Before shedding Sheung Wan, we must have an understanding of all aspects, especially the precautions before Sheung Wan, and it is particularly important to grasp the best time in Sheung Wan.
Precautions before Sheung Wan to grasp the best time in Sheung Wan:
1. Place when menstruation is not clean. Menorah of menstruation is placed on days 3-5.
There are three benefits to this period of time:
First, the uterine mouth is loose and easy to put in.
Second, menstruation has just arrived, which can rule out pregnancy and will not mistakenly put the ring into the womb that is already pregnant.
The third is to avoid the concerns and inconveniences caused by the small amount of bleeding caused by the release of the ring.
2. Place after menstruation is clean. 3-7 days after menstruation is clean, there is no sexual life history to put the ring is appropriate, because at this time the endometrium is just beginning to grow, the lining is thinner, and bleeding can be avoided when placed, and there is no sexual life after menstruation, which also avoids the possibility that the fertilized egg has grown on the endometrium when the ring is released. In general, most women choose to put the ring at this time.
3. Immediately after childbirth, release the ring. At this time, the placement of surgery is simple and easy, and contraceptive measures can be implemented in time, but it can only be placed after approval by the obstetrician.

4. Placed 42 days after childbirth. That is, it is placed at the same time as the health examination about 42 days after childbirth, and the advantages of placement at this time are: First, the uterus is loose. Second, the uterus has returned to normal size and has not shrunk due to breastfeeding for too long. Third, contraceptive measures have been implemented in a timely manner, which is convenient for women and can avoid the occurrence of dark fetuses.
5. More than three months after childbirth can also be released. However, it should be noted that if this time is the lactation period, although there is no menstruation, there is still a possibility of pregnancy, which is what people usually call dark fetus, so women who have not yet come to menstruation after childbirth should first ask a doctor to check whether they are pregnant, and then they can release the ring in the case of confirmed pregnancy.
6. Immediately after the abortion or forced curettage surgery, the ring is released. The advantage is that contraception is implemented at the same time as one operation, which reduces suffering and facilitates women.
7. Release the ring after normal menstrual recovery after spontaneous abortion or artificial abortion after curettage.
8. Caesarean section at the same time or surgery for half a year, the situation is normal, you can also consider releasing the ring.
9. If the previously placed ring has reached the end of its life and requires a ring change, a new ring can be put in while taking the ring. It is also possible to put in a new ring after the next menstrual period is clean. However, it must be remembered to pay attention to contraception in the month after the ring is removed.
