The expiration of the birth control ring without removing it will definitely have an effect on the body. First of all, if a woman of childbearing age has an expired birth control ring, it is recommended to replace the ring as soon as possible or remove the ring, otherwise the ring will be too long, which will cause the ring to be deformed, embedded, or even dislocated to the pelvic cavity, resulting in very serious consequences, and the ring will also lose its original contraceptive effect after the expiration of the ring, which will lead to the possibility of pregnancy and the need to have an abortion. If the IUD is not removed after menopause, it will be even more harmful, because about half a year after menopause, the genitals will atrophy, and after the uterus atrophies, the IUD is relatively too big in the past, which will cause recurrent pain in the lower abdomen, or even vaginal bleeding, or the IUD will be worn out from the uterus and dislocated to the pelvic cavity, which will cause serious consequences, so the IUD will be taken out as soon as possible after its expiration or after the menopause.
