Itchy and liver disorder

Anyone else very itchy all over and had blood work done to check liver enzymes? My    Levels of Alkaline phosphatase were slightly elevated and now I'm worried I have a blocked bile duct or something. Anyone have something similar happen? 
My doctor wants to wait until the bile blood work comes back in TWO weeks! I'll be more than 36 weeks by then. Oh well. Itchyness is part of my life now lol
