With my son I had two ultrasounds - the nuchal scan at 12 weeks, and the anatomy scan at 18 weeks. We didn't take it easy with the doppler, either. He's now left handed (which doesn't run in either family) and very hyperactive. I wonder how much of it can be attributed to all the ultrasound he was exposed to.
This time, I have been wavering on the anatomy scan. I expect we'll allow a doppler at our first appointment so Husband can hear the heart, but only fetoscope after that. No nuchal scan for sure, and we're not convinced on even getting the 20 week scan. I've done my research, and I know the risks are high even for a single exposure. But there are two factors that make me think the anatomy scan might be a good idea. The first is that we're probably going to have a UC, and it would be nice to know that everything is ok (and that there's only one baby, which is a concern). The second is that I have an extreme preference for a boy, to the point that I am already starting to get depressed at the thought of having a girl, which I feel this baby is. If I am able to find out the sex ahead of time, I feel it might help me to get used to the idea and have a plan to address my depression when she comes.
What do you think? In my situation, would you have the anatomy scan, despite the risks? Would you try to limit the length of it (I'm thinking of putting a 15 minute limit on it, and walking out if it goes longer)?
