Boys and girls have long known how to know that boys and girls have B-ultrasound. Boys and girls are the same. Don't worry.
Boys and girls have long known what eigenvalues boys and girls have. There is a saying that most boys and girls move from side to side in their stomachs, that is, the left side moves to the right, while the female baby moves around the navel. Girls go left, boys go right! The girl's fetal movement is like a fist, one drum here and one drum there; The boy's fetal movement is like the feeling that a small animal is shaking off its hair or stringing it back and forth, and it will arrive soon. Looking back at the navel, if the girl lies flat or flat or protruding; A boy is a pit. Look at the fetal movement, the more obvious it will be in the future. Most boys kick here and hit there when they move. Although he also turned over, it was rare. Girls also kicked and punched, but it was more like waves in their stomachs, one by one.
The third difference of fetal movement between boys and girls is that it seems that both boys and girls are bulging in their mothers' stomachs, and the boy's baby is bulging with a small bag, as if his little fist or feet were on your stomach. When a girl has a big bag, you will obviously see her belly bulging, as if the baby's * * * is pursed.
Some people say that pregnant boys can't see that they are pregnant from behind, while pregnant girls can obviously see their stomachs from behind. Others say that pregnant boys have sharper stomachs and pregnant girls have rounder stomachs. It is generally believed that pregnant mothers have a hard time, and boys need more energy than girls. This theory has been scientifically confirmed recently. Epidemiologists at Harvard School of Public Health reported in the recently published British Medical Journal that pregnant women with male fetuses eat more food during pregnancy than pregnant women with female fetuses. This is because the energy demand of male babies is greater than that of female babies, so male babies are older than female babies at birth.
Scientists have found that pregnant women who are pregnant with a male fetus consume 8% more protein, 9% more carbohydrates, 1 1% more animal fat and 15% more plant fat than pregnant women who are pregnant with a female fetus. A pregnant woman who is pregnant with a boy eats much more food during pregnancy than when she is not pregnant, but instead of eating different or weird food, she eats the food she usually likes.
Scientists say that the male hormone W ketone secreted by the male fetus W pill sends a "must eat" signal to the mother, greatly increasing her food intake. In addition, although a mother with a male fetus will give birth to a heavier baby, her own weight gain during pregnancy is not heavier than that of a pregnant woman with a female fetus, which shows that the sex of the fetus does not affect the mother's weight.
In addition, some medical staff have done research to predict the sex of babies according to some phenomena. Some recent research reports show that the more serious the pregnancy reaction in early pregnancy, the greater the chance of giving birth to a female baby.
In addition, I will tell you some old people's opinions and doctors' dialectics:
1. Judging from the shape of pregnant women's stomachs, pregnant women's stomachs are sharp and will give birth to boys; When you have a belly, you have a girl. In fact, the shape of the pregnant woman's belly has nothing to do with the sex of the fetus.
2. Observe the changes in the appearance and skin of pregnant women: if the appearance of pregnant women becomes beautiful and the skin becomes smooth, it is possible to have girls; On the other hand, if the appearance becomes ugly, the skin becomes rough, and even the face is covered with acne, it is possible to have a boy. Many people believe this statement, but it turns out that the credibility is not high.
3. Changes in the taste of pregnant women: Some people think that if the taste of pregnant women is different from that of the previous fetus, the sex of the fetus will also change. In fact, pregnant women like to eat sour and sweet, which has nothing to do with the sex of the fetus.
4. The speed of fetal heart: It is generally believed that if the fetal heart is strong and slow, it is more likely that the fetus is a boy; On the other hand, it is a girl. This method of guessing the sex of the fetus has a high probability of error.
5. When I was pregnant with my daughter, my weight only increased by 25kg, which was very standard, with little fetal movement. Basically, it bulges around the navel and rarely feels it. My daughter's biparietal diameter is finally 8.9. When I was pregnant with my son, I gained 45 Jin. My son is moving so badly in his stomach that he seems to jump out. His stomach moved in all directions and finally became very black. My son's biparietal diameter is 10. I don't know if it is accurate. This is my feeling.
In fact, boys and girls are the second, and the most important thing is to wish you a healthy and beautiful baby.
Boys and girls have long known this secret. The Qing dynasty table 20 15 prohibits the birth of boys and girls. 1 It is forbidden to give birth to boys and girls, and it is forbidden to distinguish between men and women in morning urine.

2 1, it is not allowed to be born before the expected date of birth or to meet men and women after the expected date of birth.
22, B-ultrasound shows that the baby's face is facing the male and the female, which is extremely inaccurate.
23, fetal movement to the left male, to the right female. This is extremely inaccurate. 24. A man whose mother's nose gets bigger, and a woman who stays the same. This is extremely inaccurate.
25, the rapid development of * * * after pregnancy is female; On the contrary, it is a man. The accuracy rate is 70%
26, urine for men, on the contrary, women are not allowed. 27, press the thumb, the left hand will quickly return to blood, and the right hand will be female; not allow
28. The left strong pulse is male and the right strong pulse is female. This is not allowed.
29. Fetal movement is earlier in males (before 16W) and later in females. Not allowed.
30. The anterior wall of placenta is male and the posterior wall is female; Not allowed. To sum up, only three items are accurate, and the others are not allowed. In fact, even early B-ultrasound won't show men and women.
If you need to see the baby's mother, you can WX me yzzxnl to help you see the baby's mother and father.
Giving birth to boys and girls has long known the conditions that men and women need to meet when giving birth to boys and girls' gestational sacs;
Number one? B-ultrasound needs to be within eight weeks, because this time is controlled by DNA.
Second? B-ultrasound should have data of three gestational sacs, and two data should be combined with images. When doctors do B-ultrasound, the direction of cross-section is different, some take cross-section and some take vertical cross-section. (Look at my name)
Boys and girls have long known how to know that boys and girls are the same. Boys and girls should not have such old ideas. Now many girls are better than boys. Boys and girls should strive to stand on their own feet and become the pillars of the country.
Boys and girls have long known how to know that the germ cells of boys and girls have 23 pairs of 46 chromosomes, of which 22 pairs are autosomes and I pairs are sex chromosomes. The female sex chromosome is xx, and the genotype is 46, XX. The male sex chromosome is XY, and the genotype is 46, XY. So the ones with Y chromosome are boys and the ones without Y chromosome are girls. Seven weeks ago, I went to Hong Kong Kangning Medical to check my chromosomes, and I got my wish.
Having boys and girls knows how to know that there are many folk remedies for having boys and girls. Look at that.
First, the pregnant woman's stomach is sharp and convex, and she will be pregnant with a boy; Belly type * * *, and then pregnant with a girl;
Second, observe the changes of pregnant women's skin and appearance. If you have acne all over your face, it may be a boy. If your skin is smooth and elastic during pregnancy, it may be a girl.
Third, in terms of taste, according to the law of hot and sour women, the son who loves acid is the daughter who loves spicy;
Fourth, according to the fetal heart rate, if the fetal heart rate is slow, it is a boy, if the fetal heart rate is fast, it is a girl;
Fifth, do a small test and hang a small thing on the upper end of your stomach. If it turns clockwise, it is a girl, if it turns counterclockwise, it is a boy;
6. Look at the data according to the B-ultrasound list. If the length and width are more than double, it is a boy, if the length and width are equal, it is a girl;
Seven, according to the Qing dynasty table, of course, this is just a reference, there is no scientific basis, and the guessed result is not necessarily 100% accurate.
Eight, observe the pregnancy line. If there is a boy on the left and a girl on the right;
Nine, observe fetal movement. If you move before 16 weeks, it will be a boy, and the girl will move later.
Ten, early birth is a boy, late birth is a girl.
This is all seen by the folk earthwork, and there is no scientific basis. Just look at it. The most accurate is to go to Hong Kong Kangning Medical Appraisal in 6 weeks, with an accuracy rate of 99.4%, which is basically impossible to make mistakes.
I knew there was a way to have boys and girls, and it was better to be scientific. Thank you ~ First of all, it is illegal to determine the sex of the fetus!
Then:
What are the methods to scientifically identify the sex of the fetus?
1, DNA blood test: the pregnant woman was diagnosed by B-ultrasound at eight weeks, and the sex of the fetus can be measured under normal circumstances, with an accuracy rate of 98%, which has no effect on pregnant women and fetuses.
2. Amniocentesis: it is mainly used to diagnose whether the fetus has chromosome defects or neural tube defects, and it is usually performed in pregnancy 16~20 weeks. The accuracy rate can reach 99%, but the probability of abortion is 1%.
3. villus sampling: the sex of the fetus can be judged around 12~ 14 weeks of pregnancy, but it may cause abortion (3%~5%), and may also hurt the fetus, resulting in deformity of its hands and feet.
4. Ultrasonic scanning: Ultrasound is a kind of sound wave, which has no adverse effect on the fetus. The accuracy of the baby in March-April must be very high. When ultrasound is used to diagnose the sex of the fetus, the accuracy of male infants can reach more than 95%, while the reliability of female infants is only about 85%.
What are the folk methods to judge the sex of the fetus?
1. Guess whether the Qing dynasty palace table is male or female (the secret recipe table for boys and girls born in the Qing dynasty is calculated according to the lunar calendar, and the pregnant month is delayed by one month if the menstrual cycle exceeds 28 days, and this method is not needed for those with irregular menstruation)

15. After pregnancy, quasi-MM *** becomes stronger for men, and * * * remains unchanged or weakens for women.
16. The fetal movement is male left and female right.
17. The fetal heart rate is about male 140 and female 150.
18. Pregnant prospective MM hardworking male with good mental state and lazy female with poor mental state.
19. Men's noses are bigger, but women have not changed.
20. Before and after quasi-MM urine test, male alkaline urine (above 6.5) and female acidic urine (below 6).
