The term “IUD” generally refers to the placement of an intrauterine device (IUD). Generally, women who become pregnant with an IUD do not need to remove the IUD first, and if the ultrasound monitors the normal development of the embryo, it will not usually affect the growth and development of the fetus. The main purpose of IUD placement is to prevent pregnancy, but this method does not guarantee the success of contraception. The position of the IUD is often shifted in pregnant women with an IUD. In the case of an unwanted pregnancy, if the embryo develops normally on ultrasound monitoring and if there is a desire to have children, there is no need to remove the IUD. Removal of the IUD is a bedside operation and may cause abortion of the embryo. The IUD can mostly be expelled with the placenta after delivery of the fetus. It is recommended that women who are pregnant with an IUD in place and have the desire to have children should adjust their mindset and follow the doctor’s instructions to see the doctor on time for obstetric checkups. If the pregnancy is accompanied by vaginal bleeding, lower abdominal pain and other uncomfortable symptoms, it is necessary to consult a doctor in time.
