In the case of a normal delivery, it is recommended that the IUD be placed at least 3 months after delivery; 6 months after a cesarean section is preferable. If you are already menstruating after delivery, it is most appropriate to have the IUD inserted 3-7 days after your menstrual period has cleared; if you are not menstruating, you need to make sure you are not pregnant. Women who want to have an IUD need to go to the hospital for a review 42 days after delivery to observe the recovery of the uterus, and if the physical condition permits, it is recommended to use a birth control ring with copper. At the same time before the IUD need to improve the gynecological examination, to determine that there is no gynecological inflammation before the IUD, otherwise not on the IUD. After the IUD, you need to pay attention to the following aspects: 1, pay attention to hygiene: wash the vulva every day after the IUD is put in place, keep it clean, don’t sit in the basin and take a bath within 2 weeks, and don’t have coitus within 2 weeks, so as to avoid infections; 2, take proper rest: avoid overweight physical labor, and generally take a rest for 1-2 days after the IUD is put in place to avoid the IUD from falling off and bleeding; 3, review in discomfort: if you find that there is a lot of vaginal bleeding which is more than twice the usual menstrual bleeding, or the bleeding time is longer, then you should take a good look at the IUD. If you find that the vaginal bleeding is heavy, more than double the usual menstrual blood volume, or the bleeding time is longer, and the change of menstrual cycle is more obvious, you should go to the hospital for examination. Generally, the first checkup after IUD release is after the first menstrual period, the second is within 3-6 months after IUD release, the third checkup is 12 months after IUD release, and the checkup is once a year thereafter.
