Uti 1 day ago, when to call a doctor?

Yesterday I got a UTI (duh), I had SEVERE pains the first time I peed and shooting pelvic pains after, but since that I haven't had any other pain other than discomfort after peeing (the kinda discomfort where it still feels like you gotta go but nothing comes out)

Google no matter what article said that if you have any sort of pain during a UTI than it could lead to something worse, but does it still count if I only felt pain the first time and not again? Im really confused here and want to wait it out like a painless UTI but I really dont wanna risk something happening to my kidneys, should I call someone?
