If you did not see her ovulate, then you should keep pairing her up with the male. If she already ovulated, then she will not lock with the male. This is a good sign that she is already gravid. You can offer her small meals, but I doubt that she will take them. It is also a good sign that a female is gravid if she is not eating. After her shed, keep a close eye on her. She should drop approximately 30 days after her pre-lay shed.
Good luck.
