"don&#039;t worry to much! plan b really works. i had sex with my boyfriend and the condom broke, i wasn&#039;t on birth control. it was also around the time i should have been ovulating. i took it within 2 hours. i had breakthrough bleeding a few days later that lasted almost a week. when my period was 10 days late i went to the doctor and had a pregnancy test and it was negative. they told me it can take another few weeks to get my period and that plan b screws up your cycle. my period ended up being about 3 weeks late, so don&#039;t panic! i went back to the doctor for another pregnancy test 3 weeks after the first (recommend by them to make sure) and it was negative again. be patient, it really works."
