FWIW, and ultrasound NOW would tell you if in fact your bitch is pregnant or not. SOmething that might be good for you to know.

Well the vet told me is best to wait untill she is at least 6 weeks and i will find out on my own and come back for xrays on days 50-55. So thats what i will do. And she has all signs, tho could be false pregnancy which i doubt. I have never seen her like this.
