Thanks everyone for your prompt response. I think we will leave everything as it is and wait till the 20 weeks u/s. DH seems quite calm about the numbers and seem to think everything will be ok. And if we do find out otherwise at the 20 week scan we wouldn't do anything differently anyway. I guess the only difference is if we know, we can better prepare ourselves.
I felt a little lost after the scan because other than the numbers talking and that it is entirely up to me if I want an amnio, no other option given eg. 16 u/s or genetic counsellor etc...
So that I can be better prepared for the next scan, what do they do at the 20week scan? What information should I get.What do I need to ask?
Any recommendations of sonographers that you felt gave you information to help understand your scan? - please pm me
TBH if there is something wrong, they won't really be able to tell. The measurements they take and the particular aspects they look at, the thickness of the neck etc, isn't the same at the 20 weeks, that is why they do the measurements at 13 weeks.
The 20week scan is a morphology scan - so looks at things like making sure the abdominal wall has closed, the organs are insinde the body, the legs and arms are the "right" length and the organs are where they should be and functioning...they also check the spine is gorwn properly (looking for signs of spina bifida)... so basically it is to check that everything is where it should be, attached how it should be and functioning as it should be.
They will look at your placenta and make sure it has 3 vessels and is functioning correctly, and also at your ovaries.
The sonographers are usually very well trained and can explain to you what they are looking for, and why they are looking at everything. They cannot however give you a diagnosis of anything, it is not their job to interpret the scans, just to take them, but they are very helpful in helping you understand what they are doing, why they are doing it, what exactly they want to see.
