I'm 17. 3 days after my last period finished, we were with my boyfriend, there was only genital rubbing (naked) and he didn't ejaculate. I'm being kinda paranoid and i want to know if there is a chance that i might get pregnant. Usually i have a 25 day cycle but it changes. Do i need to get a pregnancy test? When do i need to take it? And I haven't ever been to a gynecologist yet and i'm kinda nervous to ask my mom to take me to a doctor. I would appreciate any advice. Thank you
