Help! Mites

Sorry for not updating earlier! Been having a busy couple of days. I checked on her twice today, she hasn't gotten any of her shed off & it's still crumpled up around her face. I sprayed the enclosure again today just in case, my house is really dry so I figured it would help a bit? I've never really had a shed like this with my bp, not sure how exactly to go about fixing it.
She also pooped today, I think twice? The first time I checked on her I saw she had pooped & I replaced the paper towels, & the second time I saw a smaller brown spot on the towel, it looked the same as the first time but they were both really liquidy? They looked like when she urinates but brown, nothing solid. Is that normal? I'm not sure what to think, I'm trying not to get too worried but I don't know what this would be caused by Any input would be really greatly appreciated!

Well, she's just eating pinkies, right? if so, that stool is fairly normal...pinkies aren't much nutrition or fiber.
Can you post a pic of her shed issue? (you could just spray her, y'know...desert snakes in the wild actually come out when it rains to get a drink) Did she shed her body?
What exactly is her size (length) now?
