this was fairly mild, but if there is a causitive link between the vaccines and mesntrual side effects, women NEED to know this. Menstrual and female reproductive health side effects need to be observed and measured in clinical trials, and female patients need to be advised what to expect.

After the first dose on February 16, my period started one week after the dose which was about 14 days early. I am super regular and now after both doses I have started my period early so I am concerned it?s related to the vaccine.

I had a slight period the day after (03/05/21) which lasted about 3 days. I thought it was just a coincidence and didn't think much of it. The same issue happened after I got the second dose on 03/26/21; I got my period again. My period is usually normal (every 27-31 days), so it was definitely strange to me that my period came so soon and both times were immediately the day after the shot. It was just a normal period with no blood clots or anything abnormal, but I do feel like it's an adverse reaction of my body to the vaccine.

Extremely heavy menstrual cycle - double the duration, much heavier flow, much stronger typical ?pms? - including cramps, headache, and fatigue. Easily my ?worst? menstrual cycle since I began menstruating.

About one week after getting the Covid vaccine I started to experience menstrual spotting. I have never experienced spotting in my life prior to getting the vaccine. I track my cycle on an app and this spotting occurred 2-3 week before I am expected to get my period. This was a very noticeable side effect and something I?ve never experienced outside of getting the vaccine.

I have had my period 3 times in 2 weeks and extremely heavy. Really bad cramps and hormone swings. I have broken out all over my face due to the hormone changes. This is something that never happens. I did have a headache and extreme fatigue as well, but the intense hormones and constant heavy bleeding are the worst.

My leg muscles, in my thigh specifically, are very sore all the time. Occasionally, the muscles on the back of my leg are sore as well to the point that it hurts to sit down and I have to ?catch myself? with my hands to avoid using my leg muscles to sit. This is unresolved. Additionally, my menstrual cycle immediately following my second shot was late by 3 days (I?m always on time). This was resolved by my next cycle.

I started my period early (13 days since the start of my last period). I know it could be stress but 13 days is too short of a cycle. I'm not sure yet if it was heavy spotting for the one day or if it's going to keep going. It seemed like day one of my cycle last night but it's light again this morning.

The patient's physician (OBGYN) had advised the patient to report side effect/adverse event to the vaccination site/VAERS. Date of event had occurred exactly one week to the day of vaccination (first dose of vaccine). Abnormal bleeding/spotting in-between periods is extremely unusual and abnormal for the patient. Patient is not pregnant or breastfeeding. No patient use of medications/prescriptions/antibiotics/birth control/hormonal therapy/surgeries/injuries/drugs/alcohol.

I was 7 and half weeks pregnant when I received the second covid vaccine, then a week later, I began to have vaginal bleeding. 5 days after bleeding began, I miscarried while at home, passing a lot of tissue and lost a lot of blood, had to go the ER, had a syncopal episode due to blood loss and had to have an emergency D & C.

I started with chills/fever the night of my 2nd shot. All night, I had body aches, joint pain, migraine, unable to sleep and SEVERE stiff neck pain. The most concerning side affect for me was I felt as though my central nervous system was affected. I had difficulty speaking, formulating sentences and experienced general confusion. I couldn't communicate with my husband to tell him how sick I felt or what I even needed. The fever went away after 24 hours, the joint pain stuck around for 3-4 days, as did the migraine and exhaustion. My menstrua cycle has also been affected. It's heavier, lasting longer and affected my usual cycle time.

I would like to note that I have always had a very regular monthly menstrual cycle where my period was no greater than 7 days. I started my period the day I got the Pfizer COVID19 vaccine. I noticed my period lasted for a total of 12 days instead of the usual 7 days. My menstrual period was also lighter than usual.

Joint pain and fatigue started the evening I received the vaccine. Fever and headache woke me up out of my sleep around 3:30am that night/next morning. All symptoms continued throughout the day after receiving vaccine. Two days after receiving vaccine, my menstrual cycle started earlier than it should have, cramps were more intense than usual, bleeding was much heavier than usual, and clotting in cycle was noticed, which is also abnormal for my cycles.

Heavy period leading to Iron Deficiency Anemia; First period starting 1 day before vaccine and heavy bleeding started 1 day following vaccine. Bleeding last 14 days. Second period started April 16 and lasted 15+ days Weight loss of approximately 20lbs in the following 6 weeks

I was on the second day of my menstrual cycle and experienced very severe abdominal pain/cramping for several hours. Flow remained normal, maybe even slightly lighter.

I got my period the very next day which was 3 weeks early from a period that is always regular for me. It was also different and not an atypical menstruation.

At the exact moment of injection , complete arm tense. After standing immediately on 1st injection I experienced dizziness. During my ?observation? 15 minutes I was walking around the store with blurry and spotty vision. I almost felt like I was going to fall over, and had the feeling immediately that I needed to go to sleep. After eating ( this was at 9 in the morning after a full night of good sleep) I felt as if I needed to go to sleep immediately. I continued to sleep for two hours after the first dose. My menstrual cycle was delayed this month as well by 7 days and very heavy. The second dose was very similar. I have to say the pharmacy was excellent as I told them my experience with the first dose. I sat for 15 mins to make sure I wasn?t going to fall. I sat but still felt dizzy and saw spots with blurry vision. Same reaction. I went to sleep without hesitation like there was not a force in the world that could stop me. I have continued on both occasions to feel the effects around 24-48 hours after.

Prior to second vaccination last menstrual period was regular and lasted 22jan21-28jan21. Post vaccination I started to have spotting 2feb21 which gradually became full menstrual bleeding through 6feb21. I started menstrual bleeding again on 14Feb21-24Feb21 then had a few days of no blood, started menstrual bleeding again 28feb21-3mar21. I experienced more regular menstrual bleeding in the last month 1apr21-8apr21 and have not gotten my period this month yet.

Menstrual symptoms drastically worsened. 3 weeks after my second shot, I started experiencing extremely increased cramping, intensified pain with every day, a much heavier menstruation, and extreme fatigue which normally does not accompany my menses. Treatment is ibuprofen but it does not help the pain at all.

After 8 hours past I then took 3 tablets of 200 mg ibuprofen which still had no response to pain. -The following day my sense of smell was off and still is. It's like a rancid smell? I gave it some time to see if it would go away but it is still present. -I am also experiencing irregularities in my menstrual cycle such as heavy bleeding and very large clots (2-3 in in size). It has made me unable to go about my daily activities and I've been extremely fatigued. I've never had this issue previously and am not on any kind of medications or birth control.

Menstruation began the day prior to vaccination as usual and on schedule. Menstruation ended hours after receiving the second covid vaccine. Typically my menstruation will last approximately 3-4 days. After last vaccine my period has returned on schedule but unusually heavy and lasting two days, the days following I am experiencing spotting which is unusual for me. I spoke to my gynecologist about it and he said this has been reported as a symptom of the vaccine. He asked me to return to his office if my periods are not back to normal within 3-6 months.

I was 22 weeks pregnant when I received the first dose of the Pfizer vaccine. Then, 2 weeks later when I was 24 weeks pregnant, I started having vaginal bleeding. I was in the hospital for 3 days as the doctors believed I may be going into very early labor. They suspect a partial placenta abruption. As a result, my cervix was found to be short, also indicating potential early labor coming. I was put on bed rest. Two weeks after the bleeding started, I lost much of my mucus plug (at 26 weeks). When at hospital at 24 weeks, I was given steroids to make my baby?s lungs develop faster just in case he?s born soon. I was also prescribed progesterone which I?ve been taking nightly. I?m now also taking magnesium supplements and drinking chamomile tea. This may be unrelated, but I have also been found to be low in iron so now I?m taking iron supplements too. Due date is Aug 2, 2021; I?m 31 years old; I am currently 29 weeks pregnant and still have not gone into labor; This is my second pregnancy, my first pregnancy was two years prior, and it was 100% healthy.

Menstrual bleeding since second vaccine till date. Its been more than a month now. Bleeding doesnt stop. And its heavy.

Went in for my depo shot the first week of March and I had my first covid shot March 26th 2021, the second shot on April 16th 2021. About two days later I started to bleed, which is normal with the depo shot, but after the usual amount of bleeding time I thought this isn't right (usually a week). I bled for over a month (6 to 7 weeks) and firmly believe it is due to the covid vaccine.

Did not know we were pregnant, received vaccine. Got positive pregnancy test a few days later and miscarried the next month at 8 weeks with baby measuring 6 weeks. Have no history of miscarriage and two full term healthy babies prior to this. Unknown if related for sure, but this is the only change and timing seems important to report as possibly correlated.

I have been bleeding heavily for 11 days now.; This is a spontaneous report from a contactable consumer. A 31-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 2 via an unspecified route of administration, administered in left arm on 26Apr2021 02:15 (Batch/Lot Number: EW0164) as 2nd dose, single for covid-19 immunisation.

The patient underwent lab tests and procedures which included sars-cov-2 test: negative. Outcome was not recovered. No treatment received. Doctor or other healthcare professional office/clinic visit required.

I have yet to get my period and I?ve always been on time since it began. Other women have also told me they experienced pain or no period after as well

Amenorrhea. After vaccine I missed 3 periods (withdrawal bleeds, since I take OCPs). Periods resumed in June 2021.

Early menstrual cycle. Prolonged spotting prior to and after menstrual cycle. Duration has been 3 menstrual cycle. Issue has not stopped.

The day I received my first COVID vaccine (May 5th) I started bleeding irregularly as if I was spotting or beginning my menstruation cycle. However, the blood was VERY dark, like maroon in color. The bleeding continued until May 24th. My previous period in April was a regular period that had begun on April 23rd and lasted for 6 days. My irregular bleeding during the entire month of May was accompanied by infrequent cramping and breast tenderness.

This patient wanted to report that she began her period as expected on 5/11 but has had spotting to normal menstrual bleeding for 30 days since onset so far. She is wondering if it could be related to the vaccine

1. The following day I had a fever of 101, chills, headache and nausea which lasted for about 10 hours 2. Severe exhaustion for 4 or 5 days 3. Missed menstrual cycle (delayed menstrual cycle by 3 weeks) 4. Consistent diarrhea for the next month

The breast on the side that I got my vaccine in was particularly more visually swollen and tender/sore than the other breast for a full week prior to the period that happened after. This is unusual for me. That breast is ever so slightly naturally bigger than my right, but they always are affected equally/in tandem in regards to my cycle.

At the beginning of January, my husband and I had already been trying to conceive. I received my second dose vaccine on 01-07-2021. In the first week of February I found out I was pregnant. By the end of February I had a miscarriage. I had the miscarriage on 02-24-2021. The day I miscarried I was going to have my first gynecological appointment to check my baby. I do not know if the vaccine had anything to do with my miscarriage. I was hesitant to getting my second dose but I still went through with it. I just think it is important for mothers who are expecting to wait at least till their second trimester to receive the Covid 19 vaccine, my opinion.

The day after vaccine I started experience period symptoms like cramps and bleeding. I'm still bleeding as of today 6/16/2021. I am on birth control and am not supposed to be bleeding yet.

Menstrual cycle was 2 weeks late. My period was much heavier when it did come. And cramping was more than I ever experienced. I experienced my second period since my first vaccine 28 days after my last period. I did not have the cramping like the previous cycle, but i still experienced heavier than normal period. Separately, my memory recall seems to be worse post-vaccine.

Beginning the month after the first injection, my menstrual cycle became extremely heavy, with a large volume of very big clots. I have never experienced this in 20 years of having a period. My cycle went from 4 days to 7, and I have to wear an adult diaper during these days now. I have had bloodwork and an ultrasound, which showed increased thickness in uterine lining. Now having to have a biopsy done. This has continued with every cycle following my first injection.

Missed period over the past 5 months. Last period was from 1/8/21-1/14/21. I received the first dose of the vaccine following my last period. I have not had a period since and I?m not on birth control not pregnant.

I found out I was pregnant on March 3rd, 2021 from an at-home pregnancy test. The pregnancy was confirmed with blood work on March 6th, 2021. I received my first dose of the covid vaccine on March 8th, 2021. I noticed some light spotting afterwards. The heartbeat was confirmed on March 22nd and I was told I was six weeks along. I received my second dose on March 29th. The heartbeat was confirmed again during another ultrasound on April 20th, 2021. During an ultrasound on May 4th, 2021 I was told that there was no longer a heartbeat and the baby had stopped developing a week prior. This missed miscarriage resulted in an D&C on May 11th, 2021.

Awoken throughout the night with extreme body aches (Eye sockets, neck, hip sockets--worst )and migraine. Around 5:30am I took two extra strength Tylenol to no avail. I proceeded with chills, shakes, fever, cold hands and feet, sweating, exhaustion, and loss of appetite. These expected symptoms subsided/ were manageable at approximately 5:30 pm. At 7pm, I began having trouble climbing the stairs and had intense pain in the center of my chest. I could breath alright (I was NOT light headed), but couldn't alleviate the chest pain. I went to sleep at 8:30pm in hopes that it would dissipate. **(Did not go to hospital because we are military, my husband is TDY and I had no one to watch our children. This is not to downgrade the fear or intensity of the pain. I have a very high pain threshold- this was awful.)** Saturday (Day 3 after vaccine) no chest pain, but began spotting (my period is very regular and tracked diligently-I'm not meant to start for another 8 days), still had a very sore neck/ migraine, and swollen/painful lymph nodes in my armpit ( on the vaccine side). Sunday (day 3 after vaccine) still spotting heavily, painful lymph nodes, and migraine.

Prior to the vaccine I had normal periods. After the second dose of covid vaccine I didn?t have a period. For a month and then when it started it lasted for 34 days. My gynecologist said there was nothing functionally wrong. They did ultrasound and bloodwork and everything was fine. Said it could likely be an adverse reaction to the vaccine based on the timing

At the time of my first vaccine injection on 3/14/21 I was approximately 6 weeks pregnant. I suffered a missed miscarriage somewhere between then and 4/9/21, my first prenatal checkup and ultrasound.

Hives started on my elbows for about 10-14 days, then spread to my knees, and feet, then spread all over my body. Originally thought it was a medication reaction and switched oral contraceptives, but hives persisted. Stopped taking all medications and supplements except for lamotrogine and antihistamines. Contacted my immunologist on March 5, 2021, "I am now weaning off of my lamotrigine so I can clear everything out of my system. In the last couple weeks I have Taken prednisone 40mg x2 days, 30mg x2days, 20mg x 2days, 10mg x 2days. Then did a medrol dose pack. And have taken hydroxazine, and Zyrtec. The oral steroids just toned it down a little. The day after I finished the medral I woke up the the worst they have ever been. The only place they weren?t was my face. I?ve been applying hydrocortisone 2.5% 2 weeks on 1 week off and it seems to help it mostly calm down during the day. At night everything flares up and in the morning I wake up to find them back. Some days better than others. I also got blood work done and everything was within normal ranges. My last allergy shot was in December." Started on 2 zyrtec and famotadine twice daily, along with hydroxazine, benadryl, or doxepin PRN. This helped for about a week, but the hives worsened after that week. Spoke with immunologist again. Started on Xolair injections. Following the second Xolair injections the hives decreased significantly. Taking the Xolair injections monthly and taking zyrtec in the morning and famotidine before bed keeps the hives mostly at bay with few appearing every few days, but not all over like they were. (I have picture documentation for all.) I have since started back on all supplements and medications with no adverse reactions that were not previously stated. Other adverse reactions are: abnormal menstrual cycles starting in January (I have been extremely regular with the same week since the start of menstruation at age 11, even after pregnancy), severe brain fog and difficulty remembering, new onset gut issues, edema and angioedema with the hives.

I had two regular menstrual cycles following my vaccine, and my current cycle has thus far lasted 21 days with no signs of stopping. It is heavy enough that I need to use four tampons a day.

Menstral cycle has been every 4th Wednesday my whole life and after the covid vaccine it has fluctuated tremendously.

Excessively heavy menstrual bleeding which began 3 days after the 2nd dose of the vaccine. Heavy bleeding continued for two days. Two days after heavy bleeding ended, symptoms of fatigue/headache/anxiety began.

So basically at the seventh of July 2021, I had a pinkish red discharge. Then after the bleeding stopped there was some brownish discharge and I went to the doctor, the doctor monitored me on July 8th, 2021, checking baby's heart and movement. They also checked my vagina and cervix to confirm there was no more bleeding at that time. They said I was okay and they not concerned about it. They also did a test of my urine and found nothing abnormal. I was at the doctor approximately three hours. This is my first child so I have not had any others. My date of delivery is September 21, 2021. The doctor I saw was a certified NP.

Ok so well on May 15 I had a confirmed pregnancy test however on May 27, 2021 I had sharp pains in my stomach. I passed blood clots. I went to the ER and they confirmed there was no fetus, and they did testing. It came back that I had passed the embryo. They performed some blood work, which included a test for antibodies and that came back elevated so therefore I was told to have Hashimoto's Disease. Prior to the vaccine I was not diagnosed, so this is the information that I have. The time of miscarriage, I would have been 5 weeks pregnant so it was considered an early pregnancy loss. So I have had one pregnancy three years ago and since then, I have been trying to get pregnant and through IVF. My estimated date of delivery would have been January 27, 2022.

Extremely early menstrual cycle. My period ended 2/23 one week before I was vaccinated and started again 2 days after vaccination. My periods are regular (between 27-29 days) so this is very irregular and concerning. No other changes has occurred in my life to cause such a drastic cycle change. I am only on day 2 of my period but so far it looks like any other day two so I'm assuming it will run the full 5 day course.

Nausea on public transportation while returning home on 3/15. Fever of 99.4-99.8 on 3/16 only. Headache, body ache, elevated period cramps 3/15-3/17. Sense of smell was improved.

Early Menstruation. I started my period two weeks early and am having a full blown period. It is heavier and longer in duration. Normally my period is for 4 days. I am on day 6 now.

Period came early - my last period finished up 2 weeks before my shot (April 1) and my period started up again on April 11 which is much earlier than usual.

Started my period 2 weeks early almost immediately after receiving the 1st dose of vaccine, despite taking hormonal birth control daily that is supposed to regulate my monthly period.

Heavy and very long menstruation! My period started fairly on time 6 days after my shot, and still going heavily (today is day 8, my periods are normally 5 days and very predictable). I am not on any birth control and had my most recent gyno check up three weeks ago and everything looked good!

Interruption in menstrual cycle. I have not had a period since first or second dose of Pfizer vaccine and pregnancy is not a possibility. Vaccine appears to stop effects of sertraline for about a week. I experienced manic depression for about a week both after first and second dose of vaccine, despite not having any issues while on sertraline prior to being vaccinated. It was like my sertraline medication completely stopped working.

Was unknowingly pregnant at the time of first and second shot. Found out I was pregnant and miscarrying the day of the second shot (4/6/21). Don?t know if the vaccine caused the miscarriage but I thought i should report it. Started bleeding within hours of the second shot and blood tests on 4/15 and 4/17 showed I was losing the pregnancy.

I read that anecdotal evidence has appeared on social media about the vaccine affecting women?s menstruation cycles . After the second dose, my period was one day early and on the second month it was three days late.

I previously reported swollen lymph nodes in my left arm but since the , April 9 I began spotting for 3.5/4 days. The discharge was pink/red and jelly like. Was not free flowing or strong enough to fill a pad. I took two pregnancy tests and both were negative. Menstrual cycle: 03/28/21-04/01/21 Vaccine dose 2: 04/03/21 Spotting/bleeding: 04/09/21-04/12/21 Negative pregnancy tests: 04/12/21 & 04/15/21 *Predicted period: 04/26/21

A half hour after receiving the shot I noticed a taste of iron in my mouth. The evening after my second dose I got my period, I was not due to have my period for another two weeks. My period was very heavy flow, extremely painful cramps. Four days after my period started I experienced heavy and severe nose bleeds. The nose bleeds felt concerning - they would start randomly and flow heavy, taking 5min to stop. I felt very fatigued.

I am 3 months post partum. The day after I received my shot, my pelvic area had a odd feeling. Almost like my uterus felt a dull very very mild pressure. Day 2 after receiving my shot, I started to bleed. I am exclusively breastfeeding and I have never had a period start this early with all of my other children. Normal is 7 plus months for me. This period was also not a normal period. I had zero cramps. I felt nothing. I never have had a period with zero cramps. Lasted for 7 days.

My menstrual period was due a day or two after the vaccine but didn?t arrive until cycle day 40. Then I got a period two weeks later (I?ve never had a two week cycle) and then two weeks after that - unless it was a cycle with bleeding in the middle of it for a few days. Then the next period I had was incredibly heavy with lots of clots and very painful for about 4 days. I?ve never experienced that.

Patch of skin on right forearm became very dry, red, and a inflamed for several days post-injection. My period also came approximately 7 days early and was unusually heavy (leaking through a super tampon in only 2-3 hours). It lasted for 2 days, as opposed to my usual 4 days.

Intense cramps in the middle of night and the irregular start of my period just hours after taking the shot. Intense period cramps and heavy bleeding.

Sore arm and fatigue that first evening. I had those for about 24 hours. Miscarriage - I had my first doctor's appt on 4/14/2021 and I found out that there was no embryo - Anembryonic pregnancy (blighted ovum)- my body thought it was pregnant but there was no embryo. I had to take medication to induce the miscarriage - I took that last week on the 20th. I've passed all the tissue but I have to wait for it stop cramping now.

I received my first dose of COVID-19 (Pfizer) vaccine on 3/25/21, second dose was received on 4/15/21. My menstrual cycle was supposed to start on 04/10/21, as of 4/25/21 I am 15 days late. My menstrual cycles are normal and predictable, with cycles lasting 25-26 days, and pre-menstrual symptoms starting about 5 days prior to initial bleed. I have never had a missed or have had a late menstrual cycle with the exception of pregnancy. All pregnancy tests have come back negative. Since receiving the COVID-19 vaccine, there have been no changes in my lifestyle, diet, or mental health which would lead me to believe caused this late/missed menstrual cycle. As of 4/25/21 still no sign of my menstrual cycle or pre-menstrual symptoms.

I was 9 weeks postpartum at the time of my first vaccination, exclusively breastfeeding and told by my OBGYN not to expect a menstrual cycle for quite a while, maybe a year or more depending on how long breastfeeding continued. Two days after my vaccine I started my period and have had second one since then.

I was supposed to start my period around March 25, 2021 and I did not get it. I have since gotten my second vaccine, and it has been 5 weeks since my first. I am on my 73rd day of my cycle, and still no period. I have been experiencing fatigue, lots of discomfort around my ability to regulate my temperature, and general discomfort and aches.

Menstruation came a week early and was significantly more painful than usual. I am nauseous, shaking, pale, and the cramps are bad enough that I had to leave work. While I usually have a painful period, it's regular and the discomfort is controllable with ibuprofen.

I had no period for 50 days and I have been regular every month for the past 2 years. I am not on birth control.

My period is very light, barely spotting. This never happens to me and there is zero chance I am pregnant.

Extremely heavy and long lasting period even during active birth control pill days and extreme cramping and spotting in-between period days. Period coming every other week instead of every 28 days.

excess uterine clotting; enlarged lymph nodes in the auxiliary of left arm.; two uterine cycles every moth; This is a spontaneous report from a contactable nurse (patient). A 32-year-old female patient received the first dose of (Solution for injection), via an unspecified route of administration, administered in Arm Left on 14Jan2021 10:00 (received at the age of 32-years-old) as SINGLE DOSE for covid-19 immunization. The vaccine was administered at a hospital. The patient did not receive any other vaccine in four weeks prior to receiving. Medical history included covid-19 from Nov2020 to an unknown date. The patient was not pregnant and had no known allergies. Concomitant medication included vitamin c [ascorbic acid] (VITAMIN C [ASCORBIC ACID]) and multivitamin. Within 48 hours, on 15Jan2021 10:00 AM, the patient had enlarged lymph nodes in the auxiliary of left arm. 16 days after the vaccine, on 30Jan2021, she started having excess uterine clotting and have been having two uterine cycles every month since the vaccine (Jan2021). She stated that she had COVID-19 in Nov2020 and her cycles were normal. She has been checked with her doctor and refereed to a GYN for further testing. The patient underwent lab tests and procedures which included sars-cov-2 test: negative on Apr2021. The adverse events resulted in doctor or other healthcare professional office/clinic visit. It was unknown if patient received therapeutic measures in response to the adverse events. Outcome of the events was not recovered.

My menstrual cycle started a day before my shot was administered. I track my cycle with an app, and it usually lasts 3-4 days for the past couple years, at least. It?s also quite regular. The cycle I started the day before I got my shot lasted an extra three days at least, and was slightly heavier flow for longer than usual. I count that as my first effect that was not a ?normal? symptom. Yesterday, 5/11/21, I started ?spotting? again, or having trace amounts of blood when I urinated. I?ve felt bloated as well the last couple days, as I do when I?m starting my cycle. Today my cycle has gone from ?spotting? to ?light? flow, with more noticeable cramps; in other words my cycle seems to be starting again, two weeks ahead of schedule. My next shot is scheduled for this upcoming Monday, 5/17/21. My next menstrual cycle was supposed to start around 5/25/21. My cycle is usually consistent within a day or two of its estimated schedule.

The batch/lot number for the vaccine, bnt162b2, was not provided and will be requested during follow up.

My period was extremely heavy for a few hours on day two of my cycle. I couldn?t leave the bathroom, the blood was very thin and had lots of clots. It was just evacuating my body so quickly. Normally, my period is very consistently light. This has never happened to me in my entire 20 years of menstruating. It was painless, no cramps, just very heavy and then after a few hours of nonstop bleeding, it went back to normal. It?s almost like the entire living decided to shed in a few hours rather than the extended few days that it normally happens in. The whole cycle still only lasted a few days like normal, just those few hours were noticeably abnormally heavy.

Had irregular menstrual cycles following the vaccine. I?ve always had regular periods that come every single month 1-2 days early but after getting vaccinated I?ve had 2 additional periods out of that usual cycle for a total of 3 within one month

Golf ball sized lump under left armpit (lymph nodes), appeared within 24 hours of vaccine. No treatment. Swelling slowly decreasing. Lack of menstrual cycle.

patient began having irregular and heavy menstrual bleeding for approximately 30 days following vaccination. Also broke out into a rash consistent with pityriasis rosea.

The day following my vaccination (4/24/21) I awoke feeling completely nauseous and dizzy. Upon getting out of bed I immediately sat on the floor due to the extreme dizziness and fear of passing out I felt. After a few minutes in this state I vomited. I had a fever which I managed with Tylenol. I felt fatigued and weak the entire day. I ran a fever the entire day, again managing it with Tylenol. The following day (4/25/2021) my fever was gone and I felt better, however about midday I began experiencing cramps and vaginal bleeding. I was 5.5weeks pregnant with an estimated due date of 12/24/2021. I went to the ER with concerns of a miscarriage. Based on abdominal ultrasound and subsequent HCGquant testing over the next week it was determined I had encountered a miscarriage and lost the baby.

The day after the second dose I had extreme fatigue and muscle aches. I felt better after two days and I just had some soreness in my arm. I am pregnant with twins and I experienced vaginal bleeding on 05/07/2021. It was determined that it was due to Placenta Previa. I was 14 weeks pregnant at the time.

The patient reported she had the first dose of the Pfizer COVID 19 vaccine on 28Jan2021 at 16:00PM in the left arm. About 10 minutes into her wait period (28Jan2021), her heart started to pound; her lips numb and face went numb and warm; she had metallic taste in her mouth; and her mouth/tongue and throat felt itchy. She went up to the nurse to tell her about her symptoms and they hooked her up to an O2 monitor that showed her heart rate at 160 beats per minute but her 02 was okay, it was not under 97%.

She did visit her allergist before getting the vaccine and he said none of her allergies were related to any of the ingredients in the shot. Then she saw the allergist again after the shot and the allergist didn't think she needed to be concerned as the allergist said her symptoms are not in line with an anaphylactic reaction. She is planning to receive the second dose of the vaccine on 18Feb2021. Outcome of the event 'stabbing shocks in her chest (chest pain)' was recovered on 30Jan2021. Outcome of 'her period is now 11 days late' was recovered on unspecified date. Outcome of tired was recovered on 29Jan2021, while outcome of the remaining events was recovered on 28Jan2021.

Irregular menstrual cycle: extended/exacerbated pms symptoms, 3+ day delay in period onset, heavier bleeding (incl. larger clots), bleeding has returned 2 days post-late period.

On my 8 week appointment check up; the OB discovered there was no longer a heartbeat they could find for baby. I subsequently went in for a recheck 1 week later ( today) to discover there was still no heartbeat for baby. I was diagnosed as having a misses miscarriage. I was given the same medication that patients receive when they want to have a medical abortion by choice.

The Pfizer vaccine triggered an early period and for the last 2 months my cycle has been very early and significantly heavier bleeding. This is problematic because I am a breast cancer patient and more frequent periods can lead to higher recurrence risk.

Spotting during ovulation for 4 days. I have never had spotting during ovulation before that I know of. I had one abnormally short light period in May 2017 that may have been ovulation bleeding. Otherwise it has never happened until after the covid vaccine. I have had ovulation bleeding every cycle since I have gotten the vaccine. It lasted one day the next cycle and 4 days the cycle after.

As the days continued I began to develop more bumps on Left heel that traveled to my right foot. In total I have 10 plantar warts that developed which has caused my to be temporarily disabled from work. Shortly after when I recieved my menstraul cycle, it was extremely heavy and full of large blood clots. This was not my baseline. we are in the month of June and I have had irregular periods ever since vaccine. In March 2020 I had a cardiovascular incident that resulted in a RIGHT BUNLE BRANCH BLOCK. I'm following a cardiologist. I have had multiple issues with my body ever since I received this vaccine and urge the public to please read and educate yourself before you get it. Im just now starting to experience tingling in my arms and legs. All of the issues Ive list are all AUTOIMMUNE ISSUES. This vaccine has destroyed my health and hijacked my immune system.

Pfizer-BioNTech COVID-19 Vaccine I experienced shat I would describe as very heavy menstrual bleeding the day of receiving my second dose (6/12/2021). The bleeding was comparable to the amount typically experienced a few days after giving birth. It lasted for about a day and a half. A week later, a small amount of bleeding occurred but only lasted for about six hours.

History: live births in 2008 and 2017. Abortion in 2016 using misoprostol. Miscarriage 12/20 at 6-7 wks. Received dose 2 around 4-5 weeks of pregnancy.

I am in the COVID vaccine monitoring program and was called after my latest V-Safe report. I had 1-2 miscarriages this spring and had a D&C in June 2021. The V-Safe called asked me to file a report for CDC tracking. I was not pregnant at the time of my COVID vaccines (Dec 2020, Jan 2021), so unlikely to be related.

Within 3 hours of the first shot I started to feel like I was having burning menstrual cramps in my abdomen along with feeling like I might have diarrhea. I haven't had a period or period symptoms in over six years since I am on birth control. Right after those symptoms, almost 4 hours after, I began to feel like I was high for about 3 to 4 hours that feeling lasted. I was still able to concentrate but felt pretty high. A small symptom from the 2nd vaccine that didn't last long and happened within about 20 hours was the taste of chalk when I ate food. I couldn't taste my breakfast or coffee it just tasted like chalk. That went away by lunch at around noon.

My period became irregular after first dose of vaccine. Skipping March then April was very intense period. No period in May. June was very intense period and July have been regular in timing and intensity. My assumption is the side effect is (if caused by vaccine) has run its course. Didn?t impact my life much. Didn?t need to seek medical attention. Thought it would be good to share though.

Very heavy period. So much so that when changing my pads there was actual weight (feeling of heaviness) because it was so full of blood. Never have I ever completely filled a pad to the very brim/edges of the fabric. This "filled pads" happened repeatedly for several days.

I'm having extreme menstrual side effects. After my second shot in April, by May my period was a little bit heavier and ran longer than normal, but it didn't worry me. I usually only menstruate 4 days and this ended up being 5-6 days and heavier. However, by June my period was about 36 days late from the last cycle and no I'm not pregnant and I wasn't pregnant, but at first I attributed it to stress, however, when it finally did show up on (June 22) I bled for 14 days straight and it was heavier than normal. By July 5, I thought that was the end of my period, but two days later I started bleeding again and this time not only was it was heavier (gushing) but I was passing abnormally large blood clots. I've never experienced anything like this before, and if you look online there are a bunch of women going through the exact same symptoms as me after getting the vaccine. I actually have another close friend who has had issues with her period right after getting the vaccine. So, I went to see my primary doctor on July 23rd and she put me on birth control to help with the bleeding, to get my hormones and cycle back on track. As of now, I'm still bleeding, but it's lighter. I do still pass clots every now and then, but it's not as bad as it was when I wasn't on birth control meds. I just want to report this to you (the CDC) because this needs to be researched. Other women shouldn't have to be worried or surprised by these side effects. As well, we women need to know what are the lasting side effects of the vaccines? Is this excessive bleeding and clotting a short term thing? Is this going to make us infertile? Will our menstrual cycles regular in a few months? We just need answers. It's really scary when it's happening to you and no one (the CDC, health professionals, the media) aren't talking about it openly.

Within minutes of receiving the vaccine Pt said she developed a "fruity" taste in her mouth. She said she got dizzy, extremely hot and felt like she was "swaying" She said she also got what she described as "menstrual like cramps" that radiated all around her abdomen and back. She was under observation as advised per Pfizer protocol. An associate of the Pt noticed she passed out for a second she then turned beet red from her head to her neck as we could see. The associate yelled for us to grab a BENADRYL. They hooked her up to a BP machine and she did present with a spike in BP. After a few minutes, the redness and symptoms subsided. She was observed by the medical staff at the facility.

I had my first prenatal visit on 2/10/21 at which time US showed twin gestation but neither fetus had a heartbeat.

I was 6 weeks pregnant when I got my first dose of the vaccine. I spoke with my OBGYN prior to the vaccine and she said it was safe t get. The day after the vaccine (2/4) I started having some vaginal bleeding, confirmed with ultrasound. This progressed to having a miscarriage, confirmed via ultrasound 2/9. My OBGYN said she does not think they are related, but there is no way to tell. Until 2/4, I had no issues with my pregnancy.

noticed vaginal bleed (~1mL) appeared 3hours or so after vaccine received. Not pregnant and menstrual cycle not slated to start until 10 days later.

Approx 6 weeks at time of second administration with a due date of sept 28th. Would have been 3 weeks pregnant at time of 1st injection. 3 days after second injection, I began to miscarry. This was confirmed by declining HCG levels. Ultrasound to follow in one week.

Nauseous. 1/22 pregnancy test; positive By Friday evening, symptoms started to dissipate. 1/26 Miscarried; 4 weeks 3 days pregnant 1st pregnancy

I was pregnant when I received my second dose of the Covid-19 Pfizer vaccine. My first Covid 19 vaccine was administered 12/28/2020. I got pregnant on 12/31/2020, received my second dose on 01/18/2021 and miscarried on 2/25/2021. I have had two prior uncomplicated pregnancies, and have never experienced a miscarriage. I gave birth to my two daughters, one at 42 weeks and one at 40 weeks and 5 days. My EDD for the pregnancy that ended in a miscarriage was due 09/23/2021.

I ended my normally scheduled menstrual cycle on 02/06/2021, and exactly 6 days later (02/15/2021) I had severe menstrual bleeding with blood clots that has continued to this day (03/02/2021). I went to urgent care and was prescribed Provera to stop the bleeding to no avail. I then proceeded to go to urgent care again because the bleeding had not stopped. At my second Doctors visit, I had an abdominal and a transvaginal ultrasound done, and both of them came back completely normal. I have now scheduled an upcoming obgyn appointment, but cannot be seen until 03/09/2021.

Beginning the day after my shot, I experienced engorging in my left breast. My breast was swollen, hard, and painful to touch. I?m currently breastfeeding my 7 month old, and I wasn?t able to get much milk out. I haven?t had an issue with engorgement since my baby was first born and my milk came in. Since this was unusual, I think it?s related to the vaccine. The engorging only lasted the day after my shot, and it went away that evening (lasted about 12 hours).

Abnormal menstrual cycle-- spotting in between periods. This has never occurred previously and I have not made any lifestyle changes.

Within 24 hour I began to bleed and ultimately had a complete miscarriage of baby. I was at 6 weeks, with 2 healthy children (3 1/2 and 1 1/2 years old) with no prior pregnancy issues or complications.

I have vaginal bleeding and then it stopped on its own after two weeks and the bleed healed up. Dr visit - no treatment - peri gestational hematoma. My due date is 9/18/2021; my second history - I have one living child.

Adverse event: miscarriage Estimated date of delivery: October 2021 Pregnancy history: two previous pregnancies, carried full term, vaginal deliveries, healthy

Bleeding started really heavy/ Soaking up a bunch of different pads; Really bad pain in stomach as well as right pelvic area; Really bad pain in stomach as well as right pelvic area; Pain in right chest area; bunch of pain; Headache; Diarrhea; Nausea; Pain where I got the shot; This is a spontaneous report from a contactable consumer (patient). A 33-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Lot Number: EN6200) via an unspecified route of administration in the left arm on 28Feb2021 at a single dose for COVID-19 immunization. The patient medical history was not reported. The patient mentioned that the only medication she was taking was birth control. The patient got the COVID-19 vaccine on Sunday and had the normal side effects like headache, diarrhea, nausea and pain where she got the shot. The patient took Excedrin extra strength on Sunday night. Then on Monday night (01Mar2021) when she went to sleep there was pain in her chest, her right chest area there was in a bunch of pain. When the patient woke up on Tuesday morning (02Mar2021), she had bleeding, and that bleeding started really, really heavy. She just came off of her period a week ago. She had a full blown period for an entire week and then on Tuesday the patient started bleeding very, very heavily. She was soaking up a bunch of different pads. She was not sure what it was, she had pain, really bad pain in stomach as well as like pain in her pelvic area, right pelvic area. Patient weight was 135 (units unknown). The outcome of the events was unknown.

I got the usual arm pain at injection site the night after getting the vaccine. 24 hours later, I had really bad diarrhea (possibly connected) but nothing else yet. 2 days after, i woke up with the normal fatigue, slight headache, and nausea from upset stomach. But what I did not expect was that 2nd night I got my period a week early and super heavy (I'm on birth control and haven't had my period, except for some spotting, in years). I spoke to some friends and a few of them suprisingly also reported extra heavy menstrual cycles or feeling like they were PMSing around 48 hours after. I couldn't find much online except for a bunch of random people complaining about the same thing, and no study or source of significance to back it. I'm wondering if this something they even looked out for? There seems to be a pretty strong correlation with certain people around my age just from asking around. And I don't think anyone who I spoke to even realized it could be connected until I mentioned it. It was just shocking and significant to me because I'm on set pills that I didn't miss, with no menstrual cycle issues, and I haven't bled more than spotting in years until this. It lessened the next day, and lessened again today since that symptom started.

Began spotting 2 days after the vaccine, it progressed over two more days and just had first miscarriage at 2AM on 3/22/2021

Significant Menstrual period changes. (Typically VERY normal , regular cycle and no other explanations. Not currently sexually active)

Had intense nausea/food aversion begin within 48 hours of receiving first dose. Lasted for 4 days. The day the nausea went away I began my menstrual cycle a week early which has never happened to me before. I have a very consistent 28 day cycle and have never gotten my period this early.

period & cramps eight days early 7 hours after receiving the vaccine. my period is very punctual & over a week early is extremely unusual/does not happen

Menstruation began approximately one week early, and menstrual cramps are stronger/more painful than usual.

I experienced a miscarriage that started with bleeding on 3/13 and was confirmed by ongoing hcg level tests starting on 3/17. I passed a lot of blood and blood tissue in an intense event on 3/16. I did not know I was pregnant at the time and was estimated to be around 9-10 weeks (due date around October 2021) based on hcg levels. I was also breastfeeding at the time of my vaccine. I was advised to go to the emergency room if certain conditions occurred including extreme pain -- I opted to go to Urgent Care that evening to get checked out and to get a blood hcg test. Urgent care was unable to do the blood test and they recommended I call my provider the next day or go to the Emergency Department if certain symptoms occurred.

With my endometriosis medicine I never get my period, haven't for years. Now since vaccine I have got it twice, 1st time day after my vaccine. Talked to my doctor and the vaccine is only connection to any change. Worried it might affect birth control for others.

Adverse was vaginal bleeding the required an overnight observation stay with montoring. Had Blood count, transvasginal ultra sound done, and CDC.

Period came one week early and then a week after that. Spotting. Missed next period. Not pregnant. Confirmed by doctors

Miscarriage. vaccinated December 19th. no Side effects. noticed a bit of pleuritic chest pain. was not bothersome and resolved with ibuprofen. I was pregnant at the time of first vaccine but did not know. had second vaccine 3 weeks after my first without issue. Went to OBGYn for 10 week appointment and there was no fetal pole. Fetus stopped developing at likely 6-7 weeks. I likely miscarried shortly after my second vaccine. .

I have not had a period due to my Mirena, 2 days after my second injection I received a heavy period.

Menstruation started 5 days early. Very abnormal for my cycle, especially with the taking of birth control pill.

2 very heavy and long menstrual periods that occurred right after vaccination and the month after. Painful cramping for 1-2 months

Experienced insomnia and delayed menstrual cycle. Prior menstrual cycles are consistently 28 days in length. Following the vaccine, my menstrual cycle as still not started (as of 04/16/2021). Pregnancy test has reported negative, and pregnancy is very unlikely due to low/minimal sexual activity.

I normally get begin my menstrual cycle every 29 days. After vaccination my next full cycle was only 22 days.

The day after my first vaccine dose (3/20/2021), my menstrual cycle started and I had large globs. Some looked like large blood clots, while others looks like they might contain tissue almost like what you would expect in the event of a miscarriage. I know for certain I was not having a miscarriage. No treatment. Symptoms subsided until next menstrual cycle on (3/17/2021), when I again experienced the same symptoms. Symptoms the second time were not as prevalent as the first time but still noticeable.

Began menstruating a little over five hours after vaccination. This is NOT PT's normal menstrual cycle which normally starts like clockwork a week from now. Aside from other expected side effects like fatigue, nausea, and body aches, pt is resting and doing well.

reported to ED on 4/3 with miscarriage, abdominal pain, vaginal bleeding. I don't have the info on date of delivery it isn't in the ED providers note.

After I received my first dose I started to experience my first symptom on March 30, 2021. I noticed that I had a small lump on the left side of my rib cage beside my left breast which was about the size of a sausage link. The area wasn't painful, slightly tender to the touch and soft. By 4/3/21 the area has expanded to the upper portion of the scapula and it was no longer located on the side of my rib. It was about the size a pear and it was inflamed and very tender to the touch. I couldn't raise my arm and it was pertruding from my clothing and preventing me from sleeping at night on that side. By 4/5/21 the mass had turned into a different shape and direction and it was no longer just primarily on my scapula.. This current shape favored a boomerang and it started on my lower scapula and wrapped around my arm going directly into the middle of my arm pit.. It was about an 1.5 inches wide, inflamed, painful and wouldn't allow me to fully lift my arm or lay on it.. The mass was hard and didn't move, I visited a prompt care and they couldn't decipher what it was. I began to take tylenol and use cold compress and over a few days the mass began to decrease in size and I was able to increase my range of motion obtaining full extension on 4/17/21. The mass is now smaller than a pencil on 4/22/21 and hardly noticable but it was quite an experience.

Longer than normal menstrual cycle. This period lasted longer than 10 days when I normally bleed for 5 days max. This was the first period to follow my 2nd dose of the covid 19 vaccine. I normally bleed 5 days max and have had regular periods for 20 plus years ( since the age of 10).

My first period since having the 2nd shot was very heavy. I usually bleed very lightly, and I have consistently since having the Mirena IUD inserted 3 years ago. This past period (began 4/21 and still bleeding) started last Wednesday and was very heavy from the start. I bled through 3 normal tampons in the span of an hour; I even bled through onto my clothes. This never happens for me. I was also passing large clots, some of them were around the diameter of a golf ball. I also had stronger cramps than normal, and when I would cramp I would feel nauseous, which is also different.

Extreme menstrual cycle change - very, very heavy bleeding with large clots and period lasting much longer in general. Painful cramping in stomach. Severe fatigue - worst I have ever experienced. Still ongoing, day 6 of abnormal symptoms. The last two days I have woken up with a bad headache. I track my menstrual cycles very meticulously and know that this is extremely out of the ordinary.

Started my menstrual cycle 2 weeks early. Have now been bleeding for 20 days. I usually do not bleed because of my nexplanon implant.

I got my first COVID shot when I was 5 weeks pregnant. Due date 12/14/21.

Very heavy menstrual flow during the first cycle after vaccine, noticed small clots. This is a first time ever for me. Also, longer menses than usual by a few days.

Very early menstrual cycle (about 10 days earlier than normal). Stronger cramps, heavy flow. Cramps, pain, discomfort.

I experienced abnormal menstruation for the entire month of April. I had a period (heavy flow) for approximately 3.5 weeks out of 4 that month, with only a few days without bleeding in between. I have had late or absent periods before, but never multiple periods in a month.

10 days after first dose (4/13/21) my menstrual cycle began and at the same time multiple lymph nodes swelled up all over my body. Right and left armpits had multiple (6+ each side) protruding lymph nodes, one node on the right side was very large. Lymph nodes in chest, jaw and groin were also swollen. The lymph node swelling lasted the entire menstrual cycle (about 6 days) and then went back to normal. I drank 100 oz of water on day the node swelling reduced which I account for the reduced swelling but note it also recovered at the end of menstrual cycle.

I pregnant when receiving the first dose of the Covid vaccine. Est due date of November 12th. This was my first pregnancy. Early April (1-2 weeks later) I started experiencing some bleeding and has a miscarriage within a week from the first symptoms.

I received the first dose of the Pfizer vaccine (after having covid in October). I ended up going to urgent care after, as I immediately developed: a sudden cold rush sensation in my chest, a spinning room, a puffy/ numb face and a slowing of speech and confusion/ forgetfulness of basic facts (my address etc). The doctor said that my vitals were fine (no anaphylactic shock) . One day later, my face muscles are feeling a bit sluggish (moreso on my left side) along with what felt puffy in my face from my cheeks to my chin (although didn?t look puffy). 3 days after the vaccine I called 911, Because I was getting numbness and heaviness on the left side of my face as well as in my left arm. Alongside this sensation, I started to feel what seemed to be me period cramps, even though I just finished my period. Paramedics came and checked my vitals, which were fine. 4 days after the shot I was getting heavy gobs of vaginal pale yellow discharge.

The next day after I received the Pfizer vaccine I started feeling sick and lightheaded it had a headache. I think nothing of it and then my menstrual cycle started early and it started off being heavier than usual. Then I notice when I went to wipe myself or use the bathroom blood clots was falling out. Being that I work in the medical field I know like if is not bigger than 1/4 there's nothing to really worry about. So as the day went on and the following days I noticed that the blood clots kept on getting bigger and bigger and coming faster and faster. At this point I started getting concerned, that's when I decided to go to the hospital. At the emergency room at Hospital they really didn't do nothing for me but gave me an ultrasound and gave me some birth control told me to follow up with my OBGYN. But I already made an appointment with OBGYN cuz I just feel like if something was going on and I can't get in to see them till June 30th. They did give me some birth control and tell me your help with the bleeding and for me to take some ferrous sulfate. They said they'd never heard of this reaction before. So I went on May 1st to get my second vaccine. Before I received it, I talked to doctor there and they told me it would be fine for me to get it. Now my symptoms and reactions are starting all over. I'm so concerned about what's going on with my body. I just need somebody to explain to me what's going on. I cannot afford another hospital ER bill again.

Changes in my period. I'm very regular. My period arrives promptly every single month. I'm not pregnant as i tested already. I also have more frequent headaches, pain in my knees and muscle aches.

I am on hormonal birth control and I always start my period 3 days into the placebo pills. This month (2 weeks after the second dose) my period started before I finished the hormones. About 3 days before they were done. I also had noticibly more cramping and the bleeding was light but a very dark brown. I haven't done anything for it yet. I am monitoring it to see if it gets better or worse. I believe that maybe the vaccine did something to my hormones because the morning after Vax #2 my breasts and nipples were sore.

Headache, 5 dime sized bumps on Right Butt cheek, menstrual period started up again 7 days after injection, diarrhea , itchy throat, sneezing, runny nose

Breast pain, severe fatigue, severe headaches, missed menstrual cycle followed by extremely heavy and long menstrual cycle

Pain and tingling in mouth. Pain in arm for days. Weakness for 13 days. Changes to menstrual cycle. Headache. Depression/irritability dizziness/lightheaded

1 day later - sore arm. 1 week out - intense ovulation cramping then two days later started bleeding heavily for approx three days - 2 weeks early for menstruation. Nausea and IBS symptoms every day since.

I started having menstral pain and ovary tenderness 24-48 hours after vaccine was administered. I have not had my menstral period in over seven months, since I am breastfeeding. It is unusual for me to have this discomfort, since I am breastfeeding and haven?t had a menstral period in a long time.

I am experiencing extreme abdominal pains during my menstrual cycle since getting vaccinated. I've never experienced this level of pain before. During each cycle, the pain has occurred for about 3 hours and then stops. During the time, it feels like I am being stabbed. The first time it occurred the pain was paired with diarrhea and the second time it occurred the pain was paired with vomiting.

Started bleeding profusely as if having period but an extreme version. It was 2 weeks prior to my scheduled period and my period is very regular and always arrives on time. Bleeding lasted for several days. I don't know if this will have lasting effects on my cycle or fertility going forward.

The vaccine has caused my menstrual cycle to be irregular. I have not received a period yet which has never happened to me. I am very consistent in my cycle and receive my period every 28 days. I am now on day 30 and still have not received it. Irregular menstrual cycles should be reported as a possible side effect.

Found out I was pregnant Feb 11th, 2021, the day before my second dose of covid-19 vaccination. Started bleeding February 22nd, 2021. Went to Emergency Room and was informed may be having a miscarriage. Persisted bleeding for a week. Visited an OB throughout that week and verified I was going through a miscarriage and was approximately 4-5 weeks. First pregnancy and only pregnancy.

Baby no longer had heartbeat on 20-week ultrasound. Was only measuring 15-16 weeks. Second dose of COVID vaccine given around 14 weeks.

I immediately started menstruation 5 days earlier than expected less than 1 hour after receiving the 2nd dose of this vaccine. Next I noticed my vision was slightly blurry and I was becoming lethargic. Within 12 hours I had a low grade fever, heart palpitations, and severe night sweats. By 24 hours I felt out of breath if I walked more than 10 feet away and I got extremely dizzy and felt faint if I walked too far. My period lasted 2 days longer than it should have and was heavier than normal. It is now 12 days later and I still feel fatigued, anxious, dizzy, and my hormones feel off. I definitely do not feel right. I get nauseous from the dizziness even though I have been drinking a gallon of water a day and not exercising. I am a very active person and I have been forced to be extremely inactive to keep all of these symptoms at bay.

I am 33 and trying to conceive, and I religiously track my menstrual cycle (periods, ovulation, tested hormone levels, and symptoms leading up to and following both). I have a 28-29 day cycle and it is as regular and consistent as the sun rising every day. In the days leading up to my period, I always experience tell-tale signs that my period is coming (specifically, back & leg cramping, breast pain & tenderness, and increased emotionalism/weepiness). I received the first dose of the Pfizer vaccine on 3/30/21. My period started on 4/16/21 following a normal/standard 28-day cycle. It was lighter and shorter than normal, but I ovulated at the expected time following that period, and it did not seem particularly unusual in any way. I received the second dose of the Pfizer vaccine on 4/22/21. Since that time, I have not gotten a period, nor have I experienced ANY of the premenstrual symptoms that I have experienced before every single period in the last 20+ years. I?m now on day 34 of my cycle, I have not had a period, and I am not pregnant. As I desperately search for answers on the internet, the CDC and other health authorities consistently say there is ?no evidence? that covid vaccines have any impact on menstrual cycles, despite tens of thousands of women with anecdotal evidence. This is infuriating and completely unacceptable. I NEVER would have been vaccinated had I known it would affect my cycles. It may be temporary, it may not affect fertility directly, but i have zero chance of conceiving this month, because there is no way to track and time my cycle. I am 33, desperately trying to conceive, and not getting any younger. To not tell women this prior to getting the vaccine, and to ignore it and deny it is even a problem, is absolutely criminal.

I have not had a period since receiving my first vaccine and am not pregnant (verified by blood test by my doctor). So far I have skipped 2 cycles. I also have restless legs and joint pain in my hips and knees.

I experienced a Miscarriage 03/22/2021 at five weeks pregnancy. I had gotten the second dose of the vaccine eight weeks before that. I was unaware that I was pregnant when I miscarried. I only found out I was pregnant four days before it happened. Due Date-09/18/2021 Pregnancy-Third
