Do your bones crack when you stretch?

I have osteoarthritis, but I do go walking everyday. I notice in the mornings that my bones tend to crack when I stretch, too. Is that a normal process of aging? They didn't use to, but I suppose I need more calcium or over the counter vitamins or something. Do your bones crack when you stretch in the morning?
