Could my dog be having puppies soon?

My golden is 58 days pregnant, today she refused to eat her dog food. She licked at it a little when i added chicken broth but that only lasted for a few licks. She'll eat steak, and chicken just fine by itself. She also kept crawling under things, coffee table, 4x4 ranger outside. And she keeps digging at the rugs. She hasn't pawed at anything during her whole pregnancy. This morning a yellow (snotty) discharge came out of her.... should i be expecting soon? like a day or 2?
