No she is not ok. You need to get your Yorkie and her puppies to a vet, the sooner the better. If you do not get her to the vet fast enough, the Dehydration will kill her, if she is in fact Dehydrated.
You should have already taken her and her puppies to the vet, 24-48 hours after the puppies were born, to have her and her puppies checked and get her cleaned out but you said nothing about doing that.
Emergency Vets are open 24/7. Get off your computer, call your Regular Vets Office and they will have the name and phone number of the Emergency Vet they use on their answering service.
Make sure you keep the puppies really warm, because they can not retain their own heat yet and if the get the least bit chilled, the puppies will die.
This is not something that can wait. Take it very seriously, if you do not want your Yorkie and her puppies to die. When the vet says it is safe, have her Spayed, so this NEVER happens again.
