So a week ago my boyfriend and i had unprotected sex but he was only in me for 15 seconds. Precum was present and the day before i was late by 12 hours on my birth control pill. I was suppose to get my period yesterday but i havent yet. I'm worried that I'm pregnant and I'm having some white/clear discharge in my underwear. Does this mean I'm gonna get my period soon? What does this discharge mean?! I'm only 15 and I'm worried! Please help!
