The IUD has not been clean after abortion may be caused by the IUD affecting the recovery of the uterine lining after abortion, or it may be caused by the side effects of the IUD. Generally, you can relieve the treatment through medication, and if necessary, you can do the treatment of removing the ring. Because abortion can cause damage to the uterine lining, and the IUD will stimulate the uterine lining, which may cause the uterine lining to fall off and bleed, so there will be a situation that the IUD has not been clean. You can take oral sex hormone drugs, such as medroxyprogesterone, estradiol valerate and norethindrone. Side effects of IUD include irregular vaginal bleeding, increased leukorrhea, abdominal pain, lumbar pain, displacement of the birth control device, and pregnancy with a device. Oral antibiotics can be taken to treat secondary infection caused by IUD. Oral hemostatic drugs such as adrenochrome tablets and phenolsulfonamide can also be taken. If the patient’s symptoms are more serious, you can consider the intention of removing the IUD and find other methods of contraception. If the patient has the symptom that the IUD has not been clean after abortion, it is recommended to go to the hospital for treatment in time to avoid delaying the condition.
