Hello - I am 11w5 and have a nuchal scan and harmony test at the fetal medical centre later today. I have one son, and have had these tests on the NHS before but was more worried about miscarriage (had 3 previously) and didn't give any thought to the outcome of the nuchal/harmony etc. 
But I am now 41 and convinced that the tests will show something. And I've been giving myself a hard time saying it'll be my own fault for leaving it so late.
My question is what should I expect from the scan tomorrow? How quickly do they give you the nuchal measurement, do you get the combined result on the day, how quickly will the harmony result come back?
Thanks in advance :)
