How many days between shed and laying eggs?

Just curious, my very first female that I think is full of eggs is getting ready to shed, she is turning blue! I know there's a certain number of day after shed that they are supposed to lay. What is the average number of days and how many days before I find out that she isn't going to lay?

This may help.

30 days on average.

Awesome! So it looks like I'm may be able to breed her in November again since it's early March and she should lay in early April. That would give her seven months to fatten up.
