How long does it take to remove the birth control ring depends on whether the position of the ring is normal. If the position of the IUD is normal, most of the metal IUDs are valid for 10 years after the IUD, and can be replaced with a new IUD after 10 years. If the IUD is made of plastic, it is only valid for 5 years after it is inserted into the uterine cavity, so it is recommended that the old IUD be removed in 5 years and replaced with a new one if you want to continue contraception. Whether you want to take out the IUD or put in the IUD, it is recommended not to have intercourse within 3-7 days after menstruation, and to have normal outpatient laboratory tests for white belt routine, blood count, clotting time and gynecological examination before you can put in or take out the IUD.
