Emergency Contraception
"I took this about 7 hours after unprotected sex and was really nervous about it not working because I read something online about this not being effective for people weighing 175lb+ DO NOT WORRY ABOUT THIS. If you take this within 72 hours you will be fine. I had cramps and was nauseous for the day after I took it (my body is not used to these hormones) and other than that, I started my period about a week earlier than I was expecting."
