How soon after the Obagi Radiance skin peel can I return to the Obagi Nu Derm regime?

I had an obagi blue radiance peel yesterday, and today my face is brighter except for all my pigmentation areas which have severely darkened. I also have new patches of pigmentation. Help, what do I do? I have African American skin and I'm fairly light, but the pigment is extremely dark. Should I wait a few days and go back to using OBAGI nu derm (with tretenoin), or start using it immediately? I don't understand how it happened, as I had been prepping my face with the system 10 weeks beforehand.
