The expiration of the IUD does not usually cause any physical symptoms, but it can also lead to unwanted pregnancies or gynecological infections.
As the IUD is a contraceptive ring, the expiration of the IUD does not usually have a self-feeling, and you cannot determine whether the IUD has expired or not from its appearance or how you feel about it.
When the IUD expires, the contraceptive effect may decrease, or may not even be effective, and intercourse may lead to unwanted pregnancy or gynecological inflammation, such as cervicitis, endometritis, pelvic inflammatory disease, and so on.
You can calculate the expiration of the IUD from the time, if it is expired, it is recommended to consult a doctor in time and have it replaced by a professional doctor or use other contraceptive methods in time to avoid unwanted pregnancy or side effects of the IUD.
