Hello, I'm 24 weeks pregnant with my first baby (after a miscarriage last year). At my nuchal scan (at Kings in London) at 13 weeks my baby's nose bone wasn't visible, so my Downs figures are 1:130. All other soft markers were normal and so were the bloods; age was a factor as I am 36. I declined a CVS as I knew I wanted to continue the pregnancy although havent ruled out the possibility of a late amnio just to be as prepared as possible.
At my 20 week scan the nose was there (hurrah) but JUST within the range of normal. I understand that my ethnicity may well play a part in a small nose. My downs risk remained at 1:130 but would have been revised to a higher probability of downs had the nose been .2mm smaller.
I was just wondering whether anyone else had had a similar experience of the nasal bone being the only marker, and how things worked out for you? I know a lot of hospitals don't even factor it in, but King's do as they pretty much invented the test. Like I say, it doesn't affect my continuation of the pregnancy but I would find it really helpful to hear other experiences.
