emergency contraception
"I had unprotected sex on the seventh. Took the pill about 2 hours later. I didn't experience any side effects at all after taking it. I usually start my period on the 15th, and I had been cramping a couple days before along with mood swings. On the fifteenth I started just having some light brown discharge, and this continued for two days. I was worried that it might be implantation bleeding, but on the 17th I finally started bleeding. The pill worked great, but I never want to experience the stress of it ever again."
