Ok, I am fully aware that supposedly before 12-13 weeks nubs can change, with most times a girlie nub turning boy. Those of you who have seen/guessed on lots of nubs typically how common is it? I see some nubs in the 11 week (usually toward the end of 11 weeks) that are already very obviously boy or seem to be going that way but just wondering how often a nub around the end of 11 weeks/beginning of 12 that is girlie does turn into a boy. Is it that half the boy nubs have started to rise by then or is it higher like 75% already starting to look boyish? Just wondering as I have a girlie nub at 11 weeks 6 days and am really hoping for a boy but just want honest opinions on my odds that this nub will start rising?
