bleeding syrian hamster

[chamaya]

my Syrian hamster(Jasmine) is 1 year and 10 months old. She is the sweetest little thing you would ever meet and has never once gotten sick. Today, out of the blue she started bleeding from her vaginal opening. we immediately took her to the vet because we were so shocked as she showed no symptoms of being sick or acting lethargic. We were told that it is likely to a tumor in one of the reproductive parts in her body but that was just a speculation. we were given antibiotics and sent home. She is getting an x-ray on Wednesday to see what's really up. do you guys have any ideas of anything else it could be that's making her bleed and foods that can help heal her or clot the bleeding since she is still bleeding quite a bit? also, should we be worried about dehydration since she is bleeding( btw she's eating, drinking water, peeing, and pooping well)
thanks for any tips!
