My beagle is pregnant, she has milk, discharge, is nesting a little, when do you think she will whelp.?

the first known breeding was on oct 23, but the male is in with her all the time, so I could have missed a few as I work all day. This was planned so dont think it was a whoops. There both akc, and they both are extremely great rabbit dogs. I want to keep some of these puppies because of the lines they both have. So like I said again this is a planned breeding and I dont need anyone talking about spaying. That will happen when I m done breeding. So now that thats out of the way,I wanted to ask do you think she will deliver before her estimated due date of dec 25. She has milk at all her , shes lost her stomac hair, I can feel the pups and see them moving. She has had the clear discharge for about 3 days and is tired and fallows me around steady. I checked her temp today and it was 99,5 not yet 98 when do you think the pups will come, any help would be great. thanks
