I have read about the nub theory and am just curious to see if it works. This scan was taken at 12 weeks 2 days and I am now 13 weeks. We find out the gender in a months time.
So just for fun, what do you predict? I have read that the nub theory goes along the lines of... if the nub it less than 30 degrees in relation to the spine it it more likely to be a girl and if the nub is more than 30 degrees to the spine it is more likely to be a boy. All boy and girl nubs are the same length at 12 weeks apparently..
