jaffa The individual readings being ok, but combining to make for a higher risk does sound as though it's perhaps your age that is hoiking it up... I think, no infact, I know in your position right now I would be hot fotting it to the FMC for their evaluation given that they check for several other markers (one of which, when I was there, was their newest research and not even published yet!). If a trip to London is completely out of the question then look into somewhere nearer to you that does a more detailed nuchal, checking for soft markers as well as the nuchal translucency. Our babies are indeed precious (not moreso than to a mother who hasn't experienced a loss... but, kinda, y'know?) and I would be doing all I could to stay at the screening level before jumping to diagnostic with the (albeit) small risk that entails.
If I had a worrying detailed nuchal (for instance, no nasal bone seen, and reverse flow in ductus venosus) then I would be more inclined to progress to diagnostic to be sure. If there were no additional soft markers to be seen then that, in hand with my 'average' results with bloods and nt would be massively reassuring.
But that's me 
Maybe give ARC a call? Well, once you have had a little bit of time to get over the shock, which is what it is, no doubt. this is supposed to help, isn't it?
Hey, pebs Af turning up so soon is good news! are you taking your B vits, lady?
midge Sounds grim! The 'not keeping anything down for 24hours' do you think it's a bug, or good old ms? Either way, rehydration is important so if it means 24 hours in hospital to get you sorted (and the difference in how you feel once you're not dehydrated is like night and day!) then so be it!
blue Yes, I'm 38 weeks! And boris you saying it like that is just... Argh! Yes, I will have a baby soon. Me.
