I too ma going team green! I have my 12 week scan in exactly 1 week!! My dp does not know about the nub theory, I want to know what we are having but dont want to know! I want to do the old wives tales and the obsessing over nub and skull but dont want it actually confirmed by the doctor. If it is a girl i really would like to knowbut not let dp know as he really really wants a girl so i could only imagine what he would be like if i gave birth to a baby girl, he would cry, so it would be great knowing to be excited for him in that way, but for me i am still not really bothered what gender it is which really has surprised me!
