"girls, if you think it&#039;s not going to work stop sweating it. my boyfriend and i had sex while i was ovulating and the comdom broke and about 9 hours later we got plan b and i took it. i got my period 2 weeks early and broke out pretty bad and had terrible headaches but it&#039;s better than pregnancy and taking care of a baby when you aren&#039;t ready. don&#039;t worry it works"
