Don't worry. The pinkish belly is an early sign of a shedding! That's how I know mine are going to be shedding soon. I'd leave her alone for a week or two, as far as handling goes. My snakes often display a pink belly first, then the foggy eye-caps come a few days later. Sometimes the eyes look clearer, after they've become foggy but before the snake has shed. At least in my experience.
I ALWAYS have whole sheds on my snakes.
