Riley really sorry to hear your news. Will be thinking of you.
Twinkle, good luck on Monday.
Sparkly, I found out at a nuchal scan last August that our baby had Trisomy 13 so I know what your friend is going through. Although it is true that the nuchal gives an idea of the risk of an abnormality and is not a diagnostic test, there are so many problems with Trisomy 13 that they can pretty much tell for certain from a scan. In our case, and it sounds like the same for your friend, the CVS is to confirm what they already know and also to ensure there is not a genetic problem with one of the parents (as then there is a higher recurrence risk.) It is an absolute nightmare to go through. One thing I'd say to you, is that some of our oldest friends completely ignored us for a few weeks after it happened, to give us 'space'. This made me feel really isolated. Your friend may be someone who wants her privacy, but I would say from bitter experience, that it is really important that she knows that her friends are there for her.
Anyway sorry for that essay-obviously it is a subject close to my heart.
On a lighter note, I am also someone who has a bump already. It is ridiculous. With DD I didn't need maternity clothes til about 20 weeks or something. I don't know what is going on. I don;t think twins is the excuse in my case-have not felt ill enough and there are no sets in my family. So it must be too much cake.
