Gosh, I'm by NO means an expert, but...it's most important for her to be hydrated, and eat. She needs to stay warm and comfortable. It would be helpful if you could get a pic of her most recent poop...also, I'd begin a log, writing down date/time and what you are noticing. Sometimes the days run together, and the progress is slow, so if you write things down (be specific) that will help with a timeline of events. When you say "straight blood" - do you mean like it's all liquid, no other matter in it? I really do think a picture would help. Can you take a fecal sample in to a local vet for examination? She could be wormy...seems awfully young for that, but I guess you never know.
Oh, as far as too much - have you actually seen her eat and drink? Does her crop feel full?
