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

Thanks again
