they dont
think so.
They think scans are safe in moderation - so I decided to just have my medically necessary ones. I wouldnt want a very long scan.
I thought i'd miss out the chances of a 3D (non medical) one
just in case...i mean, chances are it's safe, but there have been some people who've disputed it.
Anyway, I personally decided to wait another few months, save my money, because after then i can see my baby is all his 3D glory all I like.
People will say that people have scans every day adn that they have normal babies. But some things wouldnt show up till much later maybe..years after...I dunno...I guess I'm just a bit of a scardey-cat.
