Levonorgestrel
emergency contraception
"After breaking up with my boyfriend, I had a one night stand with a guy to move on. The condom broke, and we didn't notice until after we were done. I'm currently not on birth control, and I was on day 12 of my cycle which is normally 26 days, so I was definitely in my most fertile point in my cycle. After he left I went to CVS and bought Plan B. I took it about 2 hours after the incident occurred. I had some bad cramping for a few hours after taking it, but didn't get any other side effects. Anyways I'm very happy to report that I got my period today, 2 weeks to the day of taking plan b! I would've very likely have gotten pregnant if I hadn't taken it. If you follow the directions and take it asap, it'll do its job. Plan B really works!"
