Hi Jessy i replied to you thread in second trimester.
What is the Quad scan ?

Please email in you need to talk my chances of a Downs baby was 1:294 and i had the amnio done last week and waiting for my results.

ETA: With them looking at the heart development at 20wks it doesn't always mean you will have a baby with downs if they find a problem with the heart as a baby without downs can hane heart problems. I was going to wait till my 20wks scan to see what was going on and if we can tell from the scan if something was wrong and after talking to a genetic counsellor she said they can't always tell as some markers they find could still not mean the baby will have downs. The only way to know for sure is to have the amnio done. Even if you get bad results and keep the baby at least it can prepare you for the future with your child.
