I'm 20 weeks pregnant with DC2.
Our DC1 was found to have elevated nuchal translucency at 12 weeks, so we would through various tests including amnio and fetal echocardiography. All came back clear although after birth she was diagnosed with congenital defects. She is absolutely wonderful, healthy, bright and active and although she will need major surgeries in the future touch wood we hope it will not affect her too much.
We paid for the Harmony at 10 weeks with her but it was a waste really (we never expected the 12 week scan would show problems so were doing it as a just in case sort of thing) as when problems were flagged we later went to amnio anyway. Even though her Harmony was low risk it was suggested we rule out other chromosome problems via microarray.
Thankfully DC2 had a normal nuchal translucency at 12 weeks, and with bloods were given a very low risk of the three trisomies on combined test. I thought we may as well save the money on Harmony this time since I know now there are so many other things the baby could be born with that it doesn't show anyway and although we can afford it from savings, the money might be better spent on preparing for DD's treatment (although we are at an excellent children's hospital on the NHS, we do pay privately for some stuff if we need to in order to facilitate best care for her - ie we paid for a heart scan privately ahead of her NHS MRI as it was necessary but the waiting list for her heart scan on NHS was months and months longer than the waiting list for MRI - also paid for physio privately for same reason etc)
The anomaly scan recently was normal and no obvious problems seen although the sonographer did seem to spend a very long time on certain things, which I knew was completely normal as a medical exam but did seem particularly so. It might be because we were scanned by consultants with DD and they seemed to zip through it while still being eagle eyed if that makes sense!
All measurements in normal range although one near the 10th centile which I remembered from before it possibly maybe a soft marker for T21 (but a very soft one if anything) and sonographer did not raise any concerns or need for further investigation.
It seems though like everyone I know or read about on here has Harmony as matter of course (I know mumsnet has a large number of higher income families, and if we had as much disposable as before I'd probably have booked it from the outset, just being more cautious now) and now I'm wondering if we should have it just for reassurance. I'm not sure we'd interrupt things if it did suggest something, but would rather know. I know it's bit diagnostic but consider it highly accurate for T21.
I suppose I just have this fear now of a diagnosis of something at birth and can't accept that things may be entirely normal.
DH thinks there's nothing to worry about but says we can book it if I want to.
Should I save the money or book it quickly for reassurance, and if I do will I simply worry about something else instead? (Probably)
