She looks normal to me. When your snake is white or has very light coloration, it's pretty common to see some pinkish color showing through from their
blood circulation...I believe that may be what you're seeing. As snakes grow larger, the visible pinkness gradually disappears: I can remember many years
back getting my first albino snake, a California king snake hatchling. No thicker than a pen, her scales/skin was fairly translucent and she was quite pink
until she grew much larger...but eventually she appeared as white with yellow markings. Of course, if your snake is heading into another shed, that may
also make her ventral scales appear a little pinkish too.
