Potty trained toddler having accidentsu

My daughter has been potty trained for awhile but between today and yesterday she has had quite a few accidents. About 5. Even it's only 10am and she wore a diaper all night and then I had her pee on the potty this morning and then before I took a shower she pooped on the potty. I just got out of the shower and she had an accident in the hall. I am most likely going to bring her to the walk in clinic to check for a UTI but could it be anything else? I just dont know why she would poop fine but keeps having pee accidents. She doesnt have a fever. Also I ask her if it hurts to pee and she says no. I've asked her a bunch of times she says no
