Levonorgestrel
"Hi to all girls, who are terrified about getting pregnant! I want to share you my experience: I had sex with my boyfriend on my ovulation day (according to my bbt chart) and the condom slipped off inside me. We both had panic and went to a pharmacy to buy the morning after pill. I took takeaction (levonorgestrel 1, 5) after 30 min. unprotected sex happened. The last 2 weeks were the longest of my life but finally I got my period one day earlier than expected. The side effects I experienced were: heavy bleeding (the first two days), tiredness (disappeared after 5 days), abdominal pain (one week before I got my period). My period is heavier than usual and with a lots of cramps but I am not pregnant. Good luck to all of you!"
