emergency contraception
"I had unprotected sex a few days before my period and took plan b the same day. I was freaking out from reading all these crazy reviews and stories of it not working. It worked for me I'm over 185 lbs and over the "weight limit" for effeftiveness. 2 days after the pill I had severe cramps and threw up, then the next day more cramps and a very heavy clotted period. Then a normal period the next month. Personally it worked for me but I took it the same day."
