The menstrual cycle refers to the period from the first day of your menstrual period to the next menstrual period. In other words, it is the "menstrual process" every month. Most people have a menstrual cycle of 28 days, but everyone is different.
Normal range: Most girls have a menstrual cycle of about 28 days, that is, from the first day of a menstrual period to the first day of the next menstrual period, which is about 28 days.
Short or long is normal: Some girls may have a slightly shorter cycle, 21 days is also common; some may be longer, 35 days is no problem. As long as it is not particularly irregular, it is basically within the normal range.
The duration of menstruation is usually 3 to 7 days. This is also a normal range. Some people have only 4 or 5 days of menstruation, while others may have more, and 7 days is also common.
At the beginning of menstruation, the flow may be more, and in the last few days, the flow will gradually decrease and basically end.
The menstrual cycle may change due to some factors, such as:
When you first start menstruating: When you first start menstruating, the cycle may be irregular, and the duration is not certain. After a period of time, it will become more regular.
Stress, fatigue, unhealthy diet: If you are under a lot of stress or have an irregular schedule, your menstrual cycle may also change.
Pregnancy, breastfeeding: If you are pregnant, your menstruation will stop, and breastfeeding mothers may also stop menstruating for a period of time.
Older age: With age, especially after entering 40 years old, the menstrual cycle may become irregular.
Regular menstrual cycle: If your menstruation comes roughly once a month, the cycle is similar, and the flow is not too much or too little, then your menstruation is normal.
Abnormal symptoms: If your menstrual cycle suddenly becomes very long or very short, or your period lasts for more than 7 days, your flow is particularly heavy or light, or your period suddenly stops for a long time, you should see a doctor as this may be a bit abnormal.
