Possible UTI?

So a few days ago i noticed it was burning when i peed, and so i told my mom to help me schedule a doctors appt so i can get it checked out and see if it’s a uti. but the past few days the burning has stopped and i have been feeling a bit of abdominal pain with diarrhea. my mom doesn’t want to schedule a doctors appt because it costs too much money. is it possible i don’t have a uti? i had burning but it went away, i have been peeing a lot, i have abdominal pain and diarrhea.
