How many days is a normal menstrual cycle

Generally, a menstrual cycle of 21 to 35 days is normal, and you only need to do relevant care during this period.

Generally speaking, the menstrual cycle is 21 to 35 days, which is a normal phenomenon. The menstrual cycle is calculated from the first day of this menstruation to the first day of the next menstruation. On average, a woman's menstrual cycle is about 28 days, but it may fluctuate due to factors such as diet, living environment, and emotions. However, as long as the menstrual cycle is within this normal range and maintains a certain regularity, it is a normal physiological phenomenon.

The regularity of a woman's menstrual cycle is regulated by hormone levels in the body, and these hormones are also affected by a variety of factors such as diet, mood, and environment. Maintaining a healthy lifestyle, eating habits, and a good mood can help maintain a normal menstrual cycle.

If a woman's menstrual cycle is shorter than 21 days or longer than 35 days for a long time, and is accompanied by abnormal bleeding, pain and other discomfort symptoms, she needs to seek medical attention in time and seek help from a professional doctor.

Note:

You should pay more attention to personal hygiene, take a bath and change clothes frequently. You should have a reasonable diet and avoid being picky or partial.
