After widespread concern that Covid-19 vaccines have been messing up menstrual cycles, a new study has found that periods are slightly and temporarily delayed by the inoculations.
Women who had been vaccinated, on average, experienced just under a day’s increase to their usual menstrual pattern, according to U.S.-government funded research published in the Obstetrics & Gynecology medical journal. The study comes at a time when some women have complained about off-set cycles, along with heavier and sometimes painful bleeding. It found that those who had both vaccine doses during the same cycle saw delays to their period become more pronounced at two days later than normal.
