Just has my 20 week scan and really didn't want to find out if I was having a boy or girl but the doc took sooooooooooo long measuring the thigh bones and looking about in that general area im convinced I saw boy bits!! (have compared them with pics on the web)Feel upset that I have now ruined the surprise . How accurate do you think that is?? Have I just interpreted a bit of umbilical cord etc as boy bits?????? Has anyone else thought they saw boy bits and ended up having a girl??
