diagram of fetal position changes in November-September pregnancy

Diagram of fetal position changes in November-September pregnancy shows that pregnancy is a happy and hard thing. From January to October, it seems to be a long and short process. Generally speaking, we can only see the baby from the second month. Let's take a look at the fetal position changes in pregnancy from January to September. Fetal position changes from November to September of pregnancy Figure 1

One month (-4 weeks) of pregnancy < P > Development focus: fertilized eggs form embryos and complete implantation.

pregnant for 2 months (5-8 weeks)

development focus: the body length is about 1.7-3.5cm, and the weight is about 4g, and human figures begin to appear, and the limbs will also show in the form of granulation.

pregnant for 3 months (9-12 weeks)

Development focus: the body length is about 6.5-9cm, and the weight is about 5-32 grams. The fetal head accounts for about the whole body length, the forehead protrudes forward, the head becomes longer, and the lower jaw has been formed.

pregnant for 4 months (13-16 weeks)

Development focus: the body length is about 15-17cm, the weight is about 11-13 grams, and taste buds begin to appear on the tongue, resulting in a sense of taste. The proportion of head and body is almost the same, and the five senses become more obvious. , the whole body skin is transparent pink, nails have been fully formed.

pregnant for 5 months (17-2 weeks)

Development focus: the body length is about 2-25cm, the weight is about 3-5 grams, the sexual organs are mature, and the male baby's vulva-stem and scrotum are gradually enlarged. Fat begins to produce, and white fetal fat begins to produce on the surface of skin, which is beneficial to protect skin and smooth delivery.

pregnant for 6 months (21-24 weeks)

Development focus: the body length is about 28-3cm, and the weight is about 6-75g. The eyelids of the fetus have formed, and they can open their eyes by themselves. Because the fat has not been fully formed, the fetal skin is thin and pink and looks wrinkled. A baby girl's ovaries will make eggs.

Seven months pregnant (25-28 weeks)

Developmental focus: the body length is about 35-4cm, and the weight is about 1-12 grams. The brain is quite mature, and it can change the direction of the body according to its will, and it can stretch, contract and grasp.

The development of fetal thinking, memory and various emotions began to sprout.

pregnant for 8 months (29-32 weeks)

Development focus: the body length is about 4-42cm, the weight is about 13-18 grams, and the hearing, vision, touch, taste and smell have all been developed. The increase in body length and weight makes the activities more restricted, but the posture can still be changed at will, so that the mother can obviously feel the fetal movement.

pregnant for 9 months (33-36 weeks)

Development focus: the body length is about 45-5cm, and the weight is about 19-26 grams. The head of the fetus becomes very large. At this time, the brain tissue has developed rapidly to a certain extent, and the brain volume has increased sharply, and the wrinkles and grooves unique to the brain can be clearly seen.

Most important organs, such as circulation, respiration, digestion and sex organs, have been developed, and the fetus begins to gain weight to prepare for birth. Figure 2

Pregnancy 1 month (1-4 weeks): Fetal length: about .2cm, weight: about 1g

The fetus in the first month is still a fertilized egg, which is called a embryo. The fertilized egg splits to form a morula and continues to divide to form a blastocyst and is implanted. The fetal central nervous system and heart began to develop.

2 months (5-8 weeks) of pregnancy: fetal length: about 1.7-3cm, weight: about 4g

At the end of 2 months of pregnancy, the fetus has been able to distinguish the outline of the head and trunk, and the tail is smaller. The eyes, ears and lips appear roughly and have the outline of the face, but the eyes are still on both sides, and the bones are still cartilage.

Now the organs of the fetus have begun to have obvious characteristics, and there seems to be a small amount of webbed objects between fingers and toes, which start to move like jumping beans.

pregnant for 3 months (9-12 weeks): fetal length: about 6.6-9cm, weight: 5-6g

after three months of pregnancy, the baby has begun to take shape. At this time, the growth speed is even more alarming, with the body and legs all grown up, but the head is still obviously larger. More importantly, the nose, gums and vocal cords have grown out.

The fingers and toes of the fetus are completely separated, and the eyes, fingers and toes can be clearly distinguished. Some bones began to become hard, hair and nails began to grow, and external genitalia began to develop.

pregnant for 4 months (13-16 weeks): fetal length: 15-18cm, weight: 11-13g

The baby who has been pregnant for 4 months has begun to develop neural channels in the brain. At this time, the baby has been able to clearly perceive the external environment and become sensitive. When he is nervous, he will pinch his little hand into a small fist and his toes often.

pregnant for 5 months (17-2 weeks): length: about 25cm, weight: about 34g

When pregnant for 5 months, the various organs of the fetus gradually grow and start to operate, and their hearing is more acute, so they can hear not only the heartbeat of their mother, but also the outside world. At this time, their father and mother can talk, sing and interact with their baby more, and the baby will be very happy.

Five months have passed in a blink of an eye. With the integration of nervous system, the baby can kick and suck his fingers very fluently. Some babies also play with umbilical cord and circle in their mother's belly.

pregnant for 6 months (2-24 weeks): fetal length: about 3cm, weight: about 6-7g

At this time, the hair, eyebrows and eyelashes of the 6-month-old fetus can be clearly seen. And the baby's eyelids have formed, so you can open your little eyes and see the world in your mother's belly. The body looks symmetrical, but there is less subcutaneous fat and the body is still thin. His skin is yellow and he looks like a little old man.

Seven months pregnant (25-28 weeks): length: about 35-4cm, weight: about 1-12g

The fetus at seven months old has increased skin thickness, exuberant fat secretion, and the whole body is covered with fetal fat, so the skin becomes ruddy and no longer transparent, but the whole body is still covered with a thin layer of fluff.

Although the facial features look the same as those of a newborn, the baby is wrinkled like a little old man because the fat has not been fully formed, but the brain has developed quite maturely, and it has begun to perceive emotions, think and have its own fixed sleep cycle.

8 months pregnant (29-32 weeks): length: about 4-42cm, weight: about 13-16 g

The baby grows rapidly during these 8 months, almost filling the whole uterus. Because the activity space becomes smaller, the baby will reduce the activity at this time, but the pregnant mother can obviously feel the baby's fetal movement; The baby's subcutaneous fat is also gradually generated, ready to adapt to the temperature changes outside the uterus.

pregnant for 9 months (33-36 weeks): length: about 45cm; weight: about 2-25g

pregnant for 9 months is getting closer and closer to delivery. At this time, the fetal changes are the most obvious, wrinkles are reduced, the body is rounded, and the internal organs are fully developed. Now the fetus is a round and chubby baby.

Some fetuses have started to descend into the pelvis at this time. Whether the fetal position is normal at this time is directly related to whether the pregnant woman can give birth smoothly. If the fetal hip is down or the fetal position in other postures is not correct, the doctor will take measures to correct it according to the situation.

pregnant for 1 months (37-4 weeks): length: about 5-52cm, weight: about 27-33g

The baby's organs are mature, and the pregnant mother can give birth at any time. The baby is making final preparations to see his mother, and the fluff on his body disappears and his skin becomes slippery; Amniotic fluid becomes turbid from the original clear and transparent due to the shedding of villi and fetal fat on the body surface and the production of other secretions.

conclusion: the pictures of the belly after 1-1 months' pregnancy show us the hardships of the expectant mother's pregnancy in October, and also show us the development changes of the fetus at various stages from 1-4 weeks. As long as you can give birth to a healthy baby, I believe all the hard work of the expectant mother is worth it. Figure 3

Changes of fetal position during the first nine months of pregnancy. When does the baby twist her head?

Generally, the baby will become the head position at 3 weeks. Generally, if everything is normal, the baby's fetal head position will gradually decrease to the first position after June and July, but if the fetus is horizontal, it's hard to say what week it just started. There is also an early change from hip position to head position. If mother Bao doesn't have a fetal umbilical cord around her neck, she can do a fetal orientation correction exercise under the specific guidance of a doctor.

It's much less likely to be transferred from breech position after 3 weeks. However, there are exceptions, for example, if the baby is small, the mother's pelvis is relatively large, and she will be transferred in the late pregnancy. Generally, after 3 weeks of pregnancy, most of them can naturally turn to the first presentation. Therefore, the baby will generally become the first place in 3 weeks.

What is the whole process of fetal orientation change?

In the whole process of creation, the head grows faster, so the head position of the baby is constantly changing. 8 weeks-11 weeks: (The test-tube embryo will grow and develop soon-the growth and development will proceed) The head position is relatively positive. 12 weeks (March)-16 weeks: < P > (The baby's body, the rest weight increases rapidly) The fetal head position has just begun to lean forward. May (17 weeks-2 weeks): The baby's head position is more forward. July: The baby's head position is directly below the basic house. September-38 weeks: (The baby has basically completed the growth and development) The baby's head position is completely facing the house directly below (it has already been prepared for birth in advance).

In the whole process of the growth and development of the baby in the belly, expectant mothers hope to spend these ten months and pay close attention to the situation of the baby in the belly, so they don't want to miss a key point. The growth and development of the fetal baby's head is particularly important, which is related to the quality of food, clothing, housing and transportation after the newborn is born and grows up. Therefore, the change of fetal head position is the most important concern.
