Doesn't sound very promising. She may have quite a bit of material in the abdomen if she's never laid an egg.
Can you feel an egg if you feel inside the Vent?
Is Vet Care An Option?
Please get some photos!
The vent, her poop, her, the blood, the yellow material....photos please.
You are feeling eggs in the "belly". Where? Is this below the vent between her legs?
If the "eggs" you are feeling are in the abdomen, you will not be able to get them...
