I had a very similar thing happen to me when I was awaiting Amnio results. I know it is so very stressfull waiting.

What I did was contact the Dr who did the amnio directly and got him to get me the name of the person doing the test and contact details. I then called, every single day. They were very understanding about me calling. I just hated waiting and if I called every morning at least I wouldn't spend the entire day by the phone.

Fingers crossed its sooner rather than later.
