English bulldog pup died vet negligence.i was trying to be such a responsible owner beond normal..?

how would you feel,i a.i my bulldog went to the vet 4 weeks later and i was told no pup,i either thought i was crazy or false preg.2 weeks later i had them check again with ultra sound still they said no pup.1 week and half before delivery i insisted they feel and check her x-ray i new a pup was in there i could feel it and the vet could not feel nothing.of course the vet seen the x ray and said yes one pup..we did two ex-rays because iwanted to do a c-section the vet said the pelvis looks good for normal delivery so i took there advise...my dog never went in to full labor because she never had enough hormone which the vet told me after the fact because there was only one pup...i called them 3 times the first sign of labor and they said if dog is not disstressed dont come in so i never did...i even called another emergancy vet in the middle of the night and they never shown any concern either.so i told the vet im comming in so i went that morning and the pup was dead in the birth canel
