When is the best time to get an IUD inserted?

Patient's question:

Medical history: Thalassemia and small ulcers on the cervix
Current general condition: No gynecological diseases, 3 months postpartum

Doctor's answer:

Under normal circumstances, the appropriate time to insert an intrauterine device (IUD) is within 7 days after the end of menstruation without sexual intercourse.
At this time, the endometrium is relatively thin, reducing the chances of bleeding and infection after insertion, and the likelihood of pregnancy is also lower.
Immediately after an induced abortion or mid-trimester induced labor;
For women whose uterus has returned to normal 6 weeks after childbirth;
Within 7 days after a natural miscarriage and the resumption of normal menstruation;
For women whose condition is normal 6 months after a cesarean section;
After childbirth, it can also be inserted after the placenta is delivered. For emergency contraception, it should be placed within 5 days after unprotected intercourse.
