High NT? (just had 4.7mm) — pls share your experiences

Hi everyone

It's my first ever post to Mumsnet. Just came back from our ultrasound (12+5) with an NT of 4.7mm. Have to say that sonographer and the screening midwife were both lovely (but crikey, those 'comforting' rooms with pictures of trees and boxes of tissues...). Combined results should be in early next week. I think we'll be likely to ask for a CVS.

I've spent the evening trying to research what this might mean, and there's some relief in statistics from the academic papers around, but somehow hearing personal stories of mums who've gone through this (whatever the outcome) is hugely reassuring—just knowing that people come through it.

I'm 33, with one DS (turning 4 in a couple of weeks). We had a MC before him, and I've always expected the worst with pregnancies as my mum had a terrible time (6 pregnancies, 4 births but one v premature and one with Downs and only made it to 9 months, so now only 2 children alive and well).

I know the next few days are just part of a waiting game, but any stories would be hugely helpful. Also, any advice on how you've talked about this with a toddler? We told our son about the pregnancy early on and he's been so excited about it. He was there at the scan too, and then got a bit confused when we looked a bit sad. I'm feeling hugely grateful for having him in our lives right now. He's one hell of a distraction.

Sorry for the long post!

Hi,

Sorry you're having to go through this.
I don't really have any words of reassurance other than to say we're going through the same right now. Had a reading of 4.2 at 11w5d which was 10 days ago. Expected to have to wait a week or so before getting results from combined but had a call from the maternity unit the next morning with an appointment that day to discuss our choices.
They offered us CVS there and then, or amino in a few weeks, both of which have a small risk of miscarriage but would give initial results within 3-4 days.
They also offered us the non invasive Harmony test privately (£400) which has no risk of miscarriage but which is 2 weeks wait as sample gets sent to California. It's still classed as a screening test as 99% accurate rather than 99.9% of cvs or amino.
We opted for the Harmony test as we've had previous miscarriages and didn't want to take that risk. So in the middle of that wait for results now.
We'll also have a very detailed scan at 19 weeks ( and probably additional scans later) to look for other defects that there seems to be a higher risk of with high NT readings. So it's going to be a long couple of months before we know if everything's ok.
I posted a similar thread to yours last week and had several responses from people who had high readings but everything was fine. It was reassuring to know that in the majority of cass everything is fine! I'm holding onto that and staying away from Google!
