Like Mike said, you should be able to see the eggs in her stomach if she is pregnant, especially since she is light colored. My friend had a similar situation, he bought a pregnant female from the local reptile shop. They said "she would lay any day now." He waited weeks and nothing, then out of seemingly nowhere she laid.

I think the stress of moving into a new place may delay laying times. I've never had a gecko lay an a clutch so this is just speculation. I'd just give her some more time. She looks very swollen, so my guess is yes, she's preggo.

Good luck, and keep us updated!
