Re: Are sonograms really safe??
From what I've read of them, I wouldn't want them done more than 1-2 times per pregnancy, unless of course you have some major issues. I also would suspect that the 3d/4d would be the worst ones to have. That technology is just much too new for me to trust.
I almost rented a doppler with my 2nd DS for entertainment purposes, but quickly decided against it.
