emergency contraception
"All I can say is relax ladies! It has over a 95% success rate. I had unprotected sex while I was ovulating and took the pill about 10 hours later. No side effects whatsoever for almost 2 weeks (Mind you I'm well above the "weight limit" for the pill). Then, my boobs started hurting so bad I couldn't bare it. I even had some spotting which freaked me out! It really messes with you, but in the end, I got my period! The longest 3 weeks, but it worked!"
