Having intercourse 14 days after the IUD is inserted will not cause the ring to move downward, and it is very rare for the ring to move downward due to too much intercourse. It is not recommended to have intercourse in the same month after the IUD is placed. It is necessary to prohibit sexual intercourse for 1 month, and then consider having intercourse after the next menstrual period. The IUD has just been placed, and its bond with the lining of the uterus is not very strong, and may move due to external factors, such as too vigorous or frequent coitus. However, after 2 weeks with the ring, the position of the ring is basically more stable, and coitus generally will not cause the ring to move down. Intercourse within 1 month with the IUD will mainly cause infection in the uterine cavity, lower abdominal pain, vaginal bleeding and other symptoms. Therefore, you should pay attention to maintaining physical hygiene and forbid sexual intercourse for the time being after the implantation of the IUD.
