About 4 days after I had sex I started getting brownish discharge, the day after that I got light bleeding but it went away I still have a really light brown discharge. I got off my period about two weeks ago.what could this be?

Inplantation bleeding perhaps. Really hard to say, If you are pregnant you will have to wait to see if you have your next period.

That can be signs of chlamydia.. Do you get any blood when you have sex? And does it hurt?

It didn't hurt&&i didn't bleed. I just had brown discharge after sex. Is that normal
