NT 3.5mm scared

I am pregnant with a much longed for baby, after a terrible year. NC as I'm so scared.

Last year I fell pregnant with our DC3 after several years trying. Devastatingly, he was diagnosed with a chromosomal disorder and we had to say goodbye after a poor prognosis following lots of tests, scans etc. I then had an early miscarriage at the end of the year.

This pregnancy, I have had the Harmony test and that came back as very low risk (1:10000) for all the major choromosomal issues. We had a week of joy, after an anxious start, only to find out at the 12 week dating scan that the NT looked very high and when it was measured was 3.5mm. We are meeting the consultant later to discuss possible issues, I spoke to him briefly by phone and he thinks a chromosome issue is unlikely (after my son being so poorly though I am worried, it feels we are doomed) but mentioned a possible heart problem or an infection.

I don't have anyone to talk to in real life except DH and looking for a hand hold, I suppose. Has anyone else had a high NT?

I'm 38 (39 soon) and it feels our chance has slipped away.

I haven't had this, but wanted to send you best wishes. You must be so worried. I just know what is meant to be will be.

Bumping for you X

So sorry you're going through this. 3.5mm is the cut-off for low risk but its v.low for high-risk (if that makes sense) you know some chromosome disorders are not present from NIPT so thats a good sign. I know there are others but its also a high chance your baby is fine. Our NT was 4.0mm and we also had a clear NIPT. Had more scans to check and confirm low risk. Are you being offered more scans or tests?
Thinking of you flowers

Heebe thank you for your kind wishes, seems antenatal tests is a quiet topic.

User I'm sorry to hear you've been through this but glad to hear you had low risk confirmed. I saw the consultant yesterday and I'm having a fatal echo in a couple of weeks and the consultant is doing the detailed scan at 19 weeks. If there are indicators of a chromosome issue at either of those then we will go down the amnio route and possible micro array testing. I've also had a blood sample taken to rule out parvovirus. It's the not knowing and waiting that's awful.

I have just been through the same thing with an NT measurement of 3.9mm, see this thread: www.mumsnet.com/Talk/antenatal_tests_choices/2860945-1-in-28-DS-risk-next-steps

After we had the high NT measurement I had the Harmony test which came back low risk & reassured me but then had to wait another 3 weeks for the fetal echo and anomaly (20wk) scan and it was a horrible wait. Thankfully for us there was nothing of concern from the fetal echo or anomaly scan so we decided not to do an amniocentesis. They measure the nuchal fold rather than the NT at the anomaly scan and this measurement was not of concern which was reassuring.

Good luck for the scans & hope the wait goes as quickly as possible. Xx

sunshine thank you so much for the good wishes and linking your thread, there are some reassuring replies. I'm so glad you got good news. I hope the rest of your pregnancy is uneventful and that you can enjoy it now x

Just to add some reassurance - I recently said a very said goodbye to dc3 after NIPT showed t21. When I went for the cvs the consultant said she was leading the IONA (NIPT) liaison team for the hospital and she had never known it to be wrong. As the consultant says a high NT can indicate a heart issue but more likely just that it was hard to get a truly accurate reading.

I think all will be well and wish you all the best

Gurraun I'm sorry you have also had tfmr, it's devastating, I hope you are getting rest and support. Thank you for the reassurance re NIPT, my mind keeps going to dark places worrying that it is a rare chromosome disorder, having been to hell and back last year it feels unbelievable we are in a scary situation yet again. Are you in contact with arc? I found the forums a huge help. Take care.

Thank you. It is an awful experience- I was steered to ARC from here and they were helpful. Sadly DH won't consider trying again as he feels it was too awful an experience to risk repeating and we already have 2 lovely boys. I'm trying to come to terms with that and move forwards but it's hard.

Good luck - I'm sure it will be ok, NIPT is such a reliable test, however I'm afraid that having had such an awful experience you won't enjoy this pregnancy until you have a lovely healthy baby in your arms.
