Consult children about recurrent urinary tract infections.

Judging from the situation you described, there is no obvious abnormality in the structure of the urinary system, and there is no residual urine in the bladder. There should be no major problem. Looking at it from another angle, is the stool normal? Do you often clean your vulva with disinfectant?

Generally speaking, long-term use of anti-inflammatory drugs is not recommended, so three months of medication may not be able to prevent urinary tract infection for a long time.
