I thought the scariest part of a 12 week scan would be discovering a MMC, so to see my baby on the screen wriggling about with a nice heartbeat I instantly felt relief. Measurements were done and the midwife never mentioned anything wrong with those. However the NT was 3.4mm which I googled later and found out was high. I called yesterday to chase up the combined score with bloods and was devastated to be told we have a 1:5 chance of chromosome abnormalities. I don't actually have my individual blood levels but assume they were also off. Getting the harmony test done this afternoon but it will be a long wait for the results. I just don't know what to do with myself.
