I'm 24 weeks and during my pregnancy iv had 2 vaginal ultrasounds, 2 private ultrasounds where the technician spent 20-40 mins on my belly, 2 very quick ultrasounds with the dr, and a 2 hour anatomy scan as well! From my little research I found out that it's not harmful but now that iv dug deeper iv found more information that states that it could lead to autism and such things. What are your opinions and thoughts??
