I want to have a 3D/4D ultrasound that shows incredible images of your baby. I'm now at week 21. I was concerned about risks and read it's no different that regular 2D ultrasound in your doctor's office, but research talks about risks with numerous ultrasounds in general (regardless of which kind). I already have had 4 or 5 already b/c of concerns with previous miscarriages and screening tests b/c I'm over 35 (so with nucheal transluceny and amnio), but wonder if it's reckless to have yet another ultrasound (the 3D one) just for fun and not medical reasons. Again, it's the same effect on the fetus but the question is -- is it bad to have one when not medically necessary?? Has anyone done it or considered doing it now? I know the sex of the baby, which is one reason women don't seem to want the ultrasound.
