"i&#039;ve taken plan b twice in my life. the first time was right after the &#039;incident&#039;, literally not even an hour after in the wee hours of the night we ran out to walmart, came home took the pill and went to sleep. can&#039;t say i remember anything crazy to that experience. i do remember my period came a bit early and the cramps were pretty severe and so was the bleeding. it took a bit for my period to get back to normal, but it did! this time around is a whole other story! i took it about three days ago, day of taking it was good, next day was good, yesterday midday i experienced nausea and vomiting, and now today diarrhea and cramps. suppose to get my period anywhere from 3-5 days from now."
