"hey everybody! just wanted to say that this pill does work !! i took it 2 days before i was expected to ovulate and worried myself sick for the next week and a half. i experieced most of the side effects that were listed a few days after i took the pill. got my period three days eariler than my expected day; finally! please try not to stress too much over this , i have heard that plan b is 95% effective if taken within the first 24 hours!"
