Hi. I've just had my scan at 10 weeks and 5 days and also my blood test for Harmony. The results should be back next week however the scan showed a thicker than normal fluid build up at the back of the neck. The Sonographer didn't give me a reading as the foetus was 41.9mm and it needs to be 45mm before they measure it. I don't think I have ever felt so stressed. This is an IVF baby and the thought of it having DS just breaks my heart. Does anyone have any advice or has anyone been through anything similar?
