"i had unprotected sex and took plan b within 8 hours. i started feeling sleepy &amp; i had a headache. i had unprotected sex again (this time pull out method) two days after, took another plan b. started feeling drowsy again. i got my period 3 days after thank god. i will never take that risk again. i highly recommend birth control! its much cheaper! $50 for one pill is alot. i decided to get on birth control pills and i love it, its wayyy better than plan b."
