a friend of mine recently told me about recent studies telling that more than 4 u/s during pregnancy imply risks for the baby. I still don't get the reference for that friend, but I have found other articles sharing that concern: http://www.wsj.com/articles/pregnant-women-get-more-ultrasounds-without-clear-medical-need-1437141219
What do you think? Any of your ob/gyn agreeing with that? Do you think the risk worth it?
