What are the signs of pregnancy? Epidemiologists at Karolinska Medical College in Stockholm, Sweden have confirmed that women who have severe early pregnancy reactions in the first three months of pregnancy are more likely to have girls than boys. Scientists investigated more than 1987 to 1995 newborns in Sweden. The ratio of male to female is generally 50%, which is normal. However, when only 5,900 pregnant women who were admitted to hospital for treatment due to severe dizziness, vomiting and other early pregnancy reactions (pale face) in the first three months of pregnancy were studied, it was found that the proportion of boys and girls born to them was 44%.
China's traditional thought is to have a boy, so many people want to predict the sex of the fetus and see if the baby is a boy or a girl. So, what are the signs of pregnancy? Let me introduce you to the characteristics of having a boy.
1.B type belly is a boy.
2. Is the navel protruding a boy? On the other hand, girls.
Pregnancy line is a thin, long and straight boy.
4. Early B-ultrasound fetal sac length. For example, on the 52nd day of pregnancy, the gestational sac is 4.2*2. 1* 1.4.
5. It is said that the biparietal diameter-femur length is greater than 2.
6. It is more likely to have a boy before the placenta.
7. Urine test during pregnancy shows that HP value is rising, and it is a boy.
8. In the third trimester of pregnancy, due to the increase of male hormones in pregnant boys, the thighs, armpits, areola and neck of expectant mothers are all black.
9. It's a boy with a big nose.
There are many ways to measure boys and girls with a pencil and predict boys and girls, some are secret in the palace, and some are circulated among the people. Recently, I found a strange method: pencil prediction. How to test boys and girls with pencils? The specific methods of measuring boys and girls with pencils are as follows:
1. First, prepare an ordinary rubber-tipped pencil and a sewing needle with thread (that is, the kind of needle we usually nail buttons);
2. Insert the needle into the center of the pencil eraser. Note: it must be in the center, not left or right, and the needle should be vertical and not skewed;
3. Ask your partner to help you pick up the thread on the needle and hang the whole pencil vertically above the right hand artery, not too far away from the artery, keeping a distance of about 3-5 mm;
Finally, carefully observe the movement of the pencil tip: at first, the pencil will shake like a circle. At this time, you should wait calmly for the pencil to stop automatically. After shaking it several times, the pencil will stop automatically and then move up and down or left and right regularly. If the pencil moves up and down, it means you will have a son; If it moves left and right, it means you will have a daughter. If it is left first, then right and then up and down, it means that the first child will have a daughter, the second child will have a son, and so on!
Reminder: It is said that this method is only effective if you are pregnant for more than 3 months, because BB has already formed and generated a magnetic field.
