A woman will not have an IUD immediately after giving birth. It takes time from the delivery of the placenta to the return of all organs of the body to their prenatal state, except for the breast, which is called the puerperium, which is 6 weeks and includes the recovery of the uterus during this period. It takes 6 weeks from the size of the uterus at 12 weeks of gestation to the size of the non-pregnancy period, and it takes 4-6 weeks for the discharge of malodex, so it is not possible to have intercourse, and it is not possible to have an IUD. In most cases, the postpartum IUD should be after breastfeeding and natural menstruation. It should be emphasized that during breastfeeding there is a possibility of ovulation even during future menstruation, and safe contraceptive measures should be taken during intercourse, such as condoms, to avoid pregnancy during breastfeeding, or oral contraceptive pills can be taken if not breastfeeding. Women should eat reasonably during the puerperium, keep their bodies clean, pay attention to rest, and move appropriately as early as possible to facilitate physical recovery.
