Love the name by the way
If you took her to the vet and she examined her it suggests she thinks it is just a urinary infection, thus the antibiotics. If she is peeing normally that is good news.
As antibiotics take a little time to work and you trust your vet's diagnosis, I would leave it for a few days to let them do their stuff. As your dog is older she may have other health issues, so I would take her back to the vet for more tests if she does not improve soon.
Hoping your baby feels better soon. Please let us know how she is doing.
