A woman usually carries a child for ten months. Normally it is more accurate to calculate by the number of weeks. Due to the individual circumstances of pregnant women, it is normal to give birth between the 37th and 42nd week of pregnancy, i.e. between 259 and 294 days. After 42 weeks of pregnancy, it is called an expired pregnancy, when the function of the placenta gradually declines and the mother’s physical condition cannot continue to support the development of the fetus. At this point, an artificially assisted delivery method such as a Caesarean section or a late-term induction of labor is required to deliver the fetus and terminate the pregnancy. Regular ultrasound checkups are needed to determine the status of the pregnancy. Early in pregnancy, you need to eat foods that are high in nutrients and dietary fiber, and control your intake of fats and sugar.
