When I was pregnant, a million years ago, we had, for an uncomplicated pregnancy, a dating scan at 12 weeks, and an anomaly scan at 20 weeks (I think- it was a long time ago!) That was it, unless there were any concerns.
People seem to have a lot more now-particularly very early ones. It seems to me that, considering the frequency of early miscarriage, for example, they must just increase anxiety and stress? I certainly think they would have for me. I don't understand how they are of any benefit. Presumably they can't provide much useful information, and just add to the grief if the worst happens. Or am I missing something? I suppose I'm also influenced by the fact that in my day, we tried to minimise scans because there was some concern among some people that ultrasound could be damaging to the baby. I know that's been shown not to be true, but it's still there in my head! I remember worrying because I had to have more-my babies were enormous!
