Well she has a meal in her now, so you have a bit of time. Are you sure her dates are correct... perhaps the situation is less critical than it looks. I assume you can keep track of her weight (ok, you are not supposed to handle her, but maybe you could get a weight while cleaning, if you have to move her anyway?)
I know what you mean about not wanting to bug people. I HATE and DREAD such things myself. Just send him an e-mail as an "update," and then ask the question. Some pics, if possible would be good too. Bob Clark is a breeder - if he is like any other breeder, he loves seeing updates and pics on the progress of the babies he sends off.
Best of luck to you and the little one.
