I CHANGED USERNAME AND FORGOT TO CHANGE BACK
Hi all haven't posted for ages but I have been lurking a lot. Good to hear so many positive birth and scan stories.
I've had a bit of a rollercoaster of emotions these last 2 weeks but I think most of it is caused by me worrying and googling to much.
I am now 21+1 and have a big bump now. To recap my story my NT measurement was 2.7/2.8mm not great but not terrible. The risk of T21 was 1:480 (NHS) and 1:1315 (FMC). Decided not to risk the CVS.
Had a scan at 16 weeks and all was fine. Had 20 week scan and all was ok apart from the amniotic fluid level which was right at the top of the normal range. High amniotic levels can sometimes be an indicator of structural/chromosonal problems. We weren't too worried because it was still just in the normal range and I had exactly the same issue with DS2 and he was fine.
However when I got home I looked at the baby's measurements and the Abdominal circumference was on the 95th centile but the femur measurement was on the 3rd centile!!! (I'm not short at 5'7")
Phoned the doctor who had done the scan and she didn't seem too worried about it and said they get measurements like that all the time and it is usually nothing. I knew short femurs can be a marker for downs, she said it is a minor soft marker when pressed the other thing she mentioned was Skeletal Dysplasia of which there are many types one of the milder types is dwarfism.
Spent the rest of the week getting into a right state, crying, getting really depressed. I could put to the back of my mind one problem but the combination of the highish nuchal, the fluid and the femur length was enough to convince me there was a problem. Found myself detaching from the baby.
I came close to booking an amnio, though DH was not keen, but thought I would first go back to the FMC for another anomoly scan. They were great there and said that the fluid level was normal and the femur bone seems to have grown (or measured more accurately) quite a lot in a week from 29.2mm to 33.3mm, which puts it in about the 33rd centile, a lot better, normal range they said. The Abdominal measure was also closer to average about 66th centile.
But.. they did pick up someting new 2 choroid plexus cysts in the brain which are harmless in themselves but can be a marker for Edwards or Pataus. However the doctor said that for these syndromes they would in 99% of cases pick up other problems on the scan, and everything else was fine. So I am not going to worry about this, its not something I would risk the amnio for. So as a result of this my risk of Downs was halved and the risk of Edwards/Pataus remains the same, can't remember the figures 1:900 and 1:2000 I think.
I am going back to NHs hospital next Tues to check on the fluid levels and back to the FMC the following week to see Prof Nicolaides.
Even though they picked up the cysts I am not worrying too much and my feelings of detachment have gone, am feeling postive again about this pregnancy.
Sorry for the long self indugent post, needed to write it all down
