Not that it has, but I'm really close to having an outie belly button. I'm still doing good with stretch marks, that is I don't have any yet. I do, however, know where I'm going to get them, as I have 4 red dots on the outside of each hip and 1 red dot at the corner of my appendectomy scar. So, I figure in the next 6 weeks I'll get to see some stretch marks. Oh Joy.
