The upper ring is also divided into periods, in order to achieve the best purpose of the upper ring. Lucky Grass lists five golden periods for you in Shanghuan:

Menstrual cycle

In general, it is more appropriate to place it within 3-7 days after menstruation is clean, because the chance of pregnancy is very small during this time; and the endometrium is proliferative period, the endometrium is thinner, and the chance of injury and bleeding after placement is less. Foreign countries also have the choice of placement during menstruation, so the possibility of pregnancy before placement can be ruled out, and the cervical opening is loose, easy to operate, but also to avoid the psychological burden of uterine bleeding after placement.

2. Afterwards

Women who do not take contraceptive measures after sexual intercourse, or who are worried about pregnancy because of the unexpected occurrence of contraceptive measures, and who are prepared to take long-term contraceptive measures, may place active copper-containing contraceptive devices within 72 hours.

3. Post-abortion

After artificial abortion or forceps curettage, the uterine orifice is relaxed and the second operation can be avoided. Some studies have shown that compared with placement during the menstrual cycle, the complications of infection and bleeding have not increased, and the pregnancy and abscission rates are similar. But we must make sure that the uterine cavity contents are completely cleared, the bleeding is not much, and the uterus contraction is good before placement. If there is irregular bleeding of vagina before operation. If bleeding is excessive, uterine contraction is poor or suspected uterine contents are not completely cleared, they should be put back after the next menstruation.

IV. Mid-term Pregnancy after Induced Labor

Immediate placement after the second trimester of pregnancy without vaginal surgery, such as abdominal puncture, amniocentesis, and rivanol induction, is performed after the delivery of the fetus and during uterine clearance. In general, placement of contraceptives after induction of mid-term pregnancy has a high rate of abscission, even up to 5-10 times as high as placement after early abortion. Therefore, if there is suspected residual tissue in uterine cavity, there may be potential infection and water sac or other drugs can not be placed by vaginal induction.

5. Placental delivery during delivery and after cesarean section

The advantages are that delivery and placement of contraceptives are completed simultaneously, avoiding secondary surgery, and the disadvantages are high dropping rate. If water breakage is more than 12 hours, obstetric delay, vaginal operations such as surgical delivery, hand placenta removal, etc., are easy to cause infection, so it is not appropriate to place the contraceptive device. Suspicious placenta remnants, because of the possibility of bleeding, it is best not to place an IUD. Classical cesarean section, factor uterine incision is located in the body of the uterus, IUD is easy to incarcerate from the incision, or penetrate the uterine wall into the abdominal cavity, generally not put; even if need to be placed, it must be carried out in hospitals at or above the county level.

Keep in mind that contraceptives can be placed in those with 42 days postpartum and lactation amenorrhea, except pregnant women, whose uterine contraction recovers well, lochia is clean for more than 5 days, and those without uterine cavity or perineal infection, in order to reduce lactation pregnancy. However, the uterine muscles are fragile and thin, so we should be careful when placing them in order to avoid perforation.
