What is the normal color of menstrual blood?

When women enter puberty, they begin to menstruate, a physiological phenomenon that accompanies women for most of their lives. Although menstruation can be troublesome, any abnormalities in menstruation can be even more problematic. Normal menstruation is distinguished by its timing, volume, and color, and any issues in these aspects may indicate menstrual problems. So, what is the normal color of menstrual blood? Let's take a look below.

Menstrual blood is a mixture of blood, shed endometrial tissue, cervical mucus, and vaginal secretions. It has a dark color, is slightly viscous, and does not easily clot. Upon closer inspection, there may be small, thin fragments visible. Sometimes, blood clots or dark blood may also appear.

1. Menstrual cycle: The time from the first day of menstruation to the first day of the next menstruation is called a menstrual cycle. Most people have cycles ranging from 28 to 35 days, but some may have shorter cycles of 20 days or longer cycles of 45 days. Within this range, as long as menstruation is regular, it is considered normal.

2. Menstrual period: The time during which vaginal bleeding occurs is called the menstrual period. Most people's menstrual periods last 3-5 days, but durations of 1-2 days or 7-8 days are also within the normal range.

3. Menstrual blood volume: The normal amount of menstrual blood during menstruation is 20-120 milliliters, with most women experiencing around 50 milliliters. The heaviest flow is usually on the second or third day of menstruation, gradually decreasing thereafter.

4. Menstrual blood color: Menstrual blood is characteristically non-coagulable and appears dark red. Besides blood, menstrual blood also contains fragments of shed endometrial tissue, cervical mucus, and vaginal epithelial cells.

5. Cycle: Every woman's menstrual cycle varies, ranging from 21 to 35 days, and is considered normal as long as it is regular. The key is whether it is punctual. Regular sexual activity (e.g., once a week) can help regulate hormones and greatly assist in maintaining a regular menstrual cycle.

6. Blood clots: What are the blood clots expelled during menstruation? Doctors explain that if menstrual blood is obstructed in the same area and not expelled in time, it can accumulate for 5-10 minutes and form blood clots. Blood clots usually occur in the morning after waking up or after sitting for a long time.

7. Amenorrhea: The first step in addressing amenorrhea (absence of menstruation) is to rule out pregnancy. If pregnancy is not the cause, then it is necessary to examine your lifestyle: factors such as travel, stress, intense exercise, excessive weight loss, and climate changes can all affect the menstrual cycle. Hormonal and thyroid imbalances can also lead to extended menstrual cycles.
