I want to have a normal delivery but worried about urinary incontinence. Is it common for women to face that?

I had 2 vaginal births and I did not experience urinary incontinence. I did kegels exercise during & after delivery and I think it does help to prevent the problems. I have a friend who had urinary incontinence after birth and she resolved it through practising yoga for 1 year and the condition has been solved.
