Digital thermometer or IR temp gun? The latter is what you really need to know ground temps.
I would unplug the heat pad unless you have it regulated by thermostat. Too hot is worse than too cool.
Over 92-93F, which a heat pad, unregulated will get too in no time, can start causing problems for your snake. Even a little hotter = neurological damage. A little hotter than that and she dies.
People on here have tried to gently warn you, and even some not so gently. You keep saying you are doing X, but we are telling you need to do Y, Z, A, and B.
Your snake = your responsibility.
I want you to understand this is life or death for you snake. Not just heat wise, but if she doesn't start eating for you soon, she won't make it either. As stated earlier, she will NOT eat for you until conditions are correct.
