The term “great aunt” refers to menstruation. One month after the abortion procedure, if you recover better, your period usually lasts 3 to 7 days; if you do not recover well, the number of days may be lengthened or shortened. After the abortion surgery, if the recovery is better, the duration of menstruation is not different from normal menstruation, which is 3~7 days. However, if the lining of the uterus is damaged during the abortion surgery or if there is not enough nutrition after the abortion surgery, etc., the lining of the uterus may not recover well and the days of menstruation may be shortened or lengthened. If the patient has abnormal menstruation one month after the abortion, it is recommended to consult a doctor in time to improve the relevant examination and carry out standardized treatment for the cause of the disease.
