Possible Cholestasis

Ladies have any of you had Cholestasis? I have pretty severe itching but my labs came back normal. Just waiting on bile salts. I will be 37 weeks this Thursday and they could technically take the baby than if I do have Cholestasis. The problem is my Dr isn’t taking my itching that serious and from what I read I about cholestasis it sounds pretty serious. Would I be in the wrong to demand the baby to come out at 37 weeks because my itching is unbearable. I’m just wondering if the lab tests can be wrong. Thanks ladies
