"first i&#039;m going to begin this by saying it works. i had unprotected sex on the 29th of september. it was my first time and he did not go all the way but i was still scared! i took the pill 25-28 hours after and didn&#039;t notice any pain or anything, only brown discharge which freaked me out thinking it was implantation bleeding. also, just so you know i took the off beat brand of plan b, which scared me even more that i thought it wouldn&#039;t work since it wasn&#039;t the correct brand name, lol. until the 4th night after taking the pill. i went to lay day to go to sleep and was up almost all night with cramps and achy legs. i woke up on the 5th day after taking the pill and notice blood dripping down my leg! don&#039;t freak out like i did!"
