Puppy has Parvo: when will we be out of the woods...

Hi, I recently adopted a miniture Dachsund. Since we got her she has been diagnosed with cocidiosis and Parvo. Were on our 3rd day of parvo treatement and our 5th day of cocidiosis treatment. We opted to treat her at home because the vet said it would be $2500 to treat her at the 24hour hospital. Currently were giving her 50ml of IV every 8-12 hours, an anti nosia shot every 8-12 hours, and an antibiotic and some medicine for the cocidiosis once a day. She has yet to have a bloody stool and is willing to eat only to throw it up. She was about house trained when she was diagnosed with parvo and since the diagnosis insistes on going outside to have diahreah/throwups. She is very lethargic but seems to be fighting the infection pretty well. I have believed sinec she was diagnosed that we could get through this and she has maintained her mood/activity level throughout. What are some good signs that we are almost through the woods? Anyone who has faced this first hand successfully please respond and let me know what i should be looking for.
