Dude I am not trying to bash you but this was a bad move/risk on your part. She "WAS" in good health when you got her so it is either 1: pre-existing Or 2: you did something wrong, either way there is a good chance you are going to have more problems.
Consider all 70 in QT now. FYI I could care less if you have 1 or 1000, neither impress me because you still took a gamble on a way to short QT. I have a couple really close friends that I trade with and they still get a 90 day QT. I have too much investment to roll the dice on.
Put your temps up to 95 and get her to your vet asap.
BTW she was fine 30 days ago too.
