It is normal for the patient to have blood in the leukorrhea within 10 days of the operation, because the patient usually bleeds for about 7-10 days after the operation. During the first 3 days of the operation, the patient’s vaginal bleeding is slightly more, and after 3 days, the vaginal bleeding gradually decreases, so it gradually changes to blood in the leukorrhea, even with blood. If the patient still has blood in the leukorrhea 10 days after the operation, it is abnormal. In this case, the patient should undergo gynecological ultrasound to observe the condition of the uterine cavity. If there is residue, the size of the residue and the blood HCG value should be used to determine whether it should be a medicated curettage or a repeat operation. If it is an infection, symptomatic treatment with antibiotics is required. If there is poor uterine regeneration, treatment with contractions and emmenagogue is required.
