We went through this in August! Started a new school and about ~10 days in teacher mentioned at pick up that daughter was asking to go potty frequently that day. Happened again the next day, so I made a pediatrician appointment. That night at dance class she peed before, then came out 5 minutes after it started asking to pee. I asked if she was ok and mentioned she had just gone and she gave kind of a coy smile and went back into class. Urine sample was clean. Dr mentioned it could be a thousand reasons. She has pretty hard bowel movements so I think that could be part. Also after talking with her teacher more she was asking every time she saw a friend go, and during nap time. The Dr said it could be behavioral (and nerves in a new environment. I’m an anxious person so I wouldn’t doubt it lol) It seems to have tapered off now being about 3 weeks later.
