Three tips for calculating the safe period for women to help you calculate the safe period

　　The days in a menstrual cycle other than the ovulation period can be calculated as the safe period, and the ovulation period is generally about fourteen days before the first day of the next menstrual period. Except for the menstrual period and ovulation period, the rest of the time are safe periods. in How to calculate safety period There are the following types:

　　1. Body temperature method

　　The body temperature begins to rise one to two days after ovulation, and is about 0.2 to 0.4 higher than before ovulation. Therefore, measuring the body temperature after waking up every morning but before getting up can also help to calculate the safe period.

　　2. Billings method

　　Generally, when a large amount of lubricating mucus appears in adult women, it is close to the ovulation period. At this time, the vaginal secretions are clearer and can be pulled out of filaments without breaking easily. During the safe period, vaginal secretions are sparse and thick, and tend to break when drawing.

　　3. Time method

　　The menstrual cycle starts from the first day of menstruation to the day before the next menstrual period. Ovulation generally occurs in the middle of the menstrual cycle. Calculated with a cycle of 28 days, the ovulation period should be about 14 days before the next menstrual period. Theoretically speaking, it is easier to get pregnant in the two or three days before and after ovulation, and the rest of the time is considered a safe period.

　　What is the female safe period?

　　What is the female safe period ? From the perspective of contraception, each menstrual cycle of a woman can be divided into menstrual period, ovulation period and safe period.

　　Generally speaking, the ovaries of women of normal reproductive age only release one egg per month. Eggs can survive for 1 to 2 days after ovulation. sperm It can survive in the female reproductive tract for 2 to 3 days. The fertilization ability is mostly within 24 hours after ovulation. If it exceeds 2 to 3 days, the sperm will lose the ability to combine with the egg. Therefore, it is possible to get pregnant if you have sexual intercourse 2 to 3 days before ovulation and 1 to 2 days after ovulation. This period is called the fertile period or dangerous period. A woman's ovulation date is generally about 14 days before her next menstrual period.

　　For the sake of insurance, we call the 5 days before and 4 days after ovulation, including the ovulation day, a total of 10 days as the ovulation period, and the remaining time outside the menstrual cycle is called the safety period. The safety period is divided into a safety period before ovulation and a safety period after ovulation. The period from the day of menstruation to the day before ovulation begins is the period before ovulation. From the first day after ovulation to the day before the next menstrual cramps is the safety period after ovulation.

　　Can women get pregnant during safe periods?

　　Can women get pregnant during the safe period? It is possible to become pregnant, because contraception during the safe period is not absolutely safe, so there is still the possibility of pregnancy during the safe period.

　　Safe period contraception refers to calculating a period of time during which fertilization will not occur based on a woman’s ovulation period and the time the egg survives in the female reproductive tract, and then having intercourse during this period to achieve the purpose of contraception. The specific reasons why pregnancy is still possible during the safe period are as follows:

　　1. Insufficient understanding of safe period contraception. For people who can successfully achieve contraception through the safe period, it is mainly because they have sufficient understanding and understanding of the safe period. If the understanding in this regard is not very clear, it is a bit pointless to use this method to achieve contraception, because someone has done a survey. Now, the correct understanding of safe period contraception is less than one-fifth of the surveyed people. Most people do not understand it very well and do not know how to calculate the ovulation period and what days the safe period is.

　　2. Because a woman’s ovulation period will be affected by the environment, climate, work, life and emotional conditions, it may be advanced or delayed, and additional ovulation may occur. Therefore, the safe period cannot be 100% accurate. Safe period contraception It becomes less safe.
