Irregular menstruation comes 2 times a month, if it is 1 time more and 1 time less, and the 2nd time mostly occurs during ovulation, the menstrual volume is relatively small, it clears in 2-3 days, and there is no discomfort, most of them belong to ovulatory bleeding. If it occurs 1-2 times occasionally, no special treatment is needed, it is mainly related to the transient decrease of estrogen during ovulation. If it occurs 3 or more times in a row, tests must be done to rule out endometrial polyps, cervical or endometrial neoplastic lesions. If it is determined that the bleeding is purely ovulatory, it can be regulated with medication and is usually treated with contraceptive pills of choice. If it is not ovulatory bleeding but other causes of menstrual disorders, it must be treated specifically for the cause. To find the cause most gynecological examinations should be done. When bleeding do be able to see where the blood actually comes from, which part of the bleeding, find out the part and then for the bleeding part, find the cause of the right treatment.
