I took the morning after pill july 27. 12 hours after the incident. I couldnt sleep the whole night just nervous and scared I was just waiting for the pharmacy to open. I felt all the side effects that showed vomiting, nasua, all of them it lasted for two days. The only one who knows is my boyfriend. and the thing is iknow the pill is suppose to push back my period but i was suppose to hav my period by the end of the month possibly the next day or by the last days of july so i have not recieved it. I have had cramps but not as often. Im scared and nervous all in one, 18 and just going to start college. If i had all the symptons does that mean the pill work? i read it can push back ur period from 1 week to four weeks im on two.
