How to know when ovulation occurs

Ovulation and menstruation are closely related. Regarding changes in ovulation, we should also pay attention to changes in menstruation.

The ovulation period normally lasts for 3 to 5 days. The chance of conception during the ovulation period is the highest.

When is ovulation?

Ovulation is closely related to menstruation, so when are the ovulation days? Many friends are still not very clear about when the ovulation period is, but if you don’t know how many days the ovulation period is, it will be difficult to grasp the time for 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 generally about 14 days before the next menstrual period. The 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days are called the ovulation period.

2. If your menstrual period is unstable, 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 take the first day of menstruation as the base point and count the days backwards.

For example, if 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 means that there is a possibility of ovulation during this period, and it is impossible to accurately calculate the exact day of ovulation.

How many days after menstruation is ovulation

Since everyone's menstrual cycle is different, the answer to how many days after menstruation is the ovulation period will also be different. However, you can calculate the ovulation period according to this formula:

1. For women with relatively stable menstrual periods: the ovulation day is generally the 14th day before the next menstrual period. The 5 days before this day, including this day and the 4 days after this day, are called the ovulation period. In other words, the ovulation period of an average woman is ten days.

2. If the menstrual cycle is unstable, the ovulation period can be calculated in this way: 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 take the first day of menstruation as the base point and count the days backwards.
