My vet only does ultrasounds too. I am taking her to a different vet that does them. My cousin just finished her pediatric small animal training at UPenn and her professor highly recommends the Xrays to determine the skull size, the number, and the positioning of the pups. I have heard that day 55 - 57 is appropriate for X-rays.
