A 42-year-old woman who has an IUD will not usually get pregnant and have a baby as long as the ring is in the right position. If the ring is displaced or removed, it is possible to get pregnant and have a child, but 42 years old is a senior age, if you have a request for a child, it is recommended to prepare for the pregnancy test. The main purpose of the intrauterine device is to interfere with the sperm-egg bonding and the embryo’s ability to settle in the uterus, thus achieving the goal of contraception. However, if the ring is dislocated or removed, it will not interfere with the sperm-egg bonding, so the fertilized egg will most likely implant normally. However, 42-year-old women are of advanced maternal age, and are advised to prepare for pregnancy tests if they wish to have children, and to follow the doctor’s instructions for regular checkups after pregnancy. Therefore, pre-menopausal women have the possibility to get pregnant, if there is no requirement for childbearing, they need to take effective contraceptive measures in their life.
