Thank you for your query.
I am of the opinion that you should wait and watch. If you feel that she is not wet then the best course would be to keep her engaged so that her mind is diverted to other things. However ensure that she passes urine at regular intervals and her personal hygiene is maintained.
Despite the above mentioned approach she still complains then the best course would be to get an ultrasound
done and then see a doctor.
I hope I have answered your query to your satisfaction.
