Hi, im 16. And i started my period on April 26th and 2weeks later on May 10th, i had unprotective sex and did the pull-out method, so he did ejaculate inside me. He had NOT previously ejaculated before and he did pee 30mins-1hr before we had sex. Ive done research and many people say that pre-cum doesnt contain sperm if he had not previous ejaculated or peed before having sex. But i wanted to consult with a doctor instead of websites. Up to this date, June 2nd, i havent gotten my period. I have noticed that my period is always pushed back from the exact time i should be getting my monthly period. Is there a chance of his pre-cum getting me pregnant? I may also add that ive been stressed out because i dont know if i am pregnant, so maybe its another factor why i have a delayed period. Thank you and please respond ASAP.
