Long story short, about 2.5 weeks ago, I had sex with a guy using a condom. After that, he took off the condom and re-entered a few times before we decided it would be a bad idea to have unprotected sex. He didn't ejaculate inside me, but he could have possibly had semen left on his penis from the time before. I'm on bcp but I had missed one pill the week before. I took a Plan B just in case within a few hours of this encounter. Now I am having dark brown discharge (not enough to be a period) and I'm supposed to have my period within the next few days. I've had a little bit of brown discharge before a period before, but not often. But... Could I be pregnant and this is just implantation bleeding, or is this normal?
