"i took this pill 2 days after unprotected sex (july 16th) and bled a little 4 or 5 days later. i think it was just withdrawal bleeding not a period. so anyway august gets here and i still have yet to get my actual period. didn&#039;t get one all of august so i bought a home pregnancy test beginning of september because at this point i didn&#039;t think plan b had worked (although i had no typical pregnancy symptoms). anyway i took two home pregnancy tests and they both came back negative. this morning i started getting bad cramps and finally i got my period. now i know this pill is different for everyone but i&#039;d say unless you absolutely have no other options then don&#039;t take this pill. just get on birthcontrol or have the guy wear a condom. i am relieved i&#039;m not pregnant though."
