"after being on birth control for 4 months and never missing a pill, the night i had sex for the first time i had forgotten to take my pill that day. after having sex, we realized the condom had broke and i tried not to freak out. the next morning i went to the pharmacy and bought plan b about 10 hours later. i took it and it was the worst month of waiting for my period to come because i had just gotten off my period when i had sex. it took forever but 3 weeks later it finally came 1 day early and i am so relieved!!! plan b is the best 50 dollars i&#039;ve ever spent."
