There's been quite a few anecdotes over the years of some females preferring to soak in rather than wrap around the water bowl prior to an Ovy. Here's to hoping yours is on the right track!
Here's even a thread about it from a while back here:

The only other thing I would keep in mind is to be mindful of her humidity. Yes, some of the bedding is already damp from her having pushed all the water out of the bowl, but I see what looks like a bits of shed skin in the bedding as well? If she's not feeling like it's humid enough, she could just be preparing for a shed and not an ovulation.
