When is menstruation? When is ovulation?

Menstruation refers to a woman’s regular vaginal bleeding every month, which usually lasts for about 3-7 days. The date of a woman's menstrual period can be affected by a variety of factors, such as genetics, hormonal changes, diet and lifestyle. Generally speaking, a woman's menstrual cycle is about 28 days, but some people may have it a few days earlier or later.

So, when is ovulation? In fact, women’s menstrual cycle and ovarian cycle are closely related. The ovary is an important organ in the female reproductive system. It releases a mature egg every month. After the egg is released, it needs to wait 24-72 hours in the body before fertilization. Therefore, during a woman's menstrual cycle, the ovarian cycle is fixed, and the ovulation period is determined based on the ovarian cycle.

Generally speaking, in a woman's menstrual cycle, the ovarian cycle lasts for 28 days, but some people may have it a few days earlier or later. Within a few days after the ovarian cycle ends, that is, on days 14-19 of a woman's menstrual cycle, it is the woman's ovulation period. At this time, a woman's vaginal discharge will increase in volume, become darker in color, become thicker in texture, and may contain a small amount of sperm.
