It is normal to have light pink discharge within one month after the IUD, the IUD may stimulate the uterine lining, resulting in a small amount of bleeding symptoms, it is recommended to take oral antibiotics and hemostatic granules to stop bleeding after the IUD treatment. If you still have light pink discharge more than one month after the IUD, you should go to the hospital regularly for ultrasound examination to see the position of the ring, because if the position of the ring has moved, or the ring is embedded in the uterine myometrium, it may also lead to the symptoms of abnormal bleeding. If the IUD is an imported medicated IUD such as Mannuelle, it is normal to have spotting bleeding and pink discharge after menstruation because it contains progesterone, and the release of a certain amount of progesterone every day may stimulate the endometrium, so there will be a light pink discharge. If all the test results are normal and you have a normal ring, it is possible that the ring does not match, in which case you need to have the ring removed or replaced.
