"this pill is very trust worthy! i am 17 years old, turning 18 and had unprotected sex with my boyfriend for the first time. he had gotten off inside of me around 10pm. the next day i went out and got plan b and took it around 5pm and took the next pill 12 hours later. i started researching and freaking out and i realized we had donei t on the exact days i was supposedly ovulating! thank goodness my period started two weeks later on the exact date it was suppose to. i had minor stomach pains and spotting from the pill a few days after take but nothing major. stop stressing, the pill works."
