Each episode features two or more women who were unaware that they were pregnant until they went into labor. Frequent reasons for the subjects not recognizing pregnancy include: • Mistaking the symptoms for another condition or illness. • Believing they were infertile, and thus not considering pregnancy a possible cause of symptoms. • Not having any of the "traditional" symptoms. • Assuming their birth control methods were 100% effective. • Vaginal bleeding during pregnancy being misinterpreted as a period. • False negative pregnancy tests.
