4.8mm fluid and 1 in 17 risk of downs at 12 week scan

I’ve been scouring the internet for days looking for success stories that this might be ok but the stories are all from years back so wanted to reach out and see if I can connect with anyone currently on this journey or would love to hear any success stories of good outcomes to give me hope

On Thursday at our 12 week scan we recieved the news our baby had fluid behind the spine of 4.8mm, on furthur blood tests my hcg came back at 2.4 and my pap-a 0.55 and have been booked in for a cvs this week. My doctor has told us to prepare for bad news and gave me a 1 in 17 chance of downs and of course we are petrified. It is our first pregnancy.

On top of this I am still throwing up regularly so just feel physically depleted but now mentally broken from the stress, worry, uncertainty and what ifs.

I know nothing is going to change the out come but I feel so alone and scared right now and thought I’d provide something a bit more current incase there is anyone else going through this.

appreciate any stories of similar situations, connecting with others or just words of advice - thank you xx

Hello, I am so sorry you are going through this - it is such a scary time. We were given a 1:85 chance for T21 and have gone through every emotion!

we were going to have the CVS, but due to placenta location had to wait until we could have an amniocentesis- so had an extra 2 week wait! We are still waiting on the results. I think it happens a fair bit that the CVS cannot be done - so perhaps just be prepared in case that does happen! Before the procedure the consultant scanned me and scanned me again afterwards.

even with 1:17 there is still only a 5.88% chance the pregnancy is effected.

I have found putting a plan in each day has really helped deal with the waiting - such as me and my partner spent one day doing Xmas decorations, we did a food bank shop one day, we went to a garden centre etc.

wishing you all the best and please do keep us posted!

Thank you so much for your reply and I’m sorry you are also going through similar. The midwife did warn me on the phone they may not be able to do it, I can’t even imagine having to wait a few more weeks but I guess you just learn to deal with whatever comes your way,

me and my husband did the same at the weekend and I found making the house all Christmassy helped even though I really didn’t feel like it, I have just found since it’s Monday and I’ve gone back to work, it’s that little bit harder to distract myself!

Keep me updated on your results, keeping everything crossed for you

Yes - I got in a bit of a state when the cvs was cancelled as I didn’t expect it, but I know it was the right decision to wait. The hospital did offer for me to go to Kings College in London to see if they could do it, but I figured as my consultant trained there it would be the same answer!

There are so many posts on forums with people having high screening and then further diagnostics rule out any issues so I also find reading them tries to keep me a little sane!

hopefully when you go for the cvs you can speak to a consultant too as that may help calm the nerves a little!

Sorry you’re going through this. we went through it earlier this year with a 6.6mm nt and even though we didn’t get good news - I read soooo many success stories with nt under 5mm. Even my friend was 4.4mm and she now has a healthy one year old. If u have any questions just let me know xx
