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.
