"my boyfriend and i used the pull out method but i was still super nervous because i knew i was ovulating. i know the pull out method is not always 100% effective so 2 hours after we had sex i went and bought plan b. i got my period 2 weeks later!! very effective as a backup plan! (also i am 165 pounds exactly so i dont think the whole weight limit thing or bmi thing has anything to do with the effectiveness of the pill)"
