It is not normal to have a period once every two months. You need to go to the obstetrics and gynecology department of the hospital for examination in time to clarify the cause and take appropriate measures. The normal menstrual cycle is about 28 days, and a week early and a week late are normal physiological phenomena. If you have menstruation once in two months, i.e. 60 days a cycle is prolonged menstruation. It may be caused by abnormal thickening of the endometrium, or endometrial polyps, endometritis and other lesions, and hysteroscopy is recommended, and scraping may be required if necessary. Also for patients with cervical adhesions and cervical adhesions, they can cause poor flow of menstrual blood, which in turn leads to prolonged periods and requires surgical treatment with uterine separation.

It needs to be treated accordingly according to the different causes. In addition, it is important to keep warm, avoid cold, spicy and stimulating food, pay attention to rest and avoid strenuous exercise.
