Veiled Cham still hasn't laid eggs :(

[NiniMarie]

I'm a fairly new Cham owner and recently learned mine might be ready to lay eggs soon. She was spending most of her time on the bottom of the cage and scratching at the glass. I finally moved her into a big cage with a laying bin and covered her cage for privacy. It's been about 4 days now and she hasn't laid any eggs. I want to make sure she is ok and not "egg bound". I tried feeling her abdomen today but didn't really feel anything other than what seemed like her ribs.

Here are some pics I took of her today.

I can't post multiple pics at once. Here is another.

She's chubby but I don't know if she really is pregnant or not
