blackbutterfly, thanks for your post. My NT was high, my HcG was high and PAPP-A low, but I'm not sure exactly without looking at the results what they were. Thanks for the info about normal levels, I've been trying to find this out, with no luck, so will be able to compare when I have a look at my notes.
I went for CVS today. I couldn't wait any longer, and they had a slot free this afternoon, so I am now recovering with a sore belly. It does mean I'll get the early results back by the weekend rather than in 12 days time, which is the reason I went for it.
I am still worried but at least I'll know sooner. I was told at my counselling session last week about the new blood test they are trialling, but wasn't asked to take part. What a wonderful thing that would be if they can get it going - would take all the worry about invasive testing away.
Good luck with your pregnancy! And thanks so much for your posts, I've had so much support, I really appreciate it.
