somethings wrong with my snake

[gts4749]

I was hoping I could get some help on what is wrong with her and what to do to help. She's got brown spots on her belly scales that from what I've researched appear to be scale rot? She also has some reddish pink tones to her belly which I understand could mean she's going to shed however her last shed was about 2 weeks ago. I turned the uth heater off in case that was causing burns. Using repti bark as a substrate which I took out and rinsed thoroughly in hot water about 3 days ago. It was still a bit damp when I put it back in. Sorry for the rant I just want to give as much info to help.
