Is the safe period a few days before menstruation?

In the life of both sexes, the most important thing that everyone is concerned about is the issue of contraception. There are many contraceptive methods available for everyone to choose in daily life. Safe period contraception is a very common contraceptive method, but safe period contraception is very unsafe. Safe period contraception first requires you to figure out your safe period. Many women don’t know their safe period. In general, are the days before menstruation unsafe?

Is the safe period a few days before the period?

The safe period is divided into the safe period before ovulation and the safe 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 the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation. The safe period after ovulation is safer than the safe period before ovulation. This is because some women sometimes affected by environmental changes and mood swings affect the advance of the ovulation, so before the safe period ovulation will be shortened, but did not know their own, so before the safety period ovulation is not safe. The opportunity that the ovary has row two eggs in a menstrual cycle is very rare, that is, after ovulation to the next menstrual cramps before this period of time usually won't happen again the second time of ovulation, so the safety period after ovulation is relatively safe.

Calculate ovulation based on menstrual cycle

The method of calculating ovulation according to the menstrual cycle is also called the calendar method. Both menstruation and ovulation are affected by endocrine hormones from the pituitary gland and ovaries and show cyclical changes. The length of their cycles is the same, both occurring once a month, and ovulation occurs between two menstrual periods. Women's menstrual cycles vary in length, but the interval between ovulation and the start of the next menstruation is relatively fixed, usually around 14 days.

Based on this relationship between ovulation and menstruation, the ovulation period can be calculated according to the menstrual cycle. The calculation method is to count from the first day of the next menstrual period, and count down 14 days or subtract 14 days to get the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation day are called the ovulation period. This is the theoretical basis of the rhythm method of contraception. For example, a woman's menstrual cycle is 28 days, and the first day of this menstruation is December 2nd. Then the next menstruation will be on December 30th (December 2nd plus 28 days). Subtract 14 days from December 30th, and December 16th is the ovulation day. The ovulation day and the 5 days before and 4 days after it, that is, December 11-20, is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe period. There is no need to use any contraceptive drugs or tools during sexual intercourse during the safe period.

Normal women of childbearing age have menstruation once a month. The period from the beginning of this menstruation to the first day of the next menstruation is called a menstrual cycle. For example, from the perspective of contraception, each menstrual cycle of a woman can be divided into the menstrual period, ovulation period and safe period. Safe period contraception is a contraceptive method that stops sexual intercourse during the ovulation period. This is a traditional contraceptive method and was one of the commonly used contraceptive methods at home and abroad before the advent of birth control pills and intrauterine devices.
