COVID has affected countless aspects of our lives. For many people who menstruate, one of the pandemic’s effects has been on periods. People have reported changes to their menstrual cycles after having COVID, from the timing of their period, to its duration, to bleeding (a heavier or lighter flow).
Meanwhile, many people have reported changes to their menstrual cycles after COVID vaccination. The largest study yet on this topic has just been published, finding that 42% of people who regularly menstruate reported a heavier period after COVID vaccination.
