Only 5 percent of women deliver on their due date, according to American Academy of Pediatrics.A healthy pregnancy is, on average, 40 weeks from the last menstrual period, but in reality, most babies come sometime between 37 and 42 weeks gestation.For many women, that five-week window creates a waiting game that can feel unbearable.
