Which day of menstruation is the safe period?

For those who want to use safe period to prevent pregnancy, they would like to know which day of menstruation is the safe period, so that they can effectively prevent pregnancy. So which day of menstruation is the safe period? I believe many friends want to know the answer to this question. Next, this article will introduce to you the relevant content about which day of menstruation is the safe period, for your reference only. Please see the detailed introduction below.

Normal women of childbearing age have menstruation once every 28 days or so. The period from the beginning of one 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.

Which day of menstruation is 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 three days 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. Generally speaking, the safe period refers to the 7 days before and 8 days after a woman's menstruation.

Generally speaking, 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.

The key to using safe period contraception is to determine the female ovulation date. When the ovaries ovulate, 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 phenomena are not specific symptoms of ovulation and therefore cannot be used as a basis for ovulation. Menstruation and ovulation change cyclically, and there is a close relationship between the two. If you understand the changing patterns of the two, you can determine the ovulation date through indirect methods. There are many ways to determine the ovulation date, and the methods that women can master themselves include: calculating based on the menstrual cycle, measuring basal body temperature, and observing cervical mucus secretion.

The safe period contraceptive method 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 mastered or used improperly, it can easily lead to failure. According to statistics from relevant foreign experts, the failure rate of safe period contraception is as high as 14.4% to 47%. This method is only suitable for people who have normal menstrual cycles, live together for a long time, and can correctly calculate the safe period.

The high failure rate of safe period contraception is mainly related to the following two factors:

1. Since the time of female ovulation is affected by factors such as the external environment, climate, one's own emotions, health status and physical condition, ovulation may be delayed or advanced, and extra ovulation may also occur, that is, ovulation twice in a month. This is one of the reasons for the high failure rate.

2. Since hormones in the body can also induce ovulation, when two people have sex, if they are particularly excited, it will increase hormone secretion, which may lead to ovulation. Therefore, this is also one of the important reasons leading to failure.

The above is the introduction about which day of menstruation is the safe period. I believe that after reading the above introduction, you already know which day of menstruation is the safe period. Generally speaking, the first 7 days of menstruation and the last 8 days of menstruation are the safe period! However, contraception during the safe period is not necessarily safe! Therefore, it is better for everyone to learn some more effective contraceptive methods!
