I am starting to wish I had taken a "before" photo of my belly button. Yesterday as we were lounging in bed, Mike mentioned to me that my belly button looked different. I had noticed a slight change the day before. It is a little less deep than usual, and the shape is slightly different. Makes sense -- as of week 21, the uterus is supposed to be 1/2 an inch above the belly button, which of course must mean more pressure on that spot. It's still not too obvious that I am pregnant when I am clothed, but the belly is definitely starting to get bigger. Today I am wearing my first full-fledged maternity outfit (both skirt and shirt, thanks Mom!). It's great because it is more comfortable than tighter clothes, but still not obviously "maternity." Still, clothes won't be able to hide things for much longer!
