If your snake is still eating she in most likely not gravid. I did not want to accept this fact with my first breeding earlier this year either. One of my girls was giving me all the signs you listed. I continued to feed, until one day she refused. Three weeks later she ovulated. If you girl is eating agressively she is probably still building follicles. I would continue to feed if I were you. You might be experiencing a pre ovulation shed. Just be patient, it pays.:gj:
