A 41-week pregnancy is not considered to be an overdue pregnancy, but a delayed pregnancy is considered to be 41-41 weeks plus 6 days, while an overdue pregnancy is defined as a pregnancy that has reached 42-42 weeks or more. After 43 weeks of gestation, the perinatal mortality rate can increase more than three times compared to the previous one. In addition, the incidence of large babies increases with gestational age, and the rate of obstructed labor and cesarean delivery increases.
