My boyfriend and I just had sex for the first time on 5/8/12. My period ended the day before. We didn't use a condom but he did not finish inside of me, it wasn't even close. I'm on birth control and take it on schedule. I'm worried because of the pre-cum. I haven't had my period since then. I took my last birthday control pill on Saturday and have yet to have my period and it's now Wednesday afternoon. I have been stressing out about my finals and such, so is it possible I'm pregnant? Answers please.
