Not spaying my doberman (Von Willebrand Disease)

Hi everyone. Wanted to ask for an opinion on spaying my doberman. I recently went to the vet as I rescued my dobie and wanted to get a blood test to work towards getting her spayed. I ended up getting the results back and the vet told me she had a really high percentage of Von Willebrand disease and that it would be super dangerous to get her spayed because of how badly her blood doesn’t clot. Then told me he would not do the spay and if i wanted the risk i would have to take her to a hospital were they could do an emergency blood transfer if something went wrong and that it would be very expensive to do so. I’m not sure what to do. I’m very nervous about her getting pyometra as she gets older but just feel stuck on what to do about this. Would love opinions/advice
