Hi I am 15 years old and my boyfriend and I had sex for the first time about a week after my last period ended. We didnt have a condom but he only went 2 strokes in and didn't ejaculate. Since then we've had protected sex twice, but I am concerned because my period is now 20 days late. Now, I've always had irregular periods so I wasn't too concerned at first. I haven't experienced any pregnancy symptoms at all, but today I started having this weird brown discharge and have bright pink blood when I wipe. What is this?? I am so scared that I am pregnant please help!
