What do you think about ultrasounds during pregnancy? I have already made them 4 times so far (I am 30 weeks pregnant) and I couldn't find much information about the effects. But I have noticed that the baby is not comfortable with it: he is hiding his face, or turning with his back, he is waking up if he was asleep before...Though it is really nice to see him, I would go for safety first, and if I go to doctor, that's the first thing they would do to check if everything is alright.
