Hi, I'm a 16 year old female and I have recently had brown vaginal discharge. I sometimes get this a little before and after my period. I recently had unprotected sex with my boyfriend about 3 weeks ago and then 2 weeks later I had unprotected sex again. The first time he did the pullout method and busted on my stomach. The second time he had already ejaculated earlier but he went to the bathroom right after. That day and the next I had brown discharge. It stopped for 3 days but then came back and has lasted for 2 days. My period isn't supposed to be until later in this week. I'm wondering if this is normal or if this could be implantation bleeding. I am really nervous and need an answer ASAP!
