Hi HaydensMummy - I understand how scared you are as my DH and I went through this last year. My babies Nuchal fold was 3.3 and I was 25 at the time. This was picked up at 9 weeks in my Ob's rooms - it wasn't even the nuchal scan at 12 weeks. They never did the bloods as said it was very obvious something was wrong. I had this confirmed at a specialist ultrasound place with another doctor. We had CVS done at 11.5 weeks as I just couldn't stand "not knowing" and could not wait till 16 weeks for an amnio as they thought it was trisomy 13 or 18. It was all incredibly scary and we saw a geneticist and genetic counsellor. We were told that if the fluid resolved by our 20 week morphology scan and if the CVS came back clear of chromosonal abnormalities there was a great chance our baby would be fine. By 14 weeks the fluid had started to resolve and by 19 weeks the fluid had completely resolved. The CVS was clear (got fast results back in 2 days after CVS and the rest of results clear bout 2 weeks after). We still were monitored VERY closely with fortnightly scans and cardiac scans as sometimes it can mean heart abnormalities but Our daughter was born happy and heathy last September.
I know how terrified you must be right now. I found my whole pregnancy emotionally draining and stressful but my obstetrician was incredibly supportive and helped by seeing me whenever I was worried or scared for a quick scan.

Since we went through this with my DD last year I have heard so many similar stories of bubs who had high NF but they were born fine, even another girl in my mothers group and her NF was 6.6!!!! I wish you all the best and know that you are not alone and BB will support you on this journey. I hope you get some more info very soon so you can decide what you will do next eg - wait and see, cvs, amnio, extra scans etc.

Huge hugs xox
Thank you so much. it is good to hear stories where the outcome has been fine. Can I please ask about the CVS in case. If our risk is high we would need to get onto that straight away. They say you can risk miscarriage how long after do you have to be careful of that. Do you need extra time off work etc, what is the procedure, risks etc.
