emergency contraception
"We had a comdom mishap on September 27, and I took the pill 12 hours later. I didn't have any side effects, and I got my period, right on time, October 2nd. Maybe it was just not a fertile time for me, I'm not sure. I know I was done ovulating so I probably wasn't even fertile anyways, but needless to say, I went and got birth control and I'm taking it after my period is over."
