The vet thinks that she absorbed her pup bc when we had an ultrasound earlier he saw two sack, but felt that they didn't look like they had enough fluid in them and said then that she might reabsorb them. He felt around on her today and couldn't feel any pups so he was pretty confident that that is what happened.
The really weird thing is this happend to me on one of my pregnancies. Oh well life goes on. I'm so sad. but when it's meant to be it will happen.
