For the 42-day postpartum review, you will usually go to the obstetrics department and the bedside doctor will tell you when and where to come for the review before you leave the hospital. If you are not sure, you can take the initiative to communicate. The 42-day postpartum checkup is very important for women because after the puerperium, most women’s uterus can return to its pre-pregnancy state by this time, but a few may have their own special conditions. During the review, it is important to know whether the dew is clean or not, and if necessary, to perform a gynecological ultrasound to know whether there is residue in the uterus, because some mothers are overworked during the menstrual period with the baby, or the uterus is not contracted well after delivery, or there is placenta residue in the uterus, which can cause the dew to be incomplete. Therefore, regardless of whether it is a normal birth or a cesarean birth, it is recommended that each woman should go to the obstetrics department of a local hospital (preferably the hospital where she gave birth) for a review after 42 days after delivery. If the ultrasound indicates residues, the decision will be made on a case-by-case basis to treat them with medication or a curettage. In short, every mother 42 days after delivery is recommended to go to the hospital on time for a review, of course, with the baby at the same time the mother should pay attention to rest.
