I thought the worming every day was a typo!!! Please call your vet and make sure the wormer you are using is safe for pregnant moms. I have never heard of worming every day.
Here's a great link. Read as much information as you can so you will know if there is a problem. Begin taking her temperature at the same time morning and evening around Day 55 and you should be able to predict when you need to be on the alert.
After reading the first part of the link go down and continue clicking on the subjects, it will take you all the way through weaning the pups.
