is it possible that my girlfriend is pregnant if her back hurts and stomach cramps? We had intercourse march 22nd and her period started the next day. We used condoms and she was on birth control... shes been cramping for almost two days now and im really nervous and scared that shes pregnant. She also said that she has had brown and clear spots in her panties three times since march 22nd.... Is this spotting the start of her period??? she believes that what happened in her panites is not spotting though.... HELP
