Jeweled Lacerta not eating

We've had Rudania for a little over 2 years now, since she was only a few weeks old. She has been an incredibly consistent and wonderful pet. She eats 6 days a week, she sheds every couple months, she is active and curious but never aggressive. The past 3.5 weeks though have been a different story. She has not eaten although we've offered her a variety of bugs, fruits and veggies. She wants to be out of her enclosure constantly and when she's out, she's always searching and hunting. She aggressively humps one green blanket and one blue pillow in particular, latching onto it with her jaws. She has never exhibited this behavior in the past. Her actions resemble those of a male trying to mate, but we are pretty confident she is female comparing traits at the base of her tail to a guide found online.

Although it's been 3.5 weeks since she's eaten, she is not lethargic, her eyes are bright, she is active and not otherwise behaving in any manner that would indicate she's sick. She drinks water daily. I just have no gauge as to how long this activity will last, or how long it will be before we should expect her to eat. Any insights would be amazingly helpful. Thanks!
