I've had 2 dating scans (Because they couldn't find anything on the first one). The NT scan, the 19 week scan, a quick scan at the ob the other day and I am having another scan at 34 weeks.

This is my second bub and I do feel like I have had too many scans because with my first I only had 3 for the entire time. I wish I didn't have the dating scans but I am happy that I had the NT scan. But that's just me.

There was a thread about this a few months ago when it was in the media a bit.
