Rash on belly

Victoria

Just developed a rash. It’s itchy at night. Sensitive when I’m taking a hot shower (sort of burns in hot water) I called my Gyno and they will see me Friday. I googled and it said PUPPP but I’m not sure that’s what it is for a fact. If so, then I’m relieved. If not, then I’m stressed😞 Anyone have something like this happen? 4th pregnancy and I’ve never had stretch marks or anything like this
