For women with regular menstruation, 40 weeks after menopause is the expected date of labor, counting from the first day of the last menstrual period.

Newborns born between 37 and 40 weeks of gestation are full-term babies, so they may go into labor at any time after 37 weeks of gestation, so you should be ready to be hospitalized for delivery at any time after 37 weeks of gestation.
It is recommended that pregnant women and their families should closely observe the performance of pregnant women, and seek prompt medical attention if there are signs of labor such as abdominal pain, vaginal bleeding, or rupture of amniotic fluid. If abnormalities such as increased or decreased fetal movement occur, they should seek medical attention as soon as possible, and terminate the pregnancy by cesarean section if necessary.
