I always hear that pregnant women need to go through ten months of pregnancy, so how many weeks does

Fetuses are generally born around 40 weeks of pregnancy, and some fetuses are two weeks earlier or two weeks later, which is normal.

The baby is generally about 37 to 40 weeks can be born, if more than this time or before, this first automatic may be premature, or the impact of the baby is still very serious, how the baby was not born in this time period, the mother should be vigilant.

Born at 40 weeks, this should be determined according to the physical condition, under normal circumstances, it is 40 weeks, and there are also early and postponed.

Pregnancy in October is forty weeks, from the first day of the last visit to the aunt, the baby in the mother's belly from very small, as the month will get bigger and bigger, slowly grow out of various organs and limbs, in the mother's belly to develop perfectly, will be born by the mother.

Pregnancy in October is 37 to 39 weeks. It is calculated from the last day of menstruation, and the date of pregnancy and the expected date of delivery of the child are estimated. The fertilized egg begins to grow gradually in the uterus.

4 months of pregnancy is between 38 and 40 weeks of pregnancy. It is counted from the day the fertilized egg is formed. The baby will continue to develop in the mother's belly.

<> when the fetus is 24 weeks old, it can distinguish between different sounds inside and outside the mother's body. At 32-35 weeks, hearing quickly becomes acute and turns the head to a sound source, so the mother can often talk to her child or listen to the same**. After pregnancy, female friends will not only pay attention to the healthy development of the child's abdomen, but sometimes they will be curious about what the child does in the mother's stomach every day?

She wanted to live in the amniotic fluid in her mother's womb. His stomach is dark and the child has little room to move. Doesn't the child sleep and eat every day during this time?

In fact, before he was called a fetus, he began to swim in his mother's womb. This aimless swimming has no posture, just like a seahorse. This activity continues from the sixth week of pregnancy until it is too large to float in the amniotic fluid.

It can move its arms freely, bend its fingers and toes, bend, and the human body is made up of two types of cells with different structures and functions. One is the germ cell, which contains all the genetic material of the fetus. The other is somatic cells, which make up various organs of the body, such as bones, muscles, digestive system, muscles and muscles, respiratory, circulatory, nervous system, etc.

Stretch his little arms and legs, suck his fingers, chew his feet, play with the umbilical cord, etc.

The third germ layer blastocyst formation develops to the fourth week. The growth rate of each part of the blastocyst is different, left and right, front and back, the head and tail are bent at both ends, swelling to the center, forming a "C" shape, extending into the amniotic cavity, and the shape is incubated into a cylindrical embryo, which is seen to bud the upper limbs at 26 days and the lower limbs at 28 days. At 10 months of pregnancy, about 280 days, the fetus sleeps in the mother's stomach most of the time.

Because children's sleep is more conducive to children's hair and lack of growth. But the child is also awake. Now, he might be a bad boy.

At this time, the child can swim in the amniotic fluid, stretch his little arms and legs, suck his fingers, chew his feet, play with the umbilical cord, etc.

They also have some movements, they will kick, and they will also suck things to absorb some nutrients from the pregnant woman's body.

The fetus has its own thoughts in the mother's womb, has its own thoughts, and may kick around, which is just playing.

The fetal pei ant has been growing and developing, and the fetus is also absorbing some camp car socks, and the longer the sail is buried, the longer the fetus grows, and it will be born at a certain time.

It's been growing up in a clump, and the volume will become bigger and bigger, and if the month gets bigger and bigger, there will be limbs, and it will also be accompanied by a heartbeat, and slowly there will be feelings.

As we all know, babies are generally born after the mother's body is fully developed and developed, and this process generally goes through about ten months. That is, people often say "October pregnancy, once delivery", now the medical technology is more developed, parents can clearly see the development of the child in the belly, however, there are many people are also very curious about this, in the process of pregnancy in October, what does the fetus do in the mother's belly? To this question, the relevant obstetric experts gave a clear answer, and the fetus generally does the following things in the mother's womb:

Since no one talks to the fetus in the mother's womb, in fact, the baby is also very boring in the mother's womb, and the umbilical cord is the only thing that the fetus can touch. There is a scientific basis for this, and sometimes, from the B-ultrasound, the fetus willThe umbilical cord is wrapped around the neckIn fact, this phenomenon is because the fetus is naughty and active, so that the umbilical cord is wrapped around the neck.

Generally speaking, if a pregnant woman feels that her baby is constantly moving when she is five or six months pregnant, it means that the fetus may be thereSwallow amniotic fluid。From a scientific point of view, the fetus is learning to swallow and prepare for food after birth. In fact, many mothers often feel that their children are moving, and it is not excluded that some children are naturally more naughty and active, in fact, more often than not, the baby should be swallowing amniotic fluid.

As we all know, if you put newborn children in the water, they are born to swim, but after living on land for a long time, they gradually forget how to swim. In fact, the fetus is in the mother's body, and it begins to learn to swim. Because the fetus can only exist at all timesAmniotic fluidIf the fetus wants to move, or feels uncomfortable moving, then it must learn to swim, so that it can move more flexibly in the mother's belly.

Generally speaking, this is only done when the fetus is relatively small.

All in all, not only growth and development, but also a lot of things that the fetus can do in the mother's body.

In the process of pregnancy for ten months, what the fetus should do is to absorb the nutrients given by the mother, and then work hard to grow up, and to grow up perfectly.

As the child grows up, the child will become larger and larger, the relationship with the parents will become better and better, the nutrient intake will become more and more comprehensive, and the embryonic development will become more and more complete.

The fetus will also have some movements, some reactions in the belly, and will also absorb some nutrients.
