OK, my ball python, Lilly, is I'm guessing 7 months old, I got her at the end of January from Petsmart (where I work)
She had shed two weeks BEFORE I got her, I've had her home for almost two months and she has not shed yet and it really worries me.

She eats fine (frozen Fuzzies)
Humidity stays around 40-80
I've soaked her in warm water

I have noticed her rubbing her face against her hides but that's it, no discoloration or cloudy eyes
