"i have taken this before in my life. i can&#039;t take regular b.c. pills because even the lowest dose effects me very badly. i go crazy in short. i don&#039;t know many other people that it effects this way. i took plan b recently the 4th day after an incident (this decreases the effectiveness being this late). i bled lightly for a month and then it stopped 4 a few days and i got my period. it always seems 2 effect me intensely. i&#039;m bloated feel general malaise it increases the freq. of my migraines,i gain ~10lbs i am so tired and on an intense emotional rollercoaster for a mo. to 2 months after. this is similar to how regular birth control effects me. i&#039;ve never gotten pregnant after using it. so worth all the side effects. it works and side effects are temporary. worth it"
