So i've been on birth control for over two years. i stopped for two weeks had my period then got back on due to not getting a prescription filled. I take the three month birth control where i don't have a period for every three months. the first time I ever got on this, i had brown discharge. A few weeks ago me and my old partner had unprotected sex while i was on the pill. now i have a brown discharge it is heavy but it's turned into a bloody discharge that was just as heavy but it's slowly dying. the brown discharge has happened for a week and the blood has been happening for like three days. what is going on? i'm 18 and he says he didn't cum inside of me.
