Is pregnancy a possibility?

I had unprotected sex about a week after my last period ended, but he didn't *** inside me (I know you can get pregnant off of pre-*** though). Within 24 hours I took the pill Plan B and experienced basically my period all over again - I bled for a week and a half. My period has always been irregular (I recently went three months without having my period) so being late isn't really anything new to me. But I was just wondering if it was at all possible that I could still be pregnant, even after taking Plan B and bleeding afterwards?

If you had your period after takin g plan B more than likely you are not pregnant. But if you are concerned youo can take a test about 2 weeks after the unprotected sex. You should also consider getting on a regular birth control if you do not want to get pregnant as plan B should not be used as birth control. Good Luck
