"i promised myself (like many others) that if this worked i would write a review just because i know how scary it is! honestly, i would not worry at all:) had unprotected sex (not on birth control) and he pulled out. i was still super scared (because i realized i was ovulating) and so i bought and took plan b within 2 hours of unprotected sex. this was on a sunday. the following tuesday i went and started birth control, which made things even more terrifying because it completely messed up when i was supposed to start my period. the weeks of waiting for my period were absolute hell, and trust me when i say things will be okay! this really does work! i got my period right on time during the second sugar pill! ladies do not worry !"
