Hi Ive had sex three times in two and a half weeks. The first two times we used condoms the whole time and they didn't break. Third time he put it on half way through and it didn't break. I'm on birth control. About a week ago I started getting a brown discharge.I've had this for a week and yesterday should have been when I'd be on my period. It's still brown discharge at times. My stomach has been hurting a lot lately. I've been stessed with school and exams and eating unhealthy. Am I just freaking myself out? Or could I be pregnant?
