If you have vaginal bleeding twice a month, only one time is physiological menstruation and the other time is abnormal bleeding. If irregular bleeding occurs in the middle of menstruation, it is often caused by ovulatory bleeding. It is recommended that you can take oral Glaxo on the 12th day of menstruation and take half a tablet once a day for 7 days to effectively treat ovulatory bleeding. Secondly, if irregular vaginal bleeding occurs during the first half of the menstrual period, it is often caused by estrogen deficiency and can be treated clinically with estrogen supplementation. Again, if the irregular vaginal bleeding occurs during the second half of the menstrual period, it is often due to progesterone deficiency and can be treated with oral progesterone. In either case, it is recommended to have a blood test on the second day of menstruation to check the sex hormone count, and according to the result, to give the treatment, or to have an ultrasound to exclude the possibility of organic lesions of the uterus.
