Even though this girl has lain, you can see her eggs, can you also see the sharp triangle thing with her spine? A female in the last stages of preparing to lay will have that sharp triangular spine. Once you see that, you know you have 14 days or less. Usually it's only 7. Or at least it was that way with my 6 females so far. Once the triangle spine appeared, they all laid within two weeks. I am not seeing that with your girl yet.
