"i&#039;m 19 and have taken this 3 times in the span of 1 year and its worked like a charm every time. i recently took it last week because i had unprotected sex and the guy came in me all the way and  after i found out that i might have been ovulating. i took the pill maybe 3/4 hours later. i got my period yesterday and i could not be happier! i was so worried thinking about it and googling endless possibilities of pregnancies 24/7 but seriously don&#039;t even stress it. plan b has worked for me every time!"
