Question for you ladies about PT

Body: 

Hello to all,
I am going to go to PT for the first time today. Its where my insurance has sent me so I dont know if they specialize in the pelvic floor muscles. When I talked to her on the phone she said she thinks she can help so we will see. I am mainly concerned with my pc muscle strength and isolating the pc muscles. Does anyone have any advice on what I should expect or ask? I have never been to a pt before so this should be interesting. I just want to get the most out of it. Thanks for you input.
Patty
