I can’t tell if I’m pregnant or have a UTI 🥴

Well I did a stupid and had some *very brief* unprotected sex last week. He finished really close to my vagina and I was paranoid something would happen so I washed up real quick after that lol. But I was supposed to get my period 4 days ago and I always have regular periods... and I’ve been having trouble going pee even though it feels like I need to, barely anything’s coming out. That symptom lines up with a UTI but it also lines up with pregnancy symptoms 😬 and I know it’s still early to be worrying about pregnancy but I’m fuckin paranoid lmao and there’s no way I’m telling my mom or going to the dr haha I’d get the ass beating of a lifetime💀 help sis out w some advice pls
