Is it possible I am pregnant

So I kind of already no the answer to this but I jsut need some honest opinions because I think my friends are jsut trying to to calm me down.

Last weekend I had sex with this guy. We are not dating and we were a bit tipsy and didn’t think much of it. I am not on birth control and we had sex. He wore a condom but it broke pretty early into it. We had sex for about 45 mins at least. I’m not sure if he c*** in me because we were drunk but he didn’t tell me it broke until after and we continued too. It was the day after my period. My family is very fertile my mom got pregnant with two out of four of us on birth control and I am really scared I am only 17. What are the chances honestly. It’s super early to tell but still :(
