I’m 35 weeks pregnant and for the past couple weeks I’ve been extremely itchy on my arms and legs, especially later at night when I’m trying to sleep😩 i have no rash but I’m covered in scabs and marks from scratching so much it’s gross! Has anyone had this happen? Is it normal? I never had this happen with my other two pregnancies
