No this is not normal and I would be concerned.
Most likely you are not providing her a suitable place to lay them so she is attempting to retain them until she can find a suitable place to make a nest.
You are going to need to put a container of moist soil or sand in her enclosure. The bigger the better. The soil/sand should be warm (85) if possible and should be wet enough for her to dig a tunnel without it collapsing but not so wet that water comes out of it when you squeeze it. It should be packed lightly again so it won't collapse but not so tight that is would be difficult for her to dig into.
Hopefully she will dig a nest and deposit all the eggs and then refill the nest. It is best not to disturb her during any of this process. I don't even look at mine.
Also females need a lot of water prior to and after they lay eggs. Offer water with an eyedropper twice a day by dripping it on her nose until she stops licking it.
