Safe period and ovulation period calculator

Many people use contraceptive measures based on calculating the safe period and ovulation period, but this contraceptive measure has certain risks, which has also caused many people to become pregnant out of wedlock. The safe menstrual period is not absolutely safe, so when is the safe menstrual period and ovulation period?

Except for the ovulation period and menstrual period, the remaining time is called the safe menstrual period. Women's safe menstruation period can be further divided into the safe menstruation period after ovulation and the safe menstruation period before ovulation. From the first day after the end of a woman's ovulation period, until the day before the next menstrual period is called the safe menstrual period after ovulation. From the day after the end of the menstrual cycle to the day before ovulation, this entire period is called the safe menstrual period before ovulation.

Generally speaking, women's ovulation period is mostly about fourteen days before the next menstrual period. After careful consideration, the four days after ovulation and the five days before ovulation are generally added to the ovulation period, a total of ten days is called the ovulation period.

The menstrual ovulation calculation method is an APP that is widely available on every website or downloaded for free on mobile phones. There are two different versions of the calculation method for menstrual ovulation period. One is the online calculation method used on each web page. The calculation method stored on the web page can be estimated online. Another version is the mobile phone APP client software, which can be downloaded and installed, and can also be downloaded to the computer, which will be more convenient to use.

So how do you calculate the safe period?

Taking the 28-day menstrual cycle as an example, 3 to 5 days after the first menstruation comes, it can be said that the "menstrual period" begins, and the first stage of the menstrual safety period begins after cleansing. The two safe menstrual periods in the middle of the menstrual cycle are separated by the ovulation period. The ovulation period can almost be confirmed on the 14th day before the next menstrual period, or 5 days earlier or 4 days later. This is also known as the dangerous period of pregnancy. Since male sperm can survive in the female body for 3 days, it is necessary to move the safe period of pregnancy from 5 days within the above 14 days to 3 days in advance in case of an emergency. That day is the end of the first stage of the safe menstrual period. The second stage of the safe menstrual period begins 4 days after the above situation 14 days, until the second menstrual period arrives. This shows that the second stage of the menstrual safety period is safer than the first stage. Generally, ovulation occurs 12 to 22 days after menstruation, marking the dangerous period of pregnancy.
