If she is gravid and about to lay eggs you will be able to feel them as she crawls over your hand. Just let her crawl over your pointer finger while putting a little pressure on her back with your thumb. If she has eggs you'll feel them, like pulling a pearl necklace thru your hands.
Also make sure your ambient temps aren't too high. Another reason corns cruise is because they are trying to get away from the heat. Ambient should be around 75 with a basking site around 85.
