Pregnancy glow, my way

All the books tell me to expect bad skin during pregnancy. Outbreaks and grease and stuff. But I (apparently) decided to go a different way. My skin hasn't been this clear since... well, forever, and there is no grease to be found anywhere. My hair, which usually has to be washed every other day at least or else it turns into dangling bits of grease, doesn't produce grease at all any more. I find myself trying to remember when I last washed it - was it three days ago, four perhaps? Makes no difference, because it doesn't get dirty. Lack of grease is my version of that famous pregnancy glow, I suppose.
