emergency contraception
"I took plan B a little over 24 hours after un-protected sex. For some reason, I was dumb and didn't think about the possible consequences of not being on birth control, not using a condom, and possibly ovulating. I got my period about a week after I took the pill. It was a really weird period, with dark blood, and eventually more bleeding than I usually have (with clotting). Right after I took the pill, I had cramps which I freaked out about, only realizing later that my body was getting ready for a period. I was nervous that it wouldn't work, but getting my period a week later was 100% of the reassurance I needed. Worth the money- my only regret was not taking the pill sooner."
