"all i can say is relax ladies! it has over a 95% success rate. i had unprotected sex while i was ovulating and took the pill about 10 hours later. no side effects whatsoever for almost 2 weeks (mind you i&#039;m well above the &quot;weight limit&quot; for the pill). then, my boobs started hurting so bad i couldn&#039;t bare it. i even had some spotting which freaked me out! it really messes with you, but in the end, i got my period! the longest 3 weeks, but it worked!"
