Has she ever laid eggs before? Her abdomen looks pretty large in comparison with the rest of her and with her hips and tail which seem a bit thin (or maybe just the angle of the pics?). This could be a result of egg binding. In the third and fourth photos you can see bulges that may be eggs, however these are rather far up on her abdomen. If she was close to being ready to lay eggs, they would be lower down in her abdomen, sitting low in her pelvis just above her legs. In the third photo it does not look like there is an egg in this position on her right side (can't really tell about the other side from the photo). Usually the eggs don't bulge out of the sides quite like that unless there are more eggs bound inside that are pushing the other eggs out to the sides.

Can you palpate her abdomen? You should be able to gently do so and you should be able to feel individual eggs if they are there. There should only be two, but if she is egg bound you will feel more and they may be dispersed all throughout her abdomen and sides.

Is she eating and defecating normally? How do her calcium sacs look?
