Once they go into shed, I have only rarely had them lay on their own, although it has happened. I usually start removing, or aspirating, the most distal egg within a week or 10 days of the last ones that were laid. I wait a day or so after each egg to see if the rest will move down to the cloaca on their own. If you wait too long, the eggs will become hard and then your only option may be surgery.
However, if the egg is close enough to the cloaca, you may be able to coax it out with a lubricated snake probe and tweezers. I have never found a fertile egg in an eggbound female in all of the cases in which I was able to extract a whole egg. So don't worry about the eggs.
I cover the whole subject pretty thoroughly in my book. It is too long and involved for a post though. You may not feel comfortable doing the procedure(s) yourself, so you may have to find a vet or at least an experienced keeper to help you the first time.
