202 1 year-old boy and girl Qing palace table? The legend of boys and girls born in the Qing Dynasty was invented by a scientist in China. It was based on the deduction of Yin-Yang, Five Elements and Eight Diagrams, and it was calculated by adding time. According to the lunar calendar algorithm, it was clearly listed that 18-45-year-old women were pregnant in different months, so you can know whether you gave birth to boys or girls as long as you sit in the right place. What is the 20021year-old boy and girl table?
First, calculate the expected date of delivery:
According to medical regulations, the expected date of delivery is calculated from the first day of the last menstruation, and the whole pregnancy is 280 days, 10 pregnancy months (each pregnancy month is 28 days). The month of the last menstrual period plus 9 or minus 3 is the expected number of months of delivery; The number of days plus 7 is the expected date of delivery. For example, the last menstrual period is March 4th, 20th 12, the expected date is 3 +9+ 12, the date is 4+7+ 1 1, and the expected date of delivery is1February1/kloc-.
Two, calculate the expected date of delivery before and after the birth of boys and girls:
There is also a saying that boys are prone to "premature delivery", that is, most boys are born before the expected date of delivery, while most girls are born after the expected date of delivery. There is also a method of identification, which can use the four-dimensional color ultrasound diagnostic instrument, which is the most advanced color ultrasound equipment in the world at present. Many pregnant women will habitually ask the doctor if the fetus is male or female after doing the four-dimensional color ultrasound. Although four-dimensional color Doppler ultrasound can clearly see the sex of the fetus, in order to avoid revealing the sex of the fetus during the examination, the doctor will take the initiative to avoid the sex characteristics of the fetus and the lower body. At the same time, when making a CD later, the part that may reveal the sex of the fetus will also be processed.
Third, boys and girls are born through feature calculation:
1, early pregnancy (that is, the first 3 months of pregnancy), no morning sickness, giving birth to a boy; In the first trimester, you will encounter severe morning sickness and give birth to a girl.
2, the baby's heart rate is less than 140 minutes, giving birth to a boy; If the fetal heart rate is at least140th minute, a girl will be born.
3, the color of the areola is relatively deeper, giving birth to a boy; On the contrary, give birth to girls.
4. The bulging belly looks like a full-bodied, tight and round basketball, giving birth to a boy; A bulging belly, like a big watermelon, is not as round as a ball, so a girl is born. In fact, the above statement does not have enough scientific basis. First of all, morning sickness is due to the rapid increase of human chorionic gonadotropin (HCG) level in the early pregnancy, which inhibits the secretion of gastric acid and reduces gastrointestinal peristalsis, thus affecting the appetite and digestive function of expectant mothers. Whether it is a boy or a girl, morning sickness can happen. The personal experience of many pregnant women also shows that the severity of morning sickness has nothing to do with the sex of the fetus.
Fourth, calculate the fetal heart rate to see boys and girls:
Fetal heart rate distinguishes the sex of the fetus, and the accuracy of distinguishing men and women according to fetal heart rate is higher than other characteristics. This has certain scientific basis. Because men's heart rate is slower than women's, it is generally difficult for women to control their emotions when they are angry!
In general, the heart rate is about 140 beats/min when the check-up is more than 5 times, especially those below 140/ min are generally boys, and those above 150 beats/min, especially those above 150 beats/min, account for the majority, and the later pregnancy (after 7 and a half months).
Then, why can't we judge the sex with the fetal heart rate once or twice? Because sometimes the female fetus just goes to sleep when listening to the fetal heart rate, and the fetal heart rate will be lower than that in her normal state, while sometimes the male fetus just moves in her mother's stomach when the doctor measures the fetal heart rate, so the fetal heart rate will be higher than that in his normal state, even exceeding 145 beats/minute. Therefore, it is necessary to have multiple fetal examination reports from the expectant mother to roughly judge the sex.
This calculator method is only for the reference of prospective parents, and I hope it can help you.
How to have sex with a girl? 1, change the acid and alkali. Sperm with X and Y chromosomes swim at different speeds in different pH environments: sperm with Y chromosome is more active in alkaline environment, while sperm with X chromosome is more active in acidic environment. Therefore, if the couple want to have a girl, they can dilute acetic acid with a small amount of clean warm water and then rinse the woman's vagina to make it acidic.
2, sexual intercourse temperature. German researchers tracked the birth records between1946-1995 and compared the local temperature changes. The results show that April to June is the month in which boys are born the most, and October is the month in which boys are born the least. Further analysis shows that the environmental temperature one month before fertilized eggs are combined, that is, the environmental temperature of boys and girls one month before sexual behavior, is an important factor affecting the baby's sex. High temperature environment is easy to create a boy baby, and low temperature environment is easy to create a girl baby.
3. When did you get pregnant? According to legend, it was invented by a scientist in China, and it was charted and buried under a 700-year-old imperial tomb. The authenticity of the origin of the chart is not elegant, but the drawing method is clear at a glance. According to the lunar calendar algorithm, it is clearly listed that 18 to 45-year-old women will give birth to a baby boy or a baby girl at different months. Women only need to "plan" pregnancy on a monthly basis according to the chart, and they can control the birth of boys or girls.
