From that picture I don't see anything unusual going on. Is she still eating? Will she still lock with the male? If you answered yes to either of these then she isn't gravid yet. If the answer to both of these questions is no, then just keep offering her food and keep an eye on her.

A gravid snake is hard to miss. The body is very "peaked". The spine sticks up while the lower sides stick out. If she's bowl wrapping, she is probably still building and should be eating and locking still.
