Had my scan yesterday and was really throwing as baby had its back to me and could not see a clearly recognisable nub, certainly nothing that looked like a girl. All that I did see was lots of lines all over the place and perhaps a stacked nub. How much does the correct position matter, or should I trust my insist which say 80 percent boy?? Have been in tears since the scan when I should be phoning everyone telling them the news!!
