The Stranger Within (1974)

Her unborn baby orders her to ignore her doctor...Forces her to abandon her husband...And compels her to do what no woman has ever done before...Who Is This Child?

Who is the father of Ann Collins’ baby? Her husband had a vasectomy years ago. And Ann hasn’t been with another man. Even more mysterious: as the baby grows inside her, Ann begins to change. She is beset by strange illnesses, pours tablespoons of salt on her food, turns the thermostat to 50 degrees, speed-reads academic tomes. But much bigger shocks are yet to come. Barbara Eden stars in this hypnotic, swiftly paced blend of horror and sci-fi from Richard Matheson, the popular and prolific writer who also penned the novel I AM LEGEND and several notable THE TWILIGHT ZONE scripts.
