emergency contraception
"First, the pill does work. I took it while I was on my period, so my period was longer and the cramps came back. YES, it does mess up your cycle for MORE than 3 months not just 1 or two months, but you know..every girl is different. This pill saved me but it will be a great idea to start birth control because plan b screws up your body. It was scary at first because of the bleeding and missed periods so just relax. Pill works great"
