Covid vaccines caused temporary menstrual changes in more than 40% of people with regular cycles, study finds

An analysis published Friday in the journal Science Advances found that 42% of people with regular menstrual cycles said they bled more heavily than usual after vaccination. Meanwhile, 44% reported no change and around 14% reported a lighter period. Among nonmenstruating people — those post-menopause or who use certain long-term contraceptives, for example — the study suggests many experienced breakthrough or unexpected bleeding after their Covid shots.

…

The new survey started in April 2021, around the time people began to report unexpected bleeding and heavier flow post-vaccine. However, these anecdotes were at the time met with the rebuttal that there was no data linking menstrual changes to vaccination.

That was both true and indicative of a larger problem. Individuals who took part in Covid vaccine trials were not asked if they experienced menstrual changes.

Why won’t the US medical establishment “believe women”? Covid-19 vaccines do not warn about menstrual disruption

As the National Institute for Health (NIH) stated in May 2021: “While anecdotal first person reports of menstrual changes in response to SARS-CoV-2 vaccines exist, these associations, and their long-term consequences, have not been investigated in a rigorous or systematic manner. Clinical trials for the Pfizer, Moderna, and Johnson & Johnson SARS-CoV-2 vaccine seem to have collected last menstrual period (LMP) data (to exclude current pregnancies), but have not collected menstrual cycle outcomes post-vaccine.”
