HELP ME PLS

so me and my boyfriend had sex (no condom) and he pulled out as fast as he could . but he feel he pre-cum in me and he’s not sure if he did or not tbh. I’m scared because my period is 2 days late and I don’t know what to do . May somebody please help and give me answers . and I have NO symptoms of pregnancy . I feel that it’s because I’ve been stressed and depressed but I don’t know . I’m really scared somebody give me answers to help !.
