Thankyou to all who have replied.

After a sleepless night and long conversation with my partner about what we should do (he is freaking out way more than I am), and a long chat with a close friend who is a doctor (who also did amnios for both her children - she was over 37) I think I’ll now be be opting for the amnio. I’m feeling as Sloane is, I don’t think I or my partner can relax until we ‘know’ for certain. The only way is the amnio.

I guess after looking at the actual numbers and the calculation they came up with I am actually feeling a little more comfortable about the fact that it really is just ‘a number’, and although on the borderline, you can never be certain of the result.

I’m feeling that it might actually bode well for me given my scan was excellent and presence of the nasal bones. Either that or I am just too damn positive for my own good.
