I as just wondering, is it really rare for people not to have any scans until the morph scan?

I was tempted to have a dating scan, but I know my dates, and my GP doesn't think I need one. He also doesn't see the need for the NT scan, which is fine with me, cos I don't want that one anyway.
A friend has just told me that I am 'brave' for not having any done until the morph scan. I don't understand how I am brave....

Anyway, I was wondering, how many others out there are not having any scan before the morph scan? Am I in a minority?
Cheers.
