Welcome leakyjim, you’ll find most of us here went through or is going through similar situation as you. It’s still too early to get results so Keep doing kegels. After 2 years of me doing them I had little success, so I resorted to getting AUS. That was a game changer for me. I don’t leak anymore but I wear a light pad primarily because I still can’t believe I don’t leak. One day I’ll get over that fear.
Good luck to you and remember the biggest battle is being cancer free.
