The placement of a birth control ring into the body is an invasive procedure. This procedure is performed in the vagina, which needs to be sterilized when the menstrual period is clean, and a perineal speculum is used to dilate the vagina, and the appropriate length is placed at the bottom of the uterine cavity according to the depth of the uterine cavity. Although the IUD can be used as an effective contraceptive without affecting ovulation, it is recommended to go to the relevant hospital for a corresponding examination to see if it is suitable for use of the IUD before using it. The IUD cannot be moved when placed in the uterine cavity, and as the IUD is a foreign object in the body, the sensitive body may also have a reaction of rejection. The IUD is not 100% contraceptive, and as you get older, you may experience abdominal pain and bleeding, and if you are older, the process of removing the IUD is more painful. If you want to use the birth control environment is recommended to go to the relevant hospital to do targeted examination, combined with the doctor’s comprehensive judgment.
