I wouldn't worry too much about her not eating yet. My normal girl eats when she wants, she just had a 3 week strike. I wouldn't over think it.
As for staying on the cool side.. I would first check your again, what are you using to get your temps? How is your enclosure heated? Is there a thermostat on the heat source?
If that's all Ok I would say she just wants to be cooler... maybe the time of year...
