Hi Lynda. I had a nuchal scan last Wednesday. I had the combined scan and blood test which gives a more accurate risk ratio. I had my scan at 6.15pm and had to have a full bladder, but not so full that it was uncomfortable. One lady had to keep going to the loo and empying her bladder a little bit as it was too full! I then had some blood taken to be tested. I had to wait until the following day for the results. Although the Dr who did the scan said everything looked fine it's not until they put the measurements taken from baby into a computer, along with your age and the hormone levels in the blood that they get the results. I came back at a low risk, thankfully. I had to pay for my nuchal, ??200(!), as my NHS authority don't offer a 12-week scan. I say definitely go for the NHS scan too! Once you've seen your lo on the screen at the nuchal scan you won't be able to wait to see him/her again! And to know you will be seeing him/her in 5 days time will be lovely!! Good luck.
