How to calculate menstrual period for girls

Women must pay attention to their diet during their menstrual period. They cannot eat some cold foods at this time, otherwise it will cause dysmenorrhea. At the same time, for some women who already have dysmenorrhea, such foods should not be chosen. So what is the method to calculate the menstrual period for girls? Many women don’t know much about this. The following is a detailed introduction so that you can have some understanding of the method to calculate the menstrual period for girls.

How to calculate the menstrual period for girls:

The first day of bleeding is the beginning of the menstrual cycle, and the interval between the first days of two menstruations is called the menstrual cycle. Therefore, the calculation of the menstrual cycle should include the time of menstruation. Some women only count the time when their menstruation stops, so they may think that their menstrual cycle is shortened. Clinically, some women often complain of irregular menstruation, with two periods in a month. In fact, if you calculate carefully, it is normal to have a menstrual period once at the beginning and end of the month. The normal menstrual cycle is 28-35 days. The length of the cycle may vary from person to person. 7-10 days early or late can be considered within the normal range. As long as a certain regularity can be maintained, it cannot be considered as irregular menstruation.

The last menstrual period refers to the menstrual period closest to the date of consultation and should be calculated from the first day of bleeding. However, it should be noted that the last menstrual period refers to the duration and amount of this menstrual period that are the same as usual. Do not mistake abnormal vaginal bleeding for menstruation. This type of bleeding is generally less than menstrual period, and the duration may be shorter or longer, or the normal menstrual pattern may be lost.

The duration of menstruation is generally 3-7 days, and the amount of bleeding is within 20-60 ml, with the highest amount on the 2nd or 3rd day. Menstrual blood is generally dark red and does not coagulate. In addition to blood, it also contains endometrial fragments, cervical mucus and vaginal epithelial cells. Generally, women have no symptoms during menstruation. A few may experience discomfort such as a feeling of heaviness in the lower abdomen or lumbar region, breast tenderness, constipation or diarrhea, and headache, which generally do not affect their daily work, study, and life.

After understanding the method of calculating girls' menstrual period, you can follow the above method when calculating girls' menstrual period. However, there are some abnormal times when women's menstrual period occurs. For example, excessive fatigue of the female body can cause early or delayed menstruation. This phenomenon will not have much impact on the female body, and women should also pay attention to this.
