Menstrual period: It is not clear if you had unprotected sex before or since you normal period. Bleeding between periods or prolonged, eavy bleeding is not uncommon in young women and may occur occasionally. If you had heavy bleeding with cramps and clots, you may have had a miscarriage, but less likely. If you miss your next period, get a pregnancy test. And always use protection to avoid unplanned pregnancies.
