"i have never felt the need to review any medicine. however, i know i was super stressed waiting to see if this would work so i want to ease some others. i had unprotected sex with a random one night hookup and that night i did not take my birth control pill. it was 2 weeks before my expected period and i woke up the next day and took plan b within 12 hours after. and my period came right when expected! this worked for me and i know it works for many others! happy bleeding!"
