Menstrual cycle alterations post SARS-CoV-2 vaccination

Abstract

Many women have reported changes in their menstrual cycles since receiving a dose of the COVID-19 vaccine, such as variations in its duration, absent or painful menstruations, heavy or scanty bleeding, and bleeding between menstruations. Until now, menstrual cycle disturbances have not been officially considered a side effect of the anticovid vaccine. There is need to broaden and deepen studies on this topic.
