Pelvic floor and PT after c-section

Hey ladies! I am 8/9 weeks postpartum after having my second c-section. My doctor wrote me a script for pelvic floor therapy and PT. I am pretty clueless of what pelvic floor therapy entails. Will that help with ab separation at all? I don’t have any issues with leaking or anything to do with the bathroom, but I suspect my muscles are weak due to some pain during sex. If anyone has done either therapy for c-section recovery please let me know how it went and if you think it’s worth it!
