Menstruation Questions

When sexual intercourse occurs and pregnancy is established, menstruation ceases. Sexual intercourse during menstruation is not a problem, but pregnancy is just as possible as when you are not menstruating. However, the risk of infection is increased because the vagina is more easily scarred due to the blood collecting in the vagina, and if menstrual blood flows back into the uterus, bacteria can grow and the risk of endometriosis increases.
