Don’t know the danger period? Is the ninth day after menstruation a dangerous period?

　　As we all know, the safety period is generally female The seven days before menstruation and the eight days after menstruation are the first seven days and the last eight days. However, this does not mean that you will not be pregnant. So, is the ninth day after menstruation a dangerous period? When is the dangerous period? , when is the safe period for women?

　　Is the ninth day after menstruation a dangerous period?

　　No. Except for the menstrual period and ovulation period, the rest of the time are safe periods for women. 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. This method is not advisable for women with irregular menstrual cycles.

　　The safe period for women is mainly calculated based on the ovulation period and menstrual cycle. In addition to the calendar method, the safe period can also be calculated through the basal body temperature measurement method and the secretion observation method. Combining the above three methods to calculate the safety period can improve the accuracy. It is worth noting that the safe period is not absolutely safe. Sometimes women will ovulate early or delayed, and the judgment of the safe period will become invalid.

　　When is the safe period? Except for the menstrual period and ovulation period, the rest of the time are safe periods. Women's 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.

　　A woman's ovulation period is generally about 14 days before her next menstrual period. For the sake of safety, we call the 5 days before and 4 days after ovulation, including the ovulation day, a total of 10 days as the ovulation period. Generally speaking, the ovaries of women of normal reproductive age only release one egg per month. Eggs can survive for 1-2 days after ovulation. sperm It can survive in the female reproductive tract for 2-3 days, and the fertilization ability is mostly within 24 hours after ovulation. If it exceeds 2-3 days, the sperm will lose the ability to combine with the egg. Therefore, it is possible to get pregnant if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation. This period is called the fertile period or dangerous period.

　　What is the safe period and dangerous period

　　In fact, the safe period and the dangerous period are relative terms. So how are the dangerous period and the safe period defined? In fact, generally speaking, the dangerous period is the time interval when the egg meets the sperm and can become a fertilized egg and become pregnant. The time opposite to the dangerous period can be called the safe period. Judging from the time that the egg can be fertilized after ovulation and the sperm's survival time, based on the ovulation day (usually 14 days before menstruation), the first 4 days and the last five days are the dangerous period, and the rest is the safe period.

　　In fact, the safety period and dangerous period Both terms are for contraception. If you want to get pregnant, it is best to have sex during the dangerous period. The safe period is generally considered to be "the first seven days and the last eight days." It is considered that the 7 days before and 8 days after the menstrual period are safe, but this is just a general rule. In fact, generally speaking, the safety period before ovulation is 7 days, and the safety period after ovulation is 8 days. But in fact, the safe period is divided into a safe period before ovulation and a safe period after ovulation. The dangerous period refers to the fertile period (ovulation period), which is a few days before and after ovulation. It generally refers to the 5 days before and 4 days after ovulation. If counted together with the ovulation day, it is a total of ten days.

　　It is difficult for ordinary people to distinguish between safe periods and dangerous periods. In fact, safe periods and dangerous periods are relative terms. Both are named from the perspective of "contraception", and are mainly defined based on the ovulation day or ovulation period. If we want to distinguish the safe period and the dangerous period, it is best to have a certain understanding of the ovulation period, because the safe period and the dangerous period are mainly distinguished based on the ovulation period. If you want to know the ovulation period, it is best to use detection methods such as ovulation test strips.

　　In fact, as long as the ovulation day is determined, the safe period and the dangerous period can be easily distinguished. Generally, we call the 5 days before and 4 days after the ovulation day, together with the ten days of the ovulation day, the dangerous period, and the remaining time is generally called the safe period. So if you want to know when the safe period and the dangerous period are, you need to have a certain understanding of the ovulation period. In fact, the safe period and dangerous period are mainly based on the concept of "contraception", so the distinction between safe period and dangerous period is also based on the body's reaction during the fertile period (ovulation period).

　　How to prevent pregnancy during safe and dangerous periods

　　Chances of getting pregnant during dangerous periods Although the chance of pregnancy during safe periods is very low, in order to ensure that there are no worries, if you can't hide your "sexual" interest and don't want to have a love child so quickly, how can you effectively prevent pregnancy during safe periods and dangerous periods?

　　I have said before that the most important thing about safe period contraception is to know the ovulation day. If we want to successfully prevent pregnancy during the safe period, we must first start with the method of detecting ovulation. Only by understanding the ovulation period can we effectively avoid it and achieve the contraceptive effect. If you don’t want to use ovulation test strips to check, self-examination by measuring body temperature and paying attention to leucorrhea is also a great way. Measuring body temperature is the basal body temperature when you wake up in the morning before doing any activities.

　　Starting from the first day of menstrual cramps, put the thermometer in your mouth for 5 minutes, and then draw the measured temperature in the square with small dots until one day before the next menstrual cramps, and connect the dots to form a curve. Ovulation generally occurs before the body temperature rises or during the process of rising from bottom to high. Usually the ovulation period is within 3 days when the basal body temperature is high. Pay attention to leucorrhea, which is a few days before ovulation in the middle of menstruation. Compared with before, the leucorrhea will become clearer like egg white, smooth and elastic, and can be stretched into very long threads. The day with the longest threadiness is likely to be the day of ovulation. This day and the 4-5 days before and after it are the dangerous period.

　　If you want to prevent pregnancy during the dangerous period, you usually need the assistance of external tools. Because the chance of pregnancy during the dangerous period is greatly increased, so if you want to ensure that you can enjoy sex without getting pregnant, the best method of contraception is to wear condoms or take birth control pills.
