Make sure you have a good laybox for her- she looks like a sweety. Judging by the pics you still have a while before she's ready to lay. In my experience (never bred geckos, but I have one that likes to develop infertile eggs) they get VERY obvious bulging lumps in the gecko. Have the eggs dropped yet? They develop a little higher up, and then drop down closer to the vent when she's getting ready to lay.
