The waiting is the worst part of all of this!! But fact is the apple won't fall until it's ripe so just clear any appointments you might have that will take you out and hang in there. She/you should be sleeping in the room where her whelping box is now because all too often, bitches whelp overnight so you need to be right there. I'd not bother with the vet or risk her picking up infection (sick dogs go to a vet) at this point. If once she starts having strong contractions, pushing hard, but getting nowhere for more than 1 hour (each delivery) then is the time you need a vet.
Best I can offer is 'calm down dear'

ps I read books - frightened me to death!! Do you have a mentor to hold your hand through this?
