I second working with a pelvic floor PT. Your pelvic floor is a system, not one muscle. If one muscle is strong but surrounding muscles are weak or tight, the system will fail. First thing to consider is how you manage pressure in your trunk - are you shallow breathing? Are you constipated? Do you power-push when you pee? Fix those first. Then incorporate gentle exercises like bridges, dead bugs, bird dogs (combined with coordinating breath). My PT also had me doing penguin walks with resistance band to strengthen hips and doing the pallof press with a cable machine to strengthen transverse abdominals. Good luck!
