I had an itch in pregnancy that was not PUPPPS. No diagnosis was able to be made at the time, but I was advised to take antihistamines (Phenergan, one of the few that are safe in pregnancy) and this made life bearable for me. I continued post pregnancy, and I was eventually diagnosed with idiopathic urticaria (itchy rash for an unknown reason!) Your Dr should check your liver salts, or something, by a BT, but PUPPPS tends to be worse on hands and feet, and is not the only cause of itches in pregnancy.
