Not 100% sure this will answer your question but, if she was bred and laid a clutch, you can in theory breed her again two weeks after to ensure her next clutch will be at a high fertility rate which she will most likely lay 4-5 weeks after that 2 week period. That is if she will allow it to happen. But, that is not required as she will most likely retain sperm from the first time she was bred and can lay a retained clutch with a good fertility rate as well.
However, if she was not bred and just laid an infertile clutch, I would give her more time to recover after that clutch before you breed her. She might not lay another infertile clutch for a few months so the two week period isn't really necessary.
