If it were me, I would go and get an xray done. Most times the vets are really good about the small animals and will give ya a two fer. IE you will get two views on the same xray film, from diff angles for the price of one. I know that you know she has eggs, but the xray will show how they are positioned. I'm sure you know already but before oviposition the eggs kinda form up into lines or stacks. Atleast you would know if she is not ready yet.
If it helps at all the previous link I put up has xrays on it of a gravid panther over the course of a month. The last few xrays, show them lining up, and ready to be laid. The previous are all jumbled. I can try and make them clearer/brighter for you too if that would help pm me.
