Understanding your menstrual cycle is important to taking control of a woman's fertility and reproductive health. Generally speaking, a woman's menstrual cycle lasts 28 days, but it varies from person to person. Some women may find that their menstrual cycles are 30 or 32 days, while others may find that their cycles are 21 or 25 days. Regardless of cycle length, every woman has her own unique cycle.

So, when does a woman’s menstrual cycle end? Generally, when a woman's menstrual cycle ends depends on the number of days in their cycle and the amount of bleeding. For women with a 28-day cycle, the cycle ends on the 3rd of each month. For women with 30-day or 32-day cycles, the cycle ends on the 15th of each month.

So, when is ovulation in a woman’s menstrual cycle? Generally speaking, in a woman’s menstrual cycle, ovulation occurs from the 17th to the 23rd of each month. During ovulation, the female body produces a large number of eggs, which wait for fertilization and then become the basis for embryonic development. Therefore, understanding a woman’s menstrual cycle and ovulation is very important for women’s reproductive health.

In addition to understanding a woman's menstrual cycle and ovulation, there are other ways to learn about women's reproductive health. For example, women can understand their reproductive health status by measuring body temperature, observing vaginal bleeding, and conducting B-ultrasound examinations. At the same time, women can also improve their reproductive health through healthy lifestyles, such as maintaining a healthy lifestyle, reducing stress, and avoiding smoking and drinking.
