Pregnancy with an IUD occurs from time to time in clinical practice. From a scientific point of view, pregnancy with an IUD may affect the development of the embryo because the IUD may have hemostatic drugs, prostate preparations or progesterone. However, clinically there are many children delivered by pregnancy with an IUD, and most of them are conceived because of the displacement of the IUD, so none of them have a significant impact on the development of the baby. However, there are some individual cases, because the intrauterine device on the local organs of the fetus to produce pressure, the development of poor conditions, so the general advocacy of pregnancy with a device as early as possible to terminate the pregnancy, but the specific treatment needs to be decided in conjunction with their own situation. In order to avoid pregnancy with the IUD, you should rest properly after placing the IUD, and avoid walking long distances and doing heavy work on the day of placing the IUD, so as not to cause excessive pressure in the abdominal cavity and cause the IUD to be dislodged. Avoid coitus within half a month after placement, because sexual intercourse is likely to cause uterine contraction and dislocation of the IUD. If there is back pain, lower abdominal pain, or menstrual drip after placing the IUD, you should go to the hospital in time for examination to see if the IUD has fallen off or moved down. You should also go to the hospital for review in the first, third and sixth months after placing the IUD, and at least once a year thereafter, in order to ensure that the IUD is an effective contraceptive.
