Are COVID-19 Vaccines Causing Abnormal Menstrual Cycles?

There have been anecdotal reports of menstruation changes following the COVID-19 vaccines, reports the Chicago Tribune.

From The Tribune:

When Katy Fyksen got a heavy period a few days after she received her second dose of the Moderna COVID-19 vaccine, she didn’t consider there might be a link.

The 43-year-old Plainfield woman hadn’t had a period in over a year and a half because of her Mirena IUD, so the sudden red flow was a surprise...

For Fyksen, the unexpected period was over in about seven days, and she said that even if it was related to the vaccine, it was worth it.

“I’m just very happy to be fully vaccinated. If that’s the worst of the side effects I have, then we’re good with it,” she said.

Dr. Kathryn Clancy, Department of Anthropology, University of Illinois at Urbana-Champaign and Katharine Lee, a postdoctoral research scholar at Washington University School of Medicine, are now conducting a study:

You are being asked to participate in a voluntary research study. The purpose of this study is to understand the menstrual experiences of people after they have been vaccinated for COVID-19. Participating in this study will involve completing a secure online survey which takes about 15-20 minutes. Risks related to this research include the potential to feel uncomfortable answering questions about your body and health. Benefits related to this research include being able to share your experiences and contribute to an often-overlooked area of health research.

From The Tribune again: 

Clancy and Lee were inspired by their own experiences with abnormal menstruation following their inoculation, and wanted to document the experiences of others. They said they initially expected 500 people to respond to the survey; instead they hit that mark in a few hours.

Clancy outlined her personal menstruation experience in a February tweet, after receiving her first dose of the Moderna vaccine. Hundreds of women and people who menstruate replied in the comments with their own experiences.

One Twitter user wrote, “I haven’t had a period in years and I’m about 3 weeks out of my second shot and I’m gushing blood I freaked out but now I see I’m not the only one. This is crazy.”

Another responded, “Two weeks exactly after shot number 2, my cycle started 12 days earlier and heavier than it’s been for the last three years.”

“I ended up finding a lot of people with similar experiences,” Clancy said. “But also, to be fair, a lot of people who were like, ‘Really, I noticed nothing,’ and some people who said, ‘Actually I had the opposite, where I’ve had a later or lighter period.’”



  1. It always astounds me when we hear of these stories of people experiencing severe or unexpected side effects that are not well understand, and they still say it's worth it to take the vaccine.

    In the case of this woman, I am baffled how she can assert it's worth it when it's not even clear yet what it may have cost her. For all we know, this may be causing infertility in some women if it's severe enough.

    The problem with these gene-based vaccines is they can get into parts of the body that a virus would normally not get into, and result in an autoimmune response. Bloodclotting in the brain is one good example; an actual respiratory virus wouldn't make it there, but genes from the vaccine are through the bloodstream.

    In the case of these woman with abnormal periods, I am very worried the cause is from the vaccine getting to their ovaries (which would never happen otherwise) and causing an autoimmune response against the ovaries. One women commented about gushing blood... are all her ovaries getting destroyed by the autoimmune response? And there's no reason this can't happen in men either, but the signs won't be as obvious.

    1. It is not a particularly exciting explanation, but cognitive dissonance would be a standard explanation for this. In this case, people have to say they are happier about getting the vaccine in order to justify the decision in the face of a higher cost (or lower total benefit). There should also be a tendency of these people to increase their assessment of the danger of the illness. I am not sure at what point this turns into full blown Stockholm Syndrome if it has not already.

    2. I agree, but it may even be more absurd. The shots might not be providing any protection whatsoever. The CDC claims to be looking into "breakthrough cases". See here:

      5,800 guinea pigs that received the shot got covid, and 74 of those 5,800 died of covid. That's 1.27% of the "vaccinated" that did not survive the infection.

      To me, that means that the shots are not providing ANY protection at all. An unvaccinated person has just as good a chance of recovering.

      I smell fraud.

  2. What's even more concerning is that my spouse, who works in an ER and has not gotten the shot, has also been experiencing abnormal menstrual cycles. Obviously she has been around plenty of people who have gotten the shot. We've heard other accounts of this as well. Are they shedding? What the hell is going on???

    1. Unfortunately there have been many reports of this (nonV’d women’s cycles being drastically affected after spending time with V’d people). There are social media accounts highlighting this with hundreds of testimonials, which have been quite graphic and disturbing.

      Astonishing that the ‘science’ discourages caffeine, Tylenol, deli meats, etc., yet encourages an experimental jab for pregnant women.

  3. Good news: I have not gotten the shot, and have not yet started menstruating. Will keep everyone posted.

  4. What's been your personal experience Wenzel, or are you post menopausal?
