Hi, I had my 12 week scan yesterday and the NT measurement was 8.3 so I have been put at very high risk of the baby having downs syndrome. I am in bits. I am due to have a cvs today, I know it carries a risk but I feel I need to know if the baby has downs so we can prepare. I have two healthy girls and both pregnancies were relatively straightforward so I haven't experienced anything like this before. Anyone been through this? Thanks
