How long ago was it when she was spayed? If it was very recent, is she on pain meds? If not then I would recommend discussing this with your veterinarian and see if they can put her on some type of pain medication. If it wasn't within the last week then it most likely has nothing to do with pain related to the spay and there may be something more going on which would require a vet visit and potentially a trainer.
