okay so im 15 almost 16 year old female.ive have multiple sex partners( most of which i regret) and ive never had any signs of diseases or nething.well here my latest boyfriend..he was a virgin and we had sex.since that day ive been bleeding...basically like im on my period but that cant be.i was on it like a weer prior to us having sex and now ive been on it 2 weeks since we have.whats wrong? i go to a gyn next wednesday but im really scared.i know im not pregnant because they're putting me on birth control and i had to take a pregnancy test and it was negative but i dont know whats going wrong.his dick is really big,could that have anything to do with it?? he wasnt my first so it shouldnt have bled..especially this much...when we had sex it hurt well not like a real painful hurt but a lil bc his dick was bigger than anyone ive slept with before.we did do it a numerous amount of times in one day could that have something to do with it?? PLEASE HELP!!
