Hi,
I just wanted to asked if what are the different causes of bleeding after sex?
I had Pap smear and STI blood exam last November and everything was normal. My partner was diagnosed of genital herpes and he didn't told of to me. The last time we had sex was december( protected). And since the last week December I had pink and sometimes brown discharge although the if had no smell, no pelvic pain, all was OK except the discharge. Please help me. Thank you

I hope you kicked your boyfriend to the curb. Lying about a STI, especially Herpes, is REALLY bad. I would go get yourself tested.

Was the sex rough? It could be mid-cycle bleeding. The brown is old blood, so that's likely just spotting.
