The postpartum checkup does not have to be performed strictly on the 42nd day, and can be delayed appropriately, but the latest delay should not be more than 2 weeks. The purpose of the postpartum checkup is to determine whether the postpartum recovery is smooth and to observe whether the uterine contractions and other conditions are normal. Since the puerperium period of a woman is 6 weeks, or 42 days, women are generally required to undergo the checkup on the 42nd day after delivery. Under normal circumstances at this time, the functions of the female reproductive organs, except for the breasts, have returned to their pre-pregnancy levels. However, there is no strict time limit for the postpartum checkup, if there are objective factors that make it inconvenient for the time being, the checkup can be delayed appropriately, and the delay time should not be more than 2 weeks. If there is any physical discomfort after delivery, it is recommended to consult a doctor in time and carry out standardized treatment under the doctor’s guidance.
