202 1 year-old boy and girl's table of clearing uterus

Every pregnant parent is very eager to know the baby's sex, but in the legal society, doctors can't reveal the baby's sex according to B-ultrasound, so the people have summarized many methods of giving birth to boys and girls. So what are the tables of boys and girls born in 202 1?

202 1 year-old boys and girls Qing palace table? According to the legend of boys and girls born in Qing Dynasty, it was invented by a scientist in China. Based on the deduction of Yin and Yang five lines of gossip and time, it was transformed into a picture of boys and girls born in Qing Dynasty. According to the lunar calendar algorithm, it is clearly listed that women aged 65,438+08 to 45 are pregnant in different months. As long as they sit in the right position, they can know whether they are born with a boy or a girl. Boys and girls born in 2026, what is 5438+0?

First, calculate the estimated delivery date:

According to medical regulations, the expected date of delivery is calculated from the first day of the last menstruation, the whole pregnancy is 280 days, and there are 10 pregnancy months (each pregnancy month is 28 days). The month of last menstruation plus 9 or minus 3 is the estimated number of delivery months; Days plus 7 is the estimated delivery date. For example, the last menstrual period is March 4th, 20th1February, the expected date of delivery is March 3rd+9th+12, the date is April 7th+1 1, and the expected date of delivery is June 5438+February1.

Two, calculate the expected date of delivery of boys and girls before and after birth:

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 another way to identify, you can use the four-dimensional color Doppler diagnostic instrument, which is the most advanced color Doppler equipment in the world. Many pregnant women will habitually ask the doctor if the fetus is male or female after doing four-dimensional color Doppler ultrasound. Although four-dimensional color Doppler ultrasound can clearly see the sex of the fetus, in order to avoid exposing the sex of the fetus during the examination, doctors will take the initiative to avoid the sex characteristics and lower body of the fetus. At the same time, when the CD is produced 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 three months of pregnancy), no morning sickness, giving birth to a boy; In the first trimester, you will encounter severe morning sickness and have 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 least 140 minutes, a girl will be born.

3, the areola color is relatively deeper, giving birth to a boy; On the contrary, give birth to girls.

4. The bulging belly looks like a full, 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 was 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 early pregnancy, which inhibits gastric acid secretion 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!

Generally, the heart rate is about 140 beats/min at more than 5 prenatal examinations, especially those below 140 beats/min are generally boys, and about 150 beats/min, especially those above 150 beats/min are the majority, in the third trimester (after 7 and a half months)

So, why can't we use the fetal heart once or twice to judge the sex? Because sometimes a female fetus just falls asleep after listening to the fetal heart rate, the fetal heart rate will be lower than that in her normal state, and sometimes a 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 of expectant mothers to roughly judge gender.

This calculator method is only for parents' reference, and I hope it can help you.

How to have sex with girls? 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 couples want 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 between 1946- 1995 and compared the local temperature changes. The results show that April to June is the month with the most boys born, and 10 is the month with the least boys born. 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 intercourse, is an important factor affecting the sex of babies. High temperature environment is easy to bring up boys and babies, and low temperature environment is easy to bring up girls and babies.

3. When did you get pregnant? According to legend, it was invented by a scientist in China. It was charted and buried under an imperial tomb 700 years ago. The authenticity of the source 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 get pregnant in different months and give birth to a baby boy or girl. Women only need to "plan" pregnancy on a monthly basis according to the chart, so they can control whether to have a boy or a girl.
