Position and Presentation of the Fetus

    Toward the end of pregnancy, the fetus moves into position for delivery. Normally, the position of a fetus is facing rearward (toward the woman’s back) with the face and body angled to one side and the neck flexed, and presentation is head first.

    An abnormal position is facing forward, and abnormal presentations include face, brow, breech, and shoulder.
