Got my results, they rang today. The risk is 1 in 120. The hormone which concerned them is low Papp-A. (0.47).
It's considered high risk, but nowhere near as high as I had been worrying about (I was bracing myself for something like 1 in 5) seeing as last time round the risk was 1:17.
They say the risk of CVS is 1 in 100 miscarry. However last time I had a CVS and I remember the consultant who performed it said the risk was actually much lower,like 1:200 and I think she implied it depends on the skill of the person doing it, so don't know what to believe. She was very experienced, maybe she was just trying to reassure me?
Last time the decision to have a CVS was easy given the high odds. This time not so easy, it's a horrible game of numbers.
I asked if the sonographer had seen a nasal bone, and the midwife said she hadn't said either way on the notes. She's going to book me in for a scan for the nasal bone and other indicators of chromosomal abnormalities in the next couple of days, with a consultant, so i'm pleased about that, as it'll give us more info.
