"my girlfriend took plan-b 13 hours after we had unprotected sex. 
it was our first time and, to get better, she was in her fertile days. i didn&#039;t finish in her but we&#039;re freaking out anyway. 
the next few days were horrible, i was googling all the things about levonorgestrel and feeling a lot of anxiety. even the fact that she wasn&#039;t experiencing any side-effects made me more nervous. however, about a week later the period finally came. 
plan-b really works, it&#039;s all about taking it asap and trying to stay calm."
