emergency contraception
"I had unprotected sex a few days (2 or 3 days) before my expected ovulation. The condom broke, so if I was fertile, I was definitely going to be pregnant. But we went to Walmart and bought the plan B; I took it after about 3 hours because I had been reading reviews and got scared about the potential side effects. But I didn't get any horrible side effects from it; only light cramping at random times. I started bleeding about a week afterwards. It didn't feel like a normal period. I'm pretty sure it was just my uterus shedding itself. This lasted a week. It was kinda heavy at first and began to taper off each day that went by. And there was only light cramping  (thankfully). My normal period came after 4 weeks. (So it was a week late.)"
