Answer
Hi Charmian

If pups were visible with x-rays, then the pups would be older than 50 days with the addition of 7 days, you would be close to gestation.   

With the leaking of her mucus plug, that also is an indicator that she is getting ready to whelp.   

Small dogs are the same as big dogs.  The dam will clean and eat the sacs and the need a whelping box or quiet and safe area to whelp.

You didn't mention what breed she was and as you don't know what she was bred with, I would keep your vets number close at hand in case complications arise and a c-section required.

Good luck
