It's been more than 10 days since my first menstrual period

The menstrual cycle is the period in which menstruation comes to visit you periodically. This cycle is calculated by starting from the first day of your menstrual period to the first day of the next menstrual period. "How many days is a normal menstrual cycle" is a relative definition, which depends on individual circumstances. Under normal circumstances, a normal menstrual cycle is 28 to 30 days, including the menstrual period, mid-term, intermenstrual period and early menstrual period.

How to calculate the menstrual cycle more accurately

The physiological cycle is also called the physiological period or menstrual period. It is generally 28-35 days, and the length of the cycle varies from person to person. When making an estimate, the time of menarche and the time interval between two menstrual periods should be included in the calculation. You can observe carefully and figure it out. The following include the three stages of the physiological cycle. It is more accurate to include them in the statistical analysis during the measurement.

1. Menstrual period: It lasts about 5 days. During this period, the uterine wall, except for the muscle base, bleeds, collapses and falls off. The basic principle is not very clear, but it may be related to the sudden decrease in estrogen and corpus luteum copper metabolism. Each menstrual volume is about 50-200ml, of which about 35ml is blood.

2. Proliferative phase: It lasts about 7-10 days. During this period, under the action of estrogen, the thickness of the uterine wall increases and the proliferation of glandular ducts increases, but there is no metabolism. This period is equivalent to the whole process of the new egg in the uterus and ovaries being perfected. At the end of this period, the uterus and ovaries are completely divided and the egg is released.

3. Metabolic period: about 13-14 days. During this period, the uterine gland duct continues to expand under the action of the corpus luteum copper, becomes tortuous and begins to metabolize, the interstitial space becomes loose and swollen, which is suitable for the implantation of sperm and egg combination. If fertilization has not occurred, the corpus luteum begins to decline, the uterine wall collapses and falls off, and the cycle returns to the first stage.
