Levonorgestrel
emergency contraception
"Girlfriend and I had sex, condom broke and didn't realize till we finished. She was not on birth control and we were freaking out. She took the pill about 5 hours later, and for the next 2 weeks had some mild symptoms and light bleeding. Confirmed she was not pregnant a few weeks later. Pill does miracles, don't worry about the statistics (just there in case it happens to not work). If you take it before 24 hours, I'd personally say you have a 100% chance of it working."
