"ok so i&#039;m over 230 lbs and was super worried that plan b would not be effective (as i had unprotected sex and he came inside of me around the time i was suppose to be most fertile) just got my period!  hope this helps anyone who might be as worried as i was because of weight issues and pill effectiveness.  i&#039;ve taken this 3 times now and it&#039;s never failed me."
