I feel like poo. Everything was going fine, now I feel like I'm crashing

I have to take it super easy, so to make sure that I don't go into early labor, and to top it all off, my legs, feet and arms are itching sooo bad that I can't sleep anymore. Its driving me nuts!!! I have been reading up on Obstetric cholestosis, and I'm hoping that it's not the case. Don't really know how to go about asking MW either, since I called the nurse today, and she didn't really seem too concerned. I would rather have the test to make sure, but really don't think that they will consider it. I guess its something that is usually overlooked, seeing as itching is common during pregnancy and all, but mine has just started recently.
I just don't know what to do anymore
