In or Out?

The other day I noticed that my belly button (an innie) was not looking quite as 'in' as it has in the past. Steve noticed too and it was even somewhat noticable from the shirt I was wearing. So if/when it pops out, will it go back? That's weird. I didn't really love the comparision to a turkey Steve made and doubt that my navel will determine when the baby is really to come out, I guess it's just one more way that the body changes during this process.
