Survey study, 2022

Does COVID-19 infection change women's menstrual cycles?

Two-thirds of women's cycles stayed the same after COVID-19 infection, but one-third reported changes including altered bleeding or cycle length. These changes appeared to be temporary.

Early or limited evidence 590 women (general population and healthcare workers) surveyed online

What they did

Web survey of 590 women (some who had COVID-19 infection, some who were vaccinated), asking about menstrual cycle changes.

What they found

Of 228 women with COVID-19 infection, 67.5% (154 women) had unchanged menstrual cycles. Menstrual bleeding decreased in 14% (32 women) and increased in 18% (42 women). Among women with severe COVID infection, 20% had heavy bleeding. Of 436 vaccinated women, 66.5% (290 women) had normal cycles, 4.8% (21 women) had decreased bleeding, and 4.1% (18 women) had increased bleeding.

What it means for you

COVID-19 infection probably does not cause major lasting changes to menstrual cycles in most women. The study was online and relied on self-reported information, with no control group. More research is needed to understand why cycles changed in some women.
