So two nights ago my boyfriend and i had sex for the first time. I sucked him and then he put his penis in my vagina. We didnt use a condom. He didnt cum in me, or cum at all since it wasnt for very long. Im just learning that one can get pregnant for precum. What are my chances of getting pregnant? Im 16 and my boyfriend is 17. I have polycystic ovaries with a sort of regular cycle. My period had ended 4 days before we had sex. Any help would be great.
