Many people can't wait to know whether the baby in their belly is a boy or a girl when they are pregnant, but the doctor doesn't say when they die. Relatives and friends suggest that through the shape of their belly and navel, we can see nine out of ten. Is that true?
Can't help but want to know the belly of men or women treasure, so I collected more than 80 big belly mother guess men and women's posts to see. The result is amazing. As long as it's nubao's stomach, the lower end of the belly is inverted trapezoid, and the lines are more prominent and angular. The more obvious the trapezoid, the higher the accuracy. Here is an example:
Typical belly shape of nubao:
But the lower part of the belly of the man treasure is more smooth and full, without that kind of outstanding line.
Men's belly type:
No matter how the above mothers react during pregnancy, whether the fetal movement is early or late or whether the navel is prominent, as long as the belly meets the characteristics of the above women's treasure, 99% of them may be women's treasure; 90% of them may be men's treasure. Other mothers who want to know the sex of their babies in their stomachs can compare the above-mentioned belly shapes. Just look at the shape of the belly below, and the answer is clear at a glance.
Saying 1: if the fetal heart rate is lower than 140 times / min, the baby is a boy
The heart rate of a girl is higher than that of a boy, which is just right at birth. The heart rate of a fetus is no difference between a boy and a girl. The speed of heart rate only changes with the age of fetus. At about 5 weeks of gestation, the fetal heart rate is close to that of the mother, i.e. 80-85 beats / min. Then the heart rate gradually increased to 170-200 times / min in the period of 9 weeks gestation. After that, it gradually slowed down to 120-160 times / min in the period from the second to the second trimester.
Saying 2: pregnant women with too much abdominal protrusion are girls, while those with less or lower abdominal protrusion are boys
If the upper body of a pregnant woman is short, the space for fetal development can only be extended outwards, so the abdomen will be very large.
On the contrary, the upper body length of the pregnant woman can provide enough space for the development of the fetus, and the abdomen does not need to protrude outward.
Myth 3: a pregnant woman has a boy in her lower arms and a girl in her upper arms
If the pregnant woman is pregnant, it may be her first pregnancy or her body shape is good. When pregnant women have a pregnancy, abdominal muscle relaxation, again pregnant when the natural 'droop'.
Myth 4: Black nipples are boys
The color of the nipple is affected by the hormone in the body. The increase of progesterone and the hormone level that stimulates the melanocytes in pregnancy results in the blacker parts on the body surface, which will recover soon after the birth of the baby. This phenomenon has nothing to do with the sex of the fetus.
Saying 5: the relationship between eating acid and alkali and giving birth to boys and girls
It's a mistake to know whether a food is acidic or alkaline only by its taste. It should be emphasized that the state of acid-base imbalance in human body is usually caused by illness.
Saying 6: the reaction of early pregnancy is to eat sour and spicy food
There is no scientific basis for the saying "sour and spicy". Medically speaking, the birth of boys and girls is mainly determined by chromosomes. In the mother's body, all of them have X chromosomes, while in the mother's body, there are x or Y chromosomes. If they enter the X chromosome, they are girls; if they enter the Y chromosome, they are boys. So it's really up to the father to decide whether to have a boy or a girl. In a certain sense, there is a relationship between male and female fertility and the environment around the fallopian tube.
Saying 7: do you have a girl in the morning?
Experts said: according to 5900 pregnant women who were admitted to the hospital because of their serious unhappiness at the early stage of pregnancy, the results showed that 56% of them gave birth to female babies and 44% of them gave birth to male babies. However, in the middle and late pregnancy, the sex ratio of the baby is similar to that of the normal distribution.
Saying 8: the doctor prescribes a secret recipe to give birth to boys and girls
The doctor has made five Secret Recipes:
First, ask the pregnant woman to sleep on her left side, because when she is 3 months pregnant, the baby still falls on the uterine wall. This method is very necessary. You know, sleeping on the left side gives birth to a boy and sleeping on the right side gives birth to a girl. '
'second, put an axe under the bed of the pregnant woman. Remember, the axe is facing up. Don't touch it after putting it. We have done experiments on this. In fact, we put a piece of iron in a chicken coop, and all the chickens hatched are cocks. '
"Third, find a rooster, pull out the three longest hairs on his tail, wrap them with his nails and hair, and put them under the pregnant woman's bedspread. '
'fourth, we can't eat meat. We can only eat simple food. It has been the same since ancient times that eating vegetarians gives birth to sons and eating meat to give birth to daughters. Think about that. '
"Fifth, the orientation of the head of the bed is also important.
"It's decided by chromosomes to give birth to boys and girls. As soon as a pregnant woman is pregnant, the sex of the fetus is determined. Which can be changed at will? It's totally against the science!"
