What can I put on my uteatha so I don't feel le I have to pee while sitting on the car on a trip?

Depends. Some people develop bladder instability or urethral problems when sitting. Your doctor can prescribe a pessary which could help if you are having weak supports in the pelvic area. Otherwise I would suggest a complete physical to figure out why you are having urinary issues during car trips.
What? your what? Please have someone help you with the question so we can potentially provide you with a helpful answer.
