helppp! alright i'm scared. i will see a doctor ASAP, but i just am worried and would really appreciate any opinions. alright, i'm not a virgin.. i lost my virginity when i was 15.. i'm now 18. anyway, i've had sex with two guys.. my first boyfriend, who was a virgin, and my current boyfriend, who has slept with one other person. i am on the pill and have been for about 3 years.. and i have never had sex without a condom - ever. however, last night my boyfriend and i had sex for the first time in a few weeks and it was very, well, vigourous i guess you could say.. i guess kind of rough.. but we usually do it that way. anyway, it didn't hurt at the time but this morning my vagina is sore and i have heavy bleeding... like i've changed my underwear a few times today and it just keeps bleeding.. a darkish red color blood. i don't understnad what's going on.. it's like my hymen got broken or something, but i'm sure that had already occurred. what could this possibly be from? i've read that chlamydia and gonnorhea both cause vaginal bleeding after intercourse, but can you get those STD's even if you always use a condom?? aaarrgh... this is worrying me so much.
