I have a female min pin that had puppies three weeks ago. She did real good until a few days ago. She has diarrhea real bad. Her stools are dark and runny. Now today she can't eat and is laying around.

I could say that the delivery took a lot out of her and she hung in there to get the pups started, but I think you had better get her and the pups to the vet (the pups because they should be with her) otherwise you are going to left with the pups to feed on your own and take of. Have you called a vet to see what they say about her condition? I don't know why you would wait around to get answers here, which may be sporadic at best because we are all volunteers here and there may not be an animal technician on for a while.

vet. Vet. Vet. Vet. Vet.

I can't say that enough.

If the stools are runny then the nutrients she is eating are not being absorbed, this means the milk she is producing for the puppies will have little to no nutritional value. Then there is the risk of dehydration... vet vet vet.
