emergency contraception
"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)"
