Had protected sex. 2 days later, got my period. period is ending bc im lightly bleeding but ive had really bad cramps in past 2 days. am i pregnant?

Pregnant??: The chances of pregnancy are extremely small, especially if your periods are regular, and this was a normal period. If cramps are usual with your periods, and make you miss school, for example, you should consult your healthcare provider and ask about birth control pills, since severe cramping may be caused by endometriosis, and birth control pills may preserve your fertility options.
