Nah I think you're fine. I have 1 bp who ninja sheds and goes from dull to blue to completely shed in less than a week. Then I have another who takes freaking 2.5 weeks to go through the whole cycle. Every snake's different.
Mine are the same way. My albino went blue 13 days ago and as of last night she still hadn't shed. My pastel went blue this past Friday and shed out yesterday.
