"i took the take action pill last year and i didn&#039;t research it or anything. i was really scared it wasn&#039;t going to be effective. my husband got it for me. i&#039;m happy to say this pill didn&#039;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&#039;ve so far just had headaches and breast pain."
