I was asked me how my "pregnant" ball python was doing..

In a previous thread I posted about my male ball python having some poo-issues, I was asked how my "pregnant" female was doing, I had mentioned that she kind of went stagnant for awhile, and didn't continue to show any other signs of being pregnant.
Oddly enough, today she has been on her back, and now she's nesting in her egg box.

I have all of the supplies for her incubator and what not, I just hope she ends up laying the eggs.

Before, I figured she wasn't going to lay eggs, I may've been given some wrong information at my local pet store... I am not sure the time span all of this is supposed to happen in. Can someone tell me step by step what symptoms should occur, for how long, in what order, and how long between each one?
The way it was explained to me at the pet store was that all of this was supposed to occur in about a month. Color changing, belly rolling, seeking out the coolest region of the tank, pre-lay shed, then boom. Week later, babies.

Any help would be appreciated.:gj:

Did you ever see a glow or ovulation? Does she look like she has eggs? Maybe if you posted a pic of her that would help

She totally had "the glow", she is usually a dark greenish brown, and she nearly turned brighter than my jungle pastel. She has been digging up the moss in her egg box, and she did some belly rolling in her hide last night.

This is a photo of her before her glow. (She's the darker one)
Then the second photo is when she FIRST got her glow.

I was shocked, she nearly looks like a different snake.

Any ideas would be appreciated.
