Women Experiencing Irregular Menstruation After COVID Vaccine With Heavier More Painful Periods

As per reports women are experiencing irregular menstruation after getting vaccinated against COVID with more heavier and painful periods.

Dr. Kate Clancy, an associate professor at the University of Illinois, tweeted in February that she’d been hearing about people who had experienced changes in their menstruation since getting one or two vaccine shots.

A colleague told me she has heard from others that their periods were heavy post-vax. I'm curious whether other menstruators have noticed changes too? I'm a week and a half out from dose 1 of Moderna, got my period maybe a day or so early, and am gushing like I'm in my 20s again.

‘A colleague told me she has heard from others that their periods were heavy post-vax,’ she wrote.

‘I’m curious whether other menstruators have noticed changes too? I’m a week and a half out from dose 1 of Moderna, got my period maybe a day or so early, and am gushing like I’m in my 20s again.

‘I’m on day 3 of my period and am still swapping out extra long overnight pads a few times a day. Typical for me at this time is maybe one or two regular pads (though extra absorbent, Always Infinity ones) for the whole day,’ she went on.

‘Does this have to do with the way the vax response is mounting a broader inflammatory response, possibly moreso because of the lipid nanoparticle or mRNA mechanism? Either way I am fascinated! Inflammation + tissue remodeling = extra bleedypants!’ she added.

Other women also shared their experiences after reading these tweets. Many women have been experiencing such changes in their menstrual cycles after getting vaccinated.

Some women shared that they have been experiencing heavy period flow and longer cycle than they had before getting vaccine shot.

There is no enough data to connect these menstrual cycle changes to the vaccine, so medical experts are not sure about it. Some studies have found that people experienced changes to their period after contracting the coronavirus.

One woman also revealed that she had 16 days bleeding after getting the jab.

‘I got J&J on March 15, then started my period about 2 days later — over a week early. It was heavier than normal,’ wrote one.

‘Two weeks exactly after shot number 2, my cycle started 12 days earlier and heavier than it’s been for the last three years,’ said another.

‘I am 3 weeks out from my first Moderna shot and started my period in the middle of a BC pack. That’s never happened to me in 12 years of taking the pill. I never even spot between periods,’ wrote one more.

‘My period following 1st Moderna dose came a week early and was the most painful I’ve ever had,’ tweeted yet another. ‘After second dose it came almost two weeks late and my cycle has been regular for years so I knew it was the vaccine but felt scared to say so.’ 

‘I thought I was going CRAZY,’ another answered. ‘I got the J&J shot three days before my period started and it’s now been…. 16 days of bleeding (normal period for 5 days then light but consistent bleeding for the rest).’

‘Me too!’ wrote one more. ‘I have an IUD and haven’t had a period in years, but am having cramps and spotting today (1st dose Pfizer was yesterday). No big deal, absolutely worth it, but strange!’

Monica Grohne, the founder of Marea Wellness, said her company has ‘been hearing from thousands of women about COVID & the vaccine affecting their periods.’

Some women also shared it on Reddit.

‘I had my first Pfizer vaccine on Friday, had sore breasts on Sunday and started my period yesterday. It’s two weeks early. I have been regular as clockwork on a 26-28 day cycle since they started 25 years ago,’ wrote one. 

‘Mine was on time but super heavy which is not my norm,’ said another. 

Dr. Clancy has also created a survey to investigate further. This survey was open for the adults who have received covid-19 vaccine and have had menstrual period at least once over the course of their life.

Experts say, they are not sure why women are facing such changes in periods and there is no enough data to know all about it.

Amesh A. Adalja, MD, Infectious disease expert and a senior scholar at the Johns Hopkins Center for Health Security in Maryland, suggested that any additional pain may be associated to normal vaccine pain. Some suggested that it may be due to stress.

‘There is no biologic mechanism that would account for [the] disruption of the menstrual cycle following receipt of the COVID-19 vaccine,’ Mark Turrentine, MD, professor of obstetrics and gynecology at Baylor College of Medicine in Texas, said.

He also said that bleeding changes did not come up as side effect during clinical trials. However, there is no enough data on post-vaccine periods.

As per a study published in the journal Reproductive Biomedicine Online, 25% women who had actual virus experienced some changes in their periods. This study was done on 177 patients and 19% had longer than usual periods.

A global support group on Facebook with more than 22,000 women is host to scores of discussions about period changes. One poll with long Covid-19 sufferers found more than 80% people experienced changes in their periods since being infected with virus.

CDC data reveals, that women have reported worse side effects than men after getting vaccinated. More than 7000 side effects were reported to the VAERS in February and 80% reactions were reported by women.
