I can't say for sure without pics, but you can easily check her for mites the next time you're handling her. Just grab a flashlight and look closely for weird black/dark red moving spots. If you're going to do this, I suggest checking on the vent, near the sides of the belly, and under her chin (especially the gular fold). I also suggest using some white bedding like tissue, paper, or paper towels if you haven't already, just to be able to see mites crawling around if there are any.
