There are eight golden periods in women's upper ring. Don't be careless after having too much menstruation.

The IUD is placed in the uterine cavity of women of childbearing age to achieve the purpose of contraception through mechanical stimulation and chemical interference, which does not inhibit ovulation and does not affect the female endocrine system, thus avoiding the adverse reactions of general drug contraception.

There are a variety of suitable times for IUD placement:

1. Placement during menstrual week: generally, it is more appropriate to place it within 3-7 days after menstruation, because of the opportunity to get pregnant during this time.

It is very small, and the endometrium is proliferative, the endometrium is thin, and there is less chance of injury and bleeding after placement. Foreign countries also choose to place in the menstrual period, so the possibility of pre-implantation pregnancy can be ruled out, and the cervix is loose, the operation is easy, and the psychological burden of uterine bleeding after placement can be avoided.

2. Place immediately after induced abortion: immediately after induced abortion or forceps curettage, the uterine mouth is loose at this time, and the second operation can be avoided. In some studies, compared with the placement during the menstrual cycle, the complications of infection and bleeding did not increase, and the rates of pregnancy and prolapse were also very similar. But you must make sure that the contents of the uterine cavity are completely cleared, there is not much bleeding, and the uterus contracts well before it can be placed. If there is irregular vaginal bleeding before operation. If there is much bleeding during the operation, the uterine contraction is poor or the contents of the suspicious uterine cavity are not completely removed, wait until the next time after menstruation.

3. Placement after induction of labor in the second trimester of pregnancy: immediately after the second trimester of pregnancy without transvaginal operation, such as abdominal puncture of amniotic cavity rivanol to induce labor, after the delivery of the fetus, it was placed during the operation of uterine clearance. The IUD is placed after induced labor in the second trimester of pregnancy, generally speaking penispumpe vacuum pumps , the drop-out rate is as high as 5-10 times that placed after early abortion, so if it is suspected that there is a possibility of residual tissue in the uterine cavity, potential infection and vaginal induction of labor with water sac or other drugs can not be placed.

4. 42 days after delivery and amenorrhea during lactation, if pregnancy is excluded and uterine contraction recovers well, lochia is clean for more than 5 days, and there is no uterine cavity or perineal infection, an IUD can be placed to reduce pregnancy during lactation. However, because the myometrium is fragile and thin, you should be careful when placing it so as not to perforate.

5. Cesarean section should be placed half a year later.

6. the placement of the IUD expires without any symptoms and can be replaced immediately after the IUD is removed.

7. Placenta is placed immediately after delivery and cesarean section, its advantage is that delivery and placement of IUD are completed at the same time to avoid secondary operation, and the disadvantage is high detachment rate. Such as breaking water for more than 12 hours, delayed labor, vaginal operations such as surgical delivery, hand extraction of placenta, etc., are easy to cause infection, so it is not appropriate to place IUD. Suspected placental residue, due to the possibility of bleeding, it is best not to place IUD. Classical cesarean section, because the uterine incision is located in the body of the uterus controller vibrator , IUD is easy to incarcerate from the incision, or penetrate the uterine wall into the abdominal cavity, generally not put; even if it needs to be placed, it must be carried out in hospitals at or above the county level.

8. Place after sex (after sexual intercourse). Women who are worried about pregnancy due to failure to take contraceptive measures or accidents due to contraceptive measures (such as broken condoms) after sexual intercourse, and are prepared to take long-term birth control measures, can place copper-containing active IUDs within 72 hours.

Although there are a variety of placement time mentioned above, most of them are placed within 3 to 7 days after menstruation.

Don't be careless with excessive menstruation after putting on the ring.

The upper ring is to put the IUD into the uterine cavity, so as to achieve the purpose of contraception. It is a contraceptive method favored by many women at present, especially for women who have given birth, the birth control ring, as a foreign body, causes a mild, chronic, non-bacterial inflammatory reaction in the endometrium, thus changing the uterine environment and preventing egg implantation. And the phagocytes produced by it have the effect of phagocytosis and destruction of spermatozoa. IUD can stimulate the uterine cavity to produce prostaglandins, make the uterus and fallopian tubes contract and peristalsis abnormally, and enhance the effect of estrogen at the same time, so that the environment in the uterine cavity is not conducive to implantation. And it is made of metal copper, it can achieve the purpose of contraception through local changes in the internal environment, such as uterine intima and uterine fluid, and its toxicity to sperm.

A few days after the release of the ring, there can be a small amount of "red" in the vagina, this is because the ring scratched the cervix or endometrium, or the ring oppressed the endometrium, the infiltration of inflammatory cells, there will be pink leucorrhea or a small amount of vaginal bleeding, this is a normal phenomenon. In a few days, everything will be back to business as usual. A small number of women have the phenomenon of excessive vaginal bleeding, prolonged menstruation and menorrhagia after ring release. Most women have a menstrual period of about 5 days, and the amount of blood loss in a menstrual cycle is about 30ml. After putting the ring, if the bleeding is the same as when menstruation comes dildo squirt , that is "the amount of bleeding is much". The first menstrual volume after putting the ring is 1-2 times more than the original, and the menstrual period is more than 9 days, which also belongs to menorrhagia, causing irregular menstruation.

First, the reason for menorrhagia after the ring is

1. After ring release, prostaglandins increase in women, which can inhibit platelet agglutination, dilate blood vessels and increase vascular wall permeability, resulting in an increase in the amount of bleeding.

2. The birth control ring increases the activity of fibrinolytic enzyme, causes fibrinolysis, and is easy to cause blood coagulation disturbance, which leads to a large amount of bleeding.

3. The IUD oppresses the endometrium, resulting in local congestion and edema. However, after 3-6 months of self-repair and regulation, it will gradually improve.

2. So who can't place an IUD?

3. The uterine cavity is smaller than 5.5cm and larger than 9cm.

4. Patients with frequent menstruation, menorrhagia (except levonorgestrel-IUD) or irregular vaginal bleeding within one month. The hasty reproduction of birth control devices will aggravate the disease.

5. Inflammation of reproductive organs, such as vaginitis, acute or subacute cervicitis, acute and chronic pelvic inflammation, sexually transmitted diseases, etc., untreated and uncured.

6. Patients with loose internal orifice, severe tear (except copper fixed IUD) and severe stenosis.

7. Hydatidiform mole has a history of less than 2 years.

8. Reproductive organ tumors, such as uterine fibroids and ovarian tumors, should be used with caution.
