Thats fine most are gravid for about 2 weeks maybe even three. She's probably just hanging out in the hide. And egg binding is mostly treatable by surgery, but for a second I was just worried if had been over 3 weeks. She's fine!
I can't say for sure, but I would only be worried if she doesn't lay after she has been gravid for three weeks. Any way you could take a picture of the way she sits?
