UTI???

So I kind of have a suspicion I have a UTI just because my “tank” never feels empty after going pee, and something new I’ve noticed I’m not sure if it has anything to do with the UTI but I get this sharp pain in my lower left abdomen and whenever I push to go pee or I’m rushing to the bathroom to push to go pee I get this sharp pain in my lower left abdomen but once I’m done peeing it goes away.. it safe to say I should just go to the doctor? (I planned to go to the clinic on Thursday anyways)
