Except for the menstrual and ovulation periods of women, the rest of the time is a safe period. If sexual activity is carried out during the safe period, pregnancy is generally not possible, which is also a concern for many young men and women who do not want to take contraceptive measures. However, some people do not know when the safe period is. In order to avoid pregnancy as much as possible, it is necessary to master precise methods, as this directly affects women's physical and mental health.
The ovulation period for women is generally around 14 days before the next menstrual period. For safety reasons, we refer to the first 5 days and last 4 days of ovulation, including ovulation day, as the ovulation period, which lasts for a total of 10 days. Generally speaking, women of normal reproductive age only release one egg per month from their ovaries. After the egg is released, it can survive for 1-2 days, and sperm can survive in the female reproductive tract for 2-3 days. Fertilization ability is mostly within 24 hours after ovulation, and after 2-3 days, sperm lose the ability to bind with the egg. Therefore, having sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation is possible to conceive, and this period is called the easy pregnancy or dangerous period.
How is the safe period for women calculated? The safe period of menstruation refers to the period from the end of the last ovulation period to the next ovulation period. Generally speaking, if a woman has a normal menstrual cycle of 28 days, the period of seven days before and eight days after the first day of menstruation is the safe period, commonly known as the "seven days before and eight days after". The seven days before and eight days after menstruation are the safe periods for adult women and are a calculation method used by most people for contraception. In addition to using the calendar method of calculating days, the safe period for women can also be calculated through the basal body temperature method and secretion observation method. However, the safe period for contraception is not absolutely safe. Sometimes women ovulate earlier or later, and the determination of the safe period becomes invalid.
Based on the above introduction, we should now know when the safe period is. Many people may know about the first seven and last eight safe periods, which mainly refer to the period from the end of ovulation to the next ovulation. This is also directly related to a woman's menstrual cycle and ovulation period. If her menstrual cycle is normal, then the safe period is generally more regular.
