The editor of the IUD reminds the precautions after the ring is placed:

After resting the ring, rest for two days, avoid heavy physical work for one week, and ban bathing and sexual intercourse for two weeks.

There may be a small amount of vaginal bleeding or slight backache in the first few days of ring placement, and it will naturally disappear within a few days without treatment. If the bleeding is heavy and there is abdominal pain, the cause should be investigated after treatment.

After the ring is placed, it should be reviewed after the next menstruation for pelvic fluoroscopy, and B-ultrasound can also be used. Check again after 3 months, and check again every year thereafter.
