Puppps??

Me

I am 28 weeks and for 3 weeks now I have had itching it all started with a rash on the underside of my boobs I thought was heat rash but that rash has disappeared I now itch all over my body, occasionally I have a bump or a tiny cluster of bumps even pop up but no actual rash.. has anyone else had this? Was it puppps? Is it possible to have puppps and no rash? I’m so confused but I have itching everywhere hands feet arms legs belly sides, you name it. I have an appointment next week I’m going to talk to dr then
