I'm a 17 year old girl and I've been dating a guy for 2 years now. Both of us lost our virginity to each other and have not had sexual contact with other people. Im on the birth control pill, Yaz, and my boyfriend and I always use condoms, until recently. Lately, I've been bleeding a little when we're having intercourse (with out condoms) and I was wondering what could be wrong? I know that it's not my period, seeing as though I know when I start.

Is it possible that the sex is a little rough? This can cause bleeding during sex. There are other conditions that can cause bleeding during and after sex, but only your doctor can diagnose it properly.

It may be that you arnt getting wet enough and the friction is tearing you a bit, try some lube

Could be hormonal. Contact your gyn
