Hi, I used to be the same way - always in to big of a hurry to pee and I paid for it - holding more urine stretches your bladder and for pockets on each side that holds urine and having toxic urine on board can tear your bladder up due to infection. The only fix is surgical. It's called an A and P repair. It was a painfull surgery that left scars up in my vagina and the scars hurt, especially with having sex...... but that is much better theb getting toxic and dying.
See your OB, drink lots of fluid to make you feel the urgency more and you will break the habit of holding it in.... DRINK lots og cranberry juice as wel.
