Pregnancy Info HOME

i am NOT ready to be pregnant.. i'm still a teenager. i was with my boyfriend and we've always been so careful. I won't even give him a blowjob without a condom. but we were just messing around and his penis was in just a little ways (barely) and he didn't have a condom on. i am on birth control because i have a septate uterus and skip my period for about 3 months. I missed my pill on the 10th, took two on the 11th and one on the 12th. we were messing around on the 13th. when he pulled out he noticed some cum on him but he doesn't know if he came at all in me, he says hes 98% sure he didnt. my question is, if he was barely in and if i'm on the pill, how big of a chance do you think i have of getting pregnant. unfortunately, this week was supposed to be the week i would have a period if i wasn't skipping it. i have been skipping them for almost a year now on dr.s orders. please someone help me. please...
