Many women are rather casual in their diet during menstruation, which is not helpful to their bodies. Casual eating can easily cause physical illness, the most common of which is abdominal pain.

Is a 21-day menstrual cycle normal?

The periodic vaginal bleeding that occurs in women is called menstruation. Whether a woman's menstruation is normal can generally be judged from the following aspects.

Menstrual cycle: From the first day of menstruation to the first day of the next menstruation is called a menstrual cycle. For the vast majority of people, the menstrual cycle is between 28-35 days, but for a few, it can be as short as 20 days or as long as 45 days. Within the above range, as long as the menstruation is regular, it is normal.

Menstrual period: The period of vaginal bleeding is called the menstrual period. Most people's menstrual period lasts 3-5 days, but as little as 1-2 days and as much as 7-8 days is also within the normal range.

Menstrual blood volume: The menstrual blood volume during normal menstruation is 20-120 ml, most of which is 50 ml. It is highest on the second or third day of menstruation and gradually decreases afterwards.

Characteristics of menstrual blood: Menstrual blood is characterized by non-coagulation and dark red color. In addition to blood, menstrual blood also contains fragments of endometrial lining, cervical mucus and vaginal epithelial cells.

Menstruation is a normal physiological phenomenon for women. Most women have no obvious symptoms during menstruation, but a few women may experience breast swelling, headache, insomnia, palpitations, lower abdominal distension and pain, and emotional instability. This situation generally does not affect work and does not require treatment. The symptoms will disappear naturally after the menstrual period. Normal menstruation is a manifestation of normal development and sound function of female internal reproductive organs.

After understanding whether a 21-day menstrual cycle is normal, there is no need to worry about such problems. The menstrual cycle is different depending on the physical constitution of women. If there are two menstrual periods in a month, the body needs to be adjusted, otherwise it is easy to cause diseases. Women should pay attention to this.
