Hi. Ok, I'm 20 years old, and sexually active about 5 days ago (we have been having sex regularly) when, I THINK, I was ovulating. Unprotected. So, now I'm experiencing slight cramping, and my breasts have been pretty tender for the past, say 3 days or so (They get slightly more tender everyday). Also, about 3 days ago I experienced nausea (at night) that I had no idea why I was feeling sick. I just started having a brown discharge yesterday that's not heavy, but not light either. I've gotten brown discharge before, before and after my period. But I got my last period the 18th of last month, and it is due for the 18th of this month.. I don't usually get brown discharge this early before my period. I am not on the pill. But, since I don't have many other symptoms of pregnancy, and I've never been pregnant before I was hoping someone might be able to suggest the chances that I am.
