You also said "when I left it IN..."? I hope you realize that "UTH" means Under Tank Heat...meaning it does NOT belong IN the cage? Just checking...it's dangerous to run
UTH inside the cage, because your snake will likely spill some water (or just the humidity) & may die from electric shock...UTH is not designed for safe use inside a cage.
Note, thermostats are not the same thing as thermometers. Thermostats control the power, thermometers only measure whatever it is.

If you are turning the UTH off at night, how cool is his cage getting overnight? I'm guessing it's too chilly for him, but it depends on your ambient room temperatures too.
There are snakes that can tolerate a significant temperature drop at night (without getting sick) but BPs are not one of them. He needs temperatures between 78-80* on
the cool side and about (slightly below) 90* on the warm side...and he needs this 24 hours a day, 7 days a week...or he'll be getting sick.

It's still possible that he's going into a shed (hence the pinkish belly) but I'm not there, seeing your snake...so no guarantees. I sure do HOPE it's not a burn.
I have it under his tank and I had his cage set up before I got him. He was not in the tank when it got to 100 degrees. My UTH is not a thermostat. I am slowly buying better things for the tank when I can. I do not sleep in a cold room. I keep my thermostat on 80. I don’t have a thermostat on my UTH hence why I turn it off every 12 hours to let it cool down. I have 2 digital thermometers and hygrometers to make sure the temps are staying regulated. This is my first time owning a snake but my boyfriend has had many. He just never noticed a pink belly on any of his when they went into shed. He confirmed today for me though that he is probably going into shed because his eyes have a milky tint to them. Thank you for yalls advice it really helped. If it doesn’t get better I will take him to vet.
