We did use a condom but the problem is it broke

Hey guys so me and my boyfriend had sex yesterday night but I'm really scared right now , yes we did use a condom but the problem is it broke , so it happened while I was on top of him with my back facing him and I have to say I wasn't that much wet , before he could put it back in we both heard the condom break. (Btw he did not cum)but I did feel something wet that came from his penis , it was around my butt hole and I think it went around my vagina , could this have been precum ??? If so could I be pregnant? I'm really scared idk what to do!! I wasn't looking but he said I should have to worry because if anything it got on the top but I'm still scared
