"this would be the third time taking this pill and i still get nervous. i don&#039;t remember how long it took me to take it the first 2 times as it was more than 2 years ago but it was definitely within 72 hours of having unprotected sex. it worked! no side effects and my period came. now, i had unprotected sex 3/18 and 3/19 and my boyfriend released inside me more than once. my period is expected 4/4 and i am hoping it still comes. of course, i am still freaked out although i know i should be fine. i took it right before the 72 hour mark on 3/21. i want a kid but not like this lol my fingers are crossed! it is most definitely the waiting game that sucks."
