Safe menstrual period calculator

Safe menstrual period calculator

The safe period calculation refers to the menstrual period that normal women of childbearing age have once a month. From the beginning of this menstruation to the first day of the next menstruation, it is called a physiological cycle. So what is the calculation method for the safe menstrual period?

For example, from the perspective of contraception, each menstrual cycle of a woman can be divided into menstrual period, ovulation period and safe menstrual period. Safe period contraception is a contraceptive measure that terminates sexual intercourse during the ovulation period. It is a traditional contraceptive measure and was one of the common contraceptive measures in countries around the world before the advent of emergency contraception and IUDs.

Safe menstrual period

Women's ovulation period is generally about 14 days before the next menstrual period. After the egg cell is discharged from the uterus and ovary, it can survive in the fallopian tubes for 1-2 days to wait for fertilization; the male sperm can remain active for 2-3 days in the female reproductive system, so it is very easy to get pregnant by having sex a few days before and after the egg cell is discharged. To be on the safe side, we call the 5 days before and 4 days after ovulation, a total of 10 days within the ovulation period, the ovulation period. Since it is very easy to get pregnant during sexual intercourse during the ovulation period, the ovulation period is also called the fertile period or the dangerous period of pregnancy.

The safe menstrual period is divided into the safe menstrual period before ovulation and the safe menstrual period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after ovulation to the day before the next menstrual period is the safe period after ovulation. Generally speaking, the safe menstruation period after ovulation is safer than the safe menstruation period before ovulation. This is because some women sometimes affected by environmental damage and mood swings affect the advance of ovulation, so before ovulation safe period will be shortened, but they do not know, so before ovulation safety period is not safe. The ovaries in one menstrual cycle have two eggs in a row opportunity is very rare, that is, after ovulation until the next menstrual menarche before this period of time usually won't happen again the second time of ovulation, so the menstrual safety period after ovulation is relatively safe.

The key to choosing safe period contraception is to measure the time of women's ovulation. During the ovulation period, there is generally no special feeling. Even though some women may have symptoms such as lower abdominal pain, back pain, breast swelling and mood changes, these symptoms are not unique to the ovulation period and cannot be used as a basis for ovulation. Menstrual period and ovulation period change regularly and are closely related to each other. If you understand the changing trends of the two, you can measure the ovulation time indirectly. There are many ways to measure the time of ovulation, and the methods that women can master themselves include: calculating according to the menstrual cycle, accurately measuring the ovulation temperature, and observing the secretion of cervical mucus.

From the perspective of contraceptive measures, each menstrual cycle of a woman can be divided into menstrual period, ovulation period and safe menstrual period. Generally speaking, the ovaries of women of normal childbearing age only release one egg cell per month. The egg cell can survive for 1 to 2 days after being released, and the sperm can survive for 2 to 3 days in the female reproductive system. The fertilization ability is mostly within 24 hours after ovulation. After 2 to 3 days, the sperm will lose the ability to fuse with the egg cell. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may become pregnant. This stage is called the fertile period or the dangerous period of pregnancy.

Women's ovulation period is generally about 14 days before the next menstrual period. To be on the safe side, we call the 5 days before and 4 days after ovulation the total of 10 days in the ovulation period. The other time outside the menstrual period is called the safe menstrual period. The safe menstrual period is divided into the safe menstrual period before ovulation and the safe menstrual period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after ovulation to the day before the next menstrual period is the safe period after ovulation. The safe menstruation period after ovulation is safer than the safe menstruation period before ovulation.
