"hi everyone! i remember coming to these reviews the first time i took plan b so i thought i&#039;d share my experience. i&#039;m 18 years old 95 pounds and not on any format of birth control. i took plan b for the first time about 2 months ago after i had sex for the first time. we used a condom for most of it but there was about a 45 second time period were we did not have it on. i got really scared afterwards because i got sick the day after we had sex. being that i&#039;m young i assumed i was getting pregnant or something so i got plan b about 40 ish hours after sex. i took it and felt no symptoms honestly and i thought this meant it wasn&#039;t working but a few days later i got my period."
