Frequent urination without infection.

My daughter is normal in the day time , but during night time( especially  bed time ) if she doesn't get sleep , she goes to washroom atleast every 5 mins, atleast 8 times in just half an hour , but during the day from morning to evening, I think she uses washroom , only  7 times approx ... And next morning when I ask if  urine urgency is there or not ,she will say it's normal. Note:( she had urine infection in June month). Even after urine infection was gone ,and culture test negative ,then also she suffered from urine frequency , ,ad it got settled after some days ..( scanning showed urinary  bladder wall thickning, 5,,mm in June and cystitis in June . ) ( kidney test is also normal ) But now this  urine frequency is happening two to three days every month . What is triggering this. controlling urine for long can affect bladder and trigger this frequency  .. Or allergy to food . Or ovulation Kindly  advise 🙏🏼 . ...
