Please someone help me. I have been on birth control for two months now. Last wednesday I started my period and then I went and seen my boyfriend. We had unprotected sex on that monday because it was the end of my period. Well during this time I had been taking birth control pills to get my period to stop sooner. I was taking two at a time. Now four days later I am having bad cramps and kind of sick to my stomach. Could this be cause because I was taking so many birth control pills? It also feels like my period wants to come but I don't think it is because of the birth control.
