We have to go for a level 2 us on 9-23. I have been looking online (go google) to get a little more information. Has anyone ever had it done? I knew from the beginning that I would need to have the level 2 us because our doc told us right away. I thought he meant a 3D/4D us. I am a little disappointed now beacuse I thought the level 2 us was the really neat 3D/4D us. I know that a person can pay to have the 3D/4D us, but has or is anyone planning on having a 3D/4D us because their dr or mw is requiring it? Thanks...any little bit if info would help.
