I'm a bit late to the discussion but try not to worry too much Panic - I agree with others that the Harmony should be the most accurate. There is quite a difference between the ratios which seems surprising but the age thing must skew it a lot. If I get chance I'll try and read some of the references about the different tests (I'm a biologist and my last job was in genetics, although I admit I'm by no means a geneticist!)
Super - I'm in Liverpool! Did wonder if you were too based on your name! Whereabouts are you?
Had 16wk (actually 15 due to xmas) MW app this morning - am now seeing a MW at the hospital twin clinic rather than the one I'd originally been assigned at the children's centre. All went fine, usual BP, hand over a pot of wee etc, but we also unexpectedly got to see our babies again as the sonographer at the 12wk scan hadn't written in my notes whether there were 1 or 2 sacs and placentae. I remembered she had told us there were 2 sacs but hadn't mentioned placentae, and which category you fall into dictates the care plan as the risk changes. As it is we have DCDA twins so each have their own of everything - most likely non-identical but also lowest risk. I didn't get to see much of them due to the screen position but DH said it was a lot clearer than last time. It was the consultant who scanned me and he said everything looks great and head measurements are spot on for the age, so am really pleased, and just managed to keep from crying this time! 20wk scan booked in for 22nd Jan, then it'll be 4 weekly appointments - work are going to have to be very understanding!
little - I got Your New Pregnancy Bible which is a tome - only read a bit so far but seems very informative and covers everything. MIL bought DH Pregnancy for Men, which so far I have read more of than he has, but actually it might not be such a bad idea to get something like that as it tends to assume men know nothing about pregnancy so explains it all in simple terms. The other alternative is to go to the library and just pick up a few that take your fancy, then you can buy any if they are good.
Glad to hear MW app went well Gilly and good luck to anyone else with appointments today
