I'm 17 years of age and I've just had sex for the first time. It was during my fertile week and we didn't use a condom. He pulled out before he ejaculated but I'm just wondering on the chances of pregnancy from pre ejaculation? I took the morning after pill but I'm still terrified! I'm not due my period for another 16 days and I don't think I can wait that long.... Have you any advice or is there anything I could do to find out? Does anyone know how much of a chance there is that I could be pregnant?
