It is possible for a woman wearing a birth control ring to cause inflammation, as it may cause damage to the cervix and the lining of the uterus. During the process of placing the IUD, it may cause some damage to the cervix, which may easily cause inflammation. At the same time, if the operation is not standardized or the instrument is not sterilized well, it is also easy to carry bacteria, fungi and other pathogenic microorganisms into the vagina, causing gynecological inflammation. After placing the IUD, because the IUD is a foreign body in the body, it may cause different degrees of damage to the uterine lining, and a small amount of vaginal bleeding occurs. If the vulva is not cleaned properly, pathogenic microorganisms can easily invade the body through the vagina and cause inflammation. To summarize, after placing the IUD, you need to pay attention to the cleanliness and care of the vulva, keep the vulva dry and pay attention to rest. In addition, after the next menstrual period, it is recommended to review the position of the IUD to see if it is normal, so as to avoid displacement of the IUD.
