Ovulation, pre lay shed and lay questions

Ok, my first girl is going though what I believe to be ovulation today. She looks huge and her tail is sunken. If I am correct I am assuming shed in three weeks and then 30 days for egg lay? Is that about right?

How do I post pics? I can't seem to get them to post anymore. Anyone know of a host I can use? I will post a pic of her fat self.

shed in 2 weeks, egg in 45 days after ovy on average.
