Re: no eggs in the x-ray?
I know that we will not x-ray any woman who is pregnant (unless completely neccessary) because of the risk of harming the fetus.
All you can do is wait and see how they turn out.
I wonder if the vet was trained well enough to spot the very thin outlining that the eggs would have left? They could have been hidden by ribs? I also wonder if he did 2 views rather than just one.
Re: no eggs in the x-ray?
Just like baby rats are hard to see b/c there aren't actually HARD bone, the eggs probably weren't seen. Not solid enough to cause a shadowing or whiteness in the radiographs (x-rays). And maybe not enough calcium yet in the eggshells to make them appear white in the pictures. ?
I don't think there'd be enough rays to hurt the eggs, but I'm not a vet. If you can candle and see veining, they're probably okay. You won't know until closer to hatching........but Good Luck!
