Glad your scan went well. I felt much the same going for my NT scan. If your results don't come back as well as you expected don't go into a mad panic. It's just a risk factor, not a result.

My 22 week scan was the first scan (and my 5th in total) that I didn't expect them to tell me there was no heartbeat. This time I thought they were going to tell me my little boy was a bit small but instead I got the news that he's 5 days ahead growthwise. Sometimes you just get a nice surprise.
