Hello, I've been a little worried about my girlfriend lately. I'm naturally sort of a paranoid person, but I decided to ask for some assistance. Me and my girlfriend had intercourse about a week ago. We used a condom, (we always do), I pulled out right before ejaculation (we always do again), and she is on birth control (once again, we always do). So I'd say we practice safe sex. But, we were hanging out a few days ago, and she mentioned a slight light pink discharge after she wiped after going to the bathroom, which was on the toilet paper. It is very minimal and as she claims, hard to even see sometimes, but it keeps continuing the last few days, without pain she says. This has never happened to her before, and I'm a little worried. If these two events are connected, what could this mean? We've had intercourse a few times before and this hasn't happened. She had her period about 2 weeks ago, and should be expecting it again in about 2 weeks. What could this be?
