emergency contraception
"I had unprotected sex right on the day of ovulation. I mean dead smack on when I was fertile. I took the pill 2 hours later and had NO SYMPTOMS whatsoever. I had to wait a whole 2 weeks for my period to come and I was afraid the pill wasn't going to work since I was really fertile. But 2 weeks later, on the EXACT day I was supposed to get my period, I got it! So this pill works! Phew! Relieved!"
