Hi.. I'm 15 years old & I think I might be pregnant. I am 2 days late for my period. My boyfriend and I will have sex, but never long enough for him to ejaculate. To tell you the truth, he has never ejaculated before. We usually use condoms but I think since my last period, we haven't used anything once or twice. We have both also been stressing very much for the past two days because we are only 15. Could this be stress that is causing my period to be late, or am i pregnant? PLEASE HELP!
