I had a private gender scan done the other day (13 weeks) and the sonographer asked me if I had the NT scan yet? And I said no and left it at that as I was so excited over the fact I'm having a boy. It wasn't until I was in the car home my husbands like "why did he ask about your NT scan?" And that's when I started to worry like why would he bring it up? Did they see something wrong? My midwife told me I didn't need to do the NT scan as I'm extremely low risk but now I'm worried? What should I do?
