Ok, this is my 5th pregnancy ( have three children, one mc) and I have an nt scan scheduled into weeks. I'll be 12 weeks. I have never had an nt scan done before. I understand why they do it, I just don't understand why this is my first one? Is it my age? I'm 32? Or is it just something new they are doing now days ? If you had one in the pat were they able to give you a clue about gender??
