My female was gravid when I bought here. She was about ready to lay again and I placed in a soil/sand mixture for her to lay. Now she does not look gravid. Could anything have happen? I dug through the soil just to check if she laid and found nothing. Her stomach was huge for the last week and half and now it is not. I could feel the pearl like eggs in her stomach so I am not sure what is going on. Is this normal or is something wrong with her? I felt her stomach and I could not find anything. What should I do?
