"i&#039;m writing this review just to ease the conscience of some of you out there but trust me this pill works. i&#039;ve had a to take plan b and this pill and they both did the job. granted with plan b i had less side effects but this pill i took 12 hours after having unprotected sex. i wasn&#039;t at my most fertile time of the month so that probably lessened my chances even more of getting pregnant but i took it just to make sure. right after i took it i was extremely exhausted and took a really long nap. the other side effect i had was cramping and an occasional headache but nothing too bad. i actually ended up getting my period a day early but the cramps were excruciating. other than that i was fine. the earlier you take it the better ladies"
