For navel protruding inward, long thick line or thin black line, let's talk about it:
1. Look at the shape of the navel.
As the old saying goes, look at the shape of the belly to see the boy and the girl, and look at the navel of the pregnant mother after pregnancy. If the navel is concave, it is usually a boy, and the navel is convex, usually a girl.
2. Look at the navel thickness
Some are thick lines from the navel. Pregnant mothers are usually boys with thin belly button lines, while girls with thick belly button lines.
Mom, tell me about this navel-watching statement:
Why does navel change after pregnancy?
1. After pregnancy, the uterus will squeeze the stomach, the fascia of the stomach will be squeezed, and there will be a prominent feeling;
2. The change of navel is also related to the belly during pregnancy. Some pregnant mothers have strong hips and are not squeezed by tension, so there will be no protruding belly;
3. There is also the pregnant mother is a little tired, the abdominal pressure will increase, the navel will also protrude, and it will become the original appearance after rest;
Everyone studies biology at school. The human chromosome is 23 pairs of 46 chromosomes, and the normal chromosome is 22 pairs. Only one pair of chromosomes is sex chromosome, and the male chromosome is XY. Female staining squeezes the stomach, gastric fascia XX. When men mature, sperm contains 23 pairs of chromosomes.
So it's nonsense to have boys and girls from the navel. Boys and girls are still determined by chromosomes and eggs. The symptoms of appearance can only be said to be a guess, which is a question of probability. Even if you ask the doctor for a B-ultrasound, they say it is likely to be a boy or a girl. No one can tell whether it is a boy or a girl, because no one can tell whether it is a boy or a girl until the child is born. Don't believe it.
