We have had a scan every week and this past week, at 13+6, she told us it was A girl. Isn't it too early to tell for sure? She had to look really hard And could eventually point out three little lines, which I know means girl, but shouldn't there still be a nub that early? Here are nub pics at 11+5, 12+5, and then a potty shot at @13+6. The 11+5 to 12+5 really looks like boy progress!
