so my boyfriend and I had unprotected sex last on September 30... please, i really don’t need a lecture, i know it was stupid. we were both virgins & everything. it only lasted about 7 minutes because it was kind of painful for me.. i know you can get pregnant from precum, but i know he didn’t ejaculate, and i took plan b within 15 hours of sex. I can never track my periods because they’re so irregular so i never know when i’m ovulating either. my last period was September 17, and the one before that was June 20. Please, ease my mind a little. what are the chances i’m pregnant.. thank you all
