Bleeding two months after cervical ligation is not normal. The cervix will bleed a small amount just after ligation, and vaginal bleeding two months after ligation is considered to have the possibility of pre-eclampsia, or it may be a tumor disease. 1. Pre-eclampsia: Cervical cerclage is suitable for pregnant women whose cervical opening is loose and prone to miscarriage, and it is best to carry out the operation during the period of 14 to 18 weeks. Vaginal bleeding two months after the operation is likely to be pre-eclampsia, which can be accompanied by mild pain in the lower abdomen, and the amount of bleeding is relatively small, and it is necessary to use fertility preservation medicines such as dieldieldieldenone, etc., and it is necessary to carry out the operation of abortion if the fertility preservation is ineffective. 2. Placenta praevia: If the placenta of a pregnant woman is not attached to the anterior, posterior or lateral wall of the uterine body, but the lower edge of the placenta is close to the cervical os, it is called placenta praevia, which has the possibility of spontaneous abortion, such as vigorous exercise, squatting, etc., which can induce bleeding and abortion, and it should be actively preserved, and if it is difficult to avoid miscarriage, it is necessary to remove the sutures, and wait for the birth of the fetus, and clear the uterus if necessary. 3. Cervical polyps: the disease is due to the cervix localized chronic inflammation stimulation, resulting in tissue hyperplasia to form redundant organisms, usually a small amount of vaginal bleeding symptoms, or vaginal secretions mixed with blood, which belongs to a benign lesion, pregnancy can not be dealt with for the time being. It is recommended that patients go to the gynecology department in time for further examination to clarify the cause of bleeding, and do not blindly use medication on their own.
