Hi. Now im already 38w pregnancy. Been suffering of rashes and itchiness at tummy and legs since a week ago. Anyone knows how to reduce this itchiness?

I’ve been thru all sleepless night. And this itchiness become worst day to day. I went to hospital, and the doctor gave me hydrocortisone cream. After using that, it became more worst so i stop using it. Im having contractions since 3 days ago but still its a false contraction. What should i do to reduce this itchiness ?
