Anxious Mom 2 Be

I’m worrried I have ICP (intrahepatic cholestasis of pregnancy). My OB doesn’t seem to be too concerned that I have it. But I’ve been so itchy on both the palms of my hands, and soles of my feet, not including the itchiness I’ve been feeling all over. I really want to be tested ASAP, but they are making me wait to “discuss” with my doctor next appointment which is in 3 weeks, and I will be 32 weeks at that point. Should I be as anxious as I am, or should I trust my OB??
