Mantis molting?

[IIIIIIIIIIII]

So I have this ghost mantis yeah. I've had her for about 2 months and her last molt was 1 month ago. She is showing symptoms of molting such as ignoring food and staying high up on a branch, however, she hasn't eaten in almost 2 weeks and haven't molted either. How long should I wait? Getting a bit worried.

That does seem like a long time for a moult.
