Thankyou so much for your replies... I really appriciate all the good advice. I took her to the vet this morning just to make sure everything was ok(there's a vet down the street that's opened 7 days a week!!!) He said she was just engorged, and to let the puppies nurse on those two as much as possible... temp was normal at 101.4, and he said all the puppies looked great. So yay! all's well
He just said to take her back if temp went over 103...
