Levonorgestrel
"I took the take action pill last year and I didn't research it or anything. I was really scared it wasn't going to be effective. My husband got it for me. I'm happy to say this pill didn't really have any scary or painful side effects the only thing I felt was maybe little cramps breast pain and that was it. I got my period 3 days after when I was supposed to get it, even though this pill is only effective during 72 hours (3 days) I took it the 4th day and everything felt normal. I took the take action pill last year July 4, 2014. I have recently took it again 2 weeks ago and I've so far just had headaches and breast pain."
