Is the period before the period safe?

Menstruation is a normal physiological cycle for women and is also a good friend of women every month. In addition to menstruation, many women should also pay attention to their safe period and ovulation period every month and make reasonable calculations. It is not ruled out that the period before menstruation may be a safe period, and pregnancy may occur during the non-ovulation period. This situation requires special attention.

Is the period before the period safe?

Normal women of childbearing age have menstruation once a month. From the beginning of this menstruation to the first day of the next menstruation, it is called a menstrual cycle. From the perspective of contraception, each menstrual cycle of women can be divided into 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. Before the advent of contraceptive pills and intrauterine devices, it was one of the commonly used contraceptive methods at home and abroad.

Women usually ovulate about 14 days before the next menstrual period. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days to wait for fertilization. The male sperm can maintain fertilization ability in the female reproductive tract for 2-3 days. Therefore, it is easy to get pregnant by having sex a few days before and after the egg is released. To be on the safe side, we call the 5 days before and 4 days after ovulation, including the ovulation day, a total of 10 days, the ovulation period. Because it is easy to get pregnant by having sex during the ovulation period, the ovulation period is also called the easy-to-get pregnant period or the dangerous period.

The safety period is divided into the safe period before ovulation and the safe period after ovulation. The period from the day when menstruation is over 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 cramp is the safe period after ovulation. The safe period after ovulation is safer than the safe period before ovulation. This is because some women are sometimes affected by environmental changes and mood swings to ovulate in advance. In this way, the safe period before ovulation will be shortened. And I don't know it. In this way, the safe period before ovulation is not very safe. The opportunity of the ovary to ovulate twice in a menstrual cycle is very rare. That is, the second ovulation will not happen again during this period from ovulation to the next menstrual cramp. Therefore, the safe period after ovulation is relatively safe.
