Postpartum bladder issues

Hey guys. So this is happening to me. I have a dr appt with my dr Monday about this. My bladder just feel like it’s over working it’s self since I had my son. This my 3rd child & 3rd c section and I haven’t had issues with my bladder before. Like for example, I can’t hold my pee. If I try to hold it, I get this cramp feeling n my side hurts. I almost peed on myself driving from work trying to hold it. I’m doing kegels but I can only hold it for maybe 15 min or 30 then I feel this intense urge n it pushes out. But I don’t know what’s going on. My bladder feel like it’s it’s over working itself n like there is pee still wanting to go.

What’s going on? What can be done? Treatments? Is this permanent or temporary?
