Hard to tell from those pics, she's got that gravid look, does she spend most of her time on the hot spot?
In order to properly diagnose where she is at, we need all details.
How long have you been breeding her, as in, could this be a very late 2009 clutch? Females can produce year round, could be that you cycled her late and she's finaly getting it done for you now!
Females will give a lot of signs of where they are at in the follicular building stages.
Here are some of them;
- Contorsioned spine (lumping)
- Wrapped around her water bowl
- Neck in water bowl
- They glow (get much lighter in color)
- Lying upside down (like your pic)
Take a look at this breeding page link, good examples of follicular development pics.
