My DH went to China for two weeks when I was 32 weeks pregnant - I was alone with a nearly 4 and nearly 2 year old and like you we have no family or support around. He was out in the sticks and we went days without any sort of contact. I ended up with some horrible bug and was the sickest I have been pretty much ever (coughing until vomiting every time I moved).

But we made it through. He didn't come home to a very happy wife, but I managed to drag us through. You will be surprised at what you can do. It is only 5 days, which isn't that long. 35 weeks isn't that likely for labour, do you have a friend that would be available to call JIC?
