Normally, the IUD should be reviewed two weeks after placement and should only be used for intercourse after the IUD is basically stable. If you start having intercourse too early, it may lead to changes in the position or shape of the IUD, or cause the IUD to fall off, and may also lead to gynecological inflammation, such as vaginal inflammation, pelvic inflammation or cervical inflammation, in women who have had the IUD placed. After half a month or so, the position and shape of the IUD has basically stabilized, and the vaginal bleeding and mild abdominal pain should have disappeared by this time, so you can have sexual intercourse. In addition, it should be noted that the patient should pay attention to the hygiene of sexual life, and the condition of the IUD should be reviewed regularly after the placement of the IUD.
