I've had ultrasounds in all of my pregnancies, only 1 or 2 each, but I had no idea until relatively recently that there was any controversy surrounding them. We did have one yesterday- we decided to do it for dating, but mostly because we both really wanted reassurance that all was well in there. The doc who performed the US suggested we could come in around 12 weeks for testing, or wait till 20 weeks for an anatomy scan. If we did both, that'd bring us to three ultrasounds, and I'm not sure whether we should be concerned about that much exposure.
What are other mamas deciding to do? Are you worried about US? Avoiding them altogether? Unconcerned?
