Plan B
"I'm gonna share my full story to try to bring relief to anyone freaking out. I am 18 and my boyfriend is 19. We're clearly not in a place to be parents at all. We had sex with a condom a week ago and as he was pulling out it slipped off spilling who knows how much in me. I immediately took plan b. I got my period a week later and two weeks earlier than it should've been. But my period was weird, it started off brown (which it normally is at the end not beginning) and it was very light, me freaking out took to the Internet. I was very nervous that this could be implantation bleeding instead of my period because it met the qualifications of implantation rather than a period. I waited it out and now my period is regular. Hope it helps."
