I went for my U/S and TVUS this morning. I don't have the results yet, of course, but did manage to sneak a peek of the screen when the tech left the room. The first time she left, I saw "7.0 cm" in the bottom corner. This was a measurement from the TVUS, as she had just finished. She then came back in, mentioned something about taking more measurements due to the "physics" of something or another, and looked via U/S.
