Other mistake: When Jenna was having her ultrasound, the doctor picked up a linear probe. This probe is only used for vascular purposes (arteries, veins) and cannot go deep enough to show an unborn baby. It also produces a rectangular image on the screen. The doctor should have used a curved probe which produces a curved image on the screen, which is exactly what was shown in the next shot.

Old Joe: Are you with child?
Jenna: Shush.
Old Joe: I saw that look on a woman's face before. Her name was Annette. I made sweet sweet love to her all through the summer of 1948, and she had that look on her face all through the fall.
