When is ovulation?

The ovulation period is closely related to the menstrual period, so when are the ovulation days? Many friends are still not very clear about when the ovulation period is, but if everyone does not know when the ovulation period is, it will be difficult to grasp the time of having sex. Let’s find out when ovulation occurs!

When is ovulation?

1. If the menstrual cycle is regular, a woman's ovulation period is usually about 14 days before the next menarche. The 5 days before and 4 days after ovulation, a total of 10 days within the ovulation period, are called the ovulation period.

2. If your menstrual period is unstable, then your ovulation period can be calculated as follows: the first day of ovulation = the shortest menstrual cycle minus 18 days, the last day of ovulation = the longest menstrual cycle minus 11 days. The calculation method is to use the first day of menarche as the reference point and count the days backwards.

For example, your menstrual cycle is irregular, sometimes it is only 23 days, and sometimes it is as long as 35 days. Then the first day of your ovulation period is 23-18=5, and the last day of your ovulation period is 35-11=24. In this case, the ovulation period may be as long as 24-5=19 days. However, this only indicates the possibility of ovulation during this period, and it is impossible to accurately calculate the exact day of ovulation.

How many days does ovulation occur?

How many days does ovulation occur? Generally speaking, women's ovulation period is 10 days, but mentality, diet, lifestyle, environment and other factors will affect the ovulation period, so the number of days of ovulation varies from person to person.

1. Generally speaking, women's ovulation period is 10 days.

A normal woman will ovulate once in every menstrual cycle (usually one month). The day of ovulation is called the "ovulation period". The 5 days before ovulation, the 4 days after ovulation, plus the day of ovulation are the woman's ovulation period. Therefore, girls' ovulation period is 10 days.

2. Not everyone’s ovulation period is 10 days.

As the pace of modern life continues to accelerate, women are increasingly affected by the physical environment. In addition, women's mentality, diet, and lifestyle all affect their ovulation period. When a woman with a relatively regular rhythm of life suddenly changes her daily routine, if the body does not adjust in time, the endocrine state may be affected, and the menstrual period may be advanced or delayed. Then the length of the ovulation period will fluctuate with the change of the menstrual period. Therefore, the ovulation period of 10 days is only an approximate time period, and in fact, the ovulation period of women is generally less than 10 days.

3. The reasonable pregnancy time during the ovulation period is 7 days.

Since the ovulation period is not necessarily a fixed ten days, then how long is the effective pregnancy time during the ovulation period? Generally speaking, the survival time of a normal woman's egg cell is about 2 days, as short as 3 days, and as short as less than 12 hours. A man's sperm can usually survive in a woman's body for 3 to 5 days, usually 4 days.

In other words, the effective pregnancy time during the ovulation period is generally 5 days before the girl's ovulation, because the sperm can survive in the woman's body for up to 5 days, and 2 days after the girl's ovulation, because the egg can only survive in the woman's body for 2 days after it is released. In other words, the effective pregnancy time is generally about 7 days.
