Just to update...
Having wound myself up into a panic that she might be eggbound, I was all prepared to take her to the vet.
However, I thought i'd better actually check her underbelly to make sure there is still an egg in there. I had not handled her up until now, just in case she was about to lay and I stressed her out through handling.
Anyway, I picked her up and her underside looks like this:
All pink, I can't see any white patches where the egg would be. Does this mean that there are no eggs in her? I know that the eggs are pretty easy to see through the skin when they're in there, so I can't see how it could still be there.
This is a photo of her about 5 or 6 weeks ago, when I first noticed the white developing:
Can Gonis reabsorb eggs? I've found no information regarding this with cave geckos specifically, though have heard that Eublepharis can.
The female seems pretty active, and I saw the male and female mating this evening.
Any input or experiences would be gratefully received.
