First post. This is absolutely terrifying. I'm posting mostly because I've found it helpful to read about others' accounts.
"No result" from Harmony test (first attempt). Nuchal test on Friday, came up with 1:4 for T21, and 1:6 for T13/T18. CVS scheduled for Monday afternoon. [If anyone is interested in the basis for the 1:4 result: Papp-A and beta HCG both very, very low; NT at what I think is the high end of normal (2.1); and tricuspid regurgitation...on the plus side, baby has weirdly long legs, and nasal bone present, and is otherwise structurally normal.]
Do I need to do anything to prepare for CVS? Do they scan you again before doing the CVS?
