Sorry I didn't reply sooner
It has been about a week and a half and we still aren't sure. At her first vet visit her temperature was normal. He didn't do any further tests only palpated .
She went back to the vet last thursday for an upper respiratory. At that point her temperature was up to 103 degrees. He did palpate again and still couldn't feel anything though he stated that if she was pregnant the babies may be hiding under the ribs. He no longer seemed to think that an infection was a problem.
I did ask about an xray but he felt that if he couldn't feel the babies then they wouldn't be far enough developed for an xray.
So we still have no idea! She is active, eating like a pig, her tummy has gotten a tiny big bigger but nothing drastic. Still no mammary development.
We have thought that we felt movement, like a little foot kicking the side of her tummy. I do still feel this but I don't know if it is just that we thought there were babies and so assumed it was babies? Kind of wishful thinking?
I will let you know what happens.
