It looks very promising. I cannot say if she has ovulated yet, but a good shot of her laying on her belly, with her spine pointing up would be better at trying to make that determination. It is very rare that you cannot see a gravid female from her look. Her spine will be very pointy, and she will be very swollen on the lower half of her body where she is carrying the eggs. Once you see this once, you won't forget the look.

I hope that helps some.
