"all i can say, from my experience, the pill is not very effective. from the other reviews i read, it seemed like it worked for most people. my boyfriend and i had unprotective sex 4/25. i took plan b within 24 hours. figured i would be okay. missed my period. took a pregnancy test and yes... it was positive. maybe if i would have taken it sooner than 24 hours, i might have gotten lucky. not this time."
