When is the safe period of menstruation? The birth of a new life begins with the fusion of sperm and egg cells. In order to achieve the actual effect of contraceptive measures, we must try our best to prevent their coming together. The strategy of safe period contraception is to calculate the appearance time of the egg cell and the possible fertilization time, and let the sperm avoid these times and go out to act. When is the safe menstrual period? From the perspective of contraception, 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 1-2 days after being released, and the sperm can survive in the female reproductive system for 2-3 days. The fertilization ability is mostly within 24 hours after ovulation. After 2-3 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 10 days before and after the ovulation period the ovulation period, and the rest of the menstrual cycle 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. A few days before and after menstruation is the safe menstrual period The safe menstrual period refers to the period from the end of the previous ovulation period to the next ovulation period. Generally speaking, if a woman has a normal menstrual cycle of 28 days, the period from seven days before the first day of menarche to eight days after the first day of menarche is 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. This is because some women are sometimes affected by environmental damage and mood swings, which cause ovulation to be advanced, thus shortening the safe menstrual period before ovulation. Seven days before menstruation and eight days after menstruation are the safe menstrual period for adult women, which is a calculation method used by most people for contraceptive measures. In addition to the calendar method using the number of days to calculate, there is also the ovulation temperature method and secretion observation. However, the safe menstruation period is not absolutely safe. Sometimes women ovulate earlier or later, so the judgment of the safe menstruation period will become invalid. |
