Last month, I had sex for the first time ever. My boyfriend and I had sex on three different occasions, and all three times we used condoms. I am now, ten days late for my period, and am afraid that I may be pregnant. I haven't taken a test yet, I plan to wait until friday on the chance that I might start this week. I am sixteen years old, but under a lot of stress. I do high school and college classes and have several mid-terms due this week. I am involved in a lot of extra-curricular activities including nhs and student council, i'm from a very small town, so if I did end up being pregnant it would be the biggest scandal in a long time. I hope that it is only stress causing my period to be off, or possibly just some side-effects from it being my first time. Is that possible? I asked a friend and she told me not to worry because she has had unprotected sex many times and not gotten pregnant, but I still can't help being terrified.
