She should shed very soon. The skin was peeling back a little on her nose. I suppose it could be some skin maybe covering the nostrils I'm not sure.
Very good chance you have nothing to wory about. My male normal BP has a wheeze whenever he sheds that always goes away whenever he sheds out fully. Just keep an eye on it, keep your temps up and enjoy the new snake!
