Women’s Periods May Be Late After Coronavirus Vaccination, Study Suggests

Shortly after coronavirus vaccines were rolled out about a year ago, women started reporting erratic menstrual cycles after receiving the shots.
Some said their periods were late. Others reported heavier bleeding than usual or painful bleeding. Some postmenopausal women who hadn’t had a period in years even said they had menstruated again.
A study published on Thursday found that women’s menstrual cycles did indeed change following vaccination against the coronavirus. The authors reported that women who were inoculated had slightly longer menstrual cycles after receiving the vaccine than those who were not vaccinated.
