Ok I know this is rather silly, but I am worried about down syndrome. I had an NT scan a week ago and did not do the blood tests as I didn't want a statistic, but now I am worried because it is only 60% accurate without the blood. The NT scan was great at 1.1 and there was a nasal bone. I am 31 years old. However when I look at the picture It is hard for me to see the nasal bone and profile looks rather flat. I do not know how to put up a picture but if someone can tell me I will do it........
