Okay so I am fully aware that you guys CANNOT tell me whether I'm pregnant right now. All I want to know is how likely my chances are and if I should worry or not. I'm 16 years old and I'm on birth control. I take it every night between 11 and 1. Usually when there's a big time difference, I ll get brown discharge but I haven't had any of that for a few months now. Anyway! I had sex with my boyfriend tonight and he came inside of me! I didn't know he was going to do that because usually he pulls out. When I got home and sat on the toilet, it leaked out. I'm on the week of the sugar pills but haven't gotten my period yet. Should I be worried?
