How many days before and after menstruation is the safe period

Young people nowadays don’t like to use contraceptive measures, but if they don’t, there is a possibility of accidental pregnancy. If you don't like to use contraceptives, you can calculate the safe physiological period for girls. If a woman's menstrual period is stable, the safe period is also a better choice. How many days before and after the menstrual period are the safe period? The following will teach you in detail how to calculate your own safe physiological period.

1. How many days after menstruation is the safe period

Generally speaking, the 7 days after menstruation is the safe period. The menstrual cycle is generally 28 days, calculated from the first day of menstruation to the day before the second menstruation. The ovulation period is in the middle of the menstrual cycle, which is the 14th day. If the egg is not fertilized, it can survive for 2 days, that is, on the 14th, 15th and 16th days. The survival time of sperm after entering the female reproductive organ is 3 days, and the rest of the time is the safe period. To be on the safe side (ovulation is advanced or delayed), push it back 5 days, so that the 7 days after menstruation is the safe period.

In addition, by observing the changes in vaginal secretions, you can also calculate the number of days after menstruation that are the safe period. Women's vaginal secretions change objectively with the contrasting dates of the menstrual cycle. During ovulation, the mucus becomes more and more, the vagina feels moist, the mucus becomes clear, and the mucus can be stretched into threads, which can be up to 10 cm long. The last day that this mucus lasts is usually the ovulation period, and no sexual intercourse is allowed 3-4 days before and 5-7 days after ovulation.

The safe period refers to a contraceptive method that calculates the ovulation period through various calculation methods and stops sexual intercourse during the ovulation period. It is normal for women to have a menstrual cycle of 26 to 35 days, and many women ovulate earlier or later, at which time the judgment of the safe period becomes invalid.

Commonly used methods for calculating the safe period include the calendar method, basal body temperature measurement method, vaginal secretion observation method, ovulation tester monitoring method, etc. Only by combining the above safe period calculation methods can the contraceptive effect be effectively improved.

2. When is the safe period?

From the perspective of contraception, each menstrual cycle of a woman can be divided into the menstrual period, ovulation period and safe period. Generally speaking, the ovaries of women of normal childbearing age release only one egg per month. The egg can survive for 1-2 days after being released, and the sperm can survive in the female reproductive tract for 2-3 days. The fertilization ability is mostly within 24 hours after ovulation. After 2-3 days, the sperm loses the ability to combine with the egg. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may get pregnant. This period is called the fertile period or the dangerous period. A woman's ovulation date is generally about 14 days before the next menstrual period.

To be on the safe side, we call the 10 days including the 5 days before and 4 days after ovulation the ovulation period, and the rest of the time outside the menstrual cycle the safe 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.

Safe period contraception is a physiological contraceptive method. Sexual life is carried out under normal conditions and satisfactory sexual pleasure can be obtained. However, if it is not strictly controlled or used improperly, it can easily lead to failure.
