The IUD has become an important contraceptive measure for women because it can achieve the purpose of contraception and does not affect sexual life, easy to put in and take out, safe and effective, etc. 1.What should I pay attention to before and after the IUD? In order to avoid infection, 3 days before and 2 weeks after the operation should be strictly prohibited intercourse, pay attention to vaginal hygiene, do not take a tub bath after the IUD, so as not to cause infection in the uterine cavity. After the operation, you should take rest for 1 to 2 days, and do not do heavy physical labor and heavy sports activities for a week, because the ring is easy to fall off because of the loose opening of the uterus just after the IUD is placed. Women with loose uterine orifices and heavy menstrual flow may lose the ring during menstruation, so you should pay attention to whether the ring falls out with blood when you go to the toilet during menstruation. Generally, after 3 months, 6 months and one year after the IUD is placed, the IUD will be reviewed once. In the future, it can be rechecked once a year. In the 3 months after the ring, especially during menstruation, pay attention to whether the ring falls off, such as found to fall off, to take other contraceptive measures in a timely manner. 2, the birth control ring can be put for several years? Due to the different materials, shapes and whether the ring contains drugs, each ring can be placed for different years, as short as 5 years, as long as 20 years. After the ring is placed, if the ring expires, it is recommended that the ring be replaced at the hospital after menstruation. If you have reached the perimenopause, it is recommended to take out within 6 months of menopause. 3.Can I still have children after removing the ring? After the IUD is removed, its effect of interfering with the union of sperm and egg disappears and the endometrium returns to normal. If you conceive after IUD removal, the fetal development will not be affected in any way. 4.
