"let me just start off by saying. breathe. chances are you are fine. my boyfriend and i had our little mistake on a saturday night around 8pm, i took plan b the next day at 10:30pm. i was experiencing terrible cramping in my abdomen and very sharp pains in my ribs and i was still feeling that even 2 weeks after the pill. i was scared out of mind. i was getting severe headaches and nauseous. i would even get minor heat flashes.. but let me tell you, i&#039;m not pregnant. i took a pregnancy test two weeks and 2 days after my accident and it came out negative. even got my period the same day. if i can give any advice, it&#039;s stop searching the internet. i know it&#039;s hard ladies, but it makes it so much worse. just make it two weeks, good luck!!"
