How many days is a normal menstrual period?

Menstruation is a normal physiological phenomenon when every girl ovulates. Therefore, many girls do not know how many days a normal menstrual period lasts. In order to avoid problems, patients do not know this knowledge. So how many days is a normal menstrual period? Let us ask an expert to introduce this issue to us.

In medicine, the first day of menstrual bleeding is generally counted as the beginning of the menstrual cycle, and the menstrual period is generally 3-7 days. The interval between the first days of two menstrual periods is one menstrual cycle. A shortening or extension of about 7 days is still considered a normal menstrual cycle. A normal, stable menstrual cycle is 28-30 days. However, due to the influence of race, genetics, and internal and external environment, there are individual differences, generally ranging from 21 to 35 days. In addition, some people may have their period a week earlier or later due to internal and external environmental factors, which is all normal. For girls who have just reached menarche, irregular menstrual cycles are a normal physiological phenomenon and will generally return to normal within a year.

Generally speaking, as long as a person's menstruation is regular, whether it is 21 days or 35 days, it is considered a normal menstrual cycle. An occasional delay in menstruation is not necessarily a sign of disease. If your menstrual cycle is normal, but your period is delayed for more than 7 days for more than two or three consecutive cycles, you should consider seeing a doctor.

Whether menstruation is normal or not is not only determined by the duration of menstruation, but also by the menstrual cycle, menstrual blood volume, etc. The duration of menstruation is generally 3-7 days, with an average of 5 days. The length of the cycle varies from person to person, ranging from about 21-36 days, with an average of about 28 days. The average amount of bleeding is about 50 ml, but can be as little as 20 ml or as much as 100 ml. You can refer to it.

The above is the expert’s opinion on this issue. The menstrual period generally occurs during the above-mentioned time period, so there is no need to worry too much or too little. Consult an expert to check whether there are other conditions that affect the patient’s health, ensure the patient’s safety and health, and finally wish the patient a speedy recovery.
