37 weeks severe itching

Does anyone know what this could be? On Wednesday my hands started itching, nothing too bad. Thursday it was my hands and feet and it was bad enough that we went to the hospital. They tested me for a condition with your liver that causes scratching but it came back normal. Now, it’s Sunday and my entire body is itching. I was up from 2-4am scratching and crying because it was so bad. My feet, hands, legs, arms, back, belly.. everywhere. I have scratched my hands open, made my legs bleed. The only thing that soothes it is ice but I can’t just sit in a cold shower all day. I’ve tried creams and lotions, nothing works. I have no skin conditions, no new soaps or anything like that. My husband is forcing me to wear long sleeves, pants, and socks in this hot whether and he won’t let be alone that’s how bad it is. I called the doctor and she said every test they did was normal and if the cream isn’t working then there’s nothing left she can do. I see her tomorrow so maybe something will change but I can’t stand this
