emergency contraception
"I took this drug on May 26 following an unprotected incident.  He didn't ejaculate inside me, but I took it as a precaution 17 hours later because it happened on day 13 of my cycle. Eek! I didn't experience any side effects until a week later, when I received cramping. Weird cramps under my left and right pelvic bones that burned. I also had severe anxiety and depression and dropped 13lbs. It was a nightmare. I received my period nearly two weeks later, just 2 days early from my projected start date. It was heavy with heavy clots and lasted a day longer than normal. That being said, my following period in July was 9 days late and I hadn't had sex since. Be warned that the pill can mess up your cycle for a few months after taking it!"
