hey guys im new to the forums so excuse me for being a noob
so i got a female ball python yesterday, shes pretty big, probably almost a year old. I noticed that she opens her mouth alot, and she yawns a lot too, is that a bad thing? she also makes some weird noises with her mouth. I was thinking maybe its a pre-shed thing, since her eyes are getting pretty cloudy. what do you guys think?

here are some pics(sorry im not a great photographer)
open mouth/cloudy eyes:


pink belly maybe?
