Five months pregnant, what new changes will the baby and pregnant mother have?

After five months of pregnancy, mothers have already traveled halfway. Do mothers suddenly feel that time flies? At this point, the mothers' early pregnancy reaction has almost disappeared, bid farewell to the early discomfort and passed the high incidence of abortion. What new changes will happen to the baby and pregnant mother at this time?

I am pregnant for 5 months, that is, 17-20 weeks. At this time, the baby changes:

Pregnancy 17 weeks: pregnancy 17 weeks, the baby's head and buttocks are about 12.7cm, and the baby's weight is about150g. The baby has not started to form fat, so it still looks thin. The baby has grown fine hairs all over his body, his eyebrows are standing up, all his organs are well developed and his stomach has appeared.

Pregnant 18 weeks: pregnant 18 weeks, the baby has completely propped up the mother's lower abdomen. At this time, the baby's head and buttocks are about 14cm long and weigh about 200g g g. At the final stage of completion, the respiratory center begins to move, the duodenum and large intestine begin to fix, and the digestive organs begin to work. At this time, the baby's strength increased a lot.

Pregnancy 19 weeks: At pregnancy 19 weeks, the baby's head and buttocks are about 15cm long and weigh about 250 g. The baby's body is covered with a layer of fetal fat, which will protect the baby and prevent the baby's sensitive skin from directly contacting the surrounding amniotic fluid. In this week, the biggest change of the baby is that the sensory organs of ta begin to develop rapidly by region.

20 weeks of pregnancy: At 20 weeks of pregnancy, the baby's head and buttocks are about 16cm long and weigh about 320g g g. During this period, the baby's limbs have developed well and the baby has begun to be active. Most mothers can already feel the baby's fetal movement at this time, and ultrasound examination can already distinguish the baby's gender.

After talking about the changes in the baby after 5 months of pregnancy, let's talk about the changes in the mother after 5 months of pregnancy:

When I was pregnant for 5 months, my mother's uterine bottom reached the navel, and mothers could no longer hide the fact of pregnancy. This is because most mothers are pregnant. The abdomen is getting bigger and bigger, and the weight increases sharply, almost increasing by about 3.5 kg, which is close to the typical pregnant woman's body shape. I can't tell where my waist is and where my stomach is. At this time, not only the mother's body shape has changed, but also her breasts have changed greatly.

In addition to some physical changes, a mother who is pregnant for 5 months will have the following feelings:

To put it simply, the baby's body length is about 25cm, the head and buttocks are 16cm, and the weight is about 320 g. At this time, the baby's body surface is covered with a layer of fat similar to cheese, which is what we call fetal fat. The baby's alveoli are also developed, but gas exchange is impossible. The baby will suck his thumb and swallow the amniotic fluid in his mother's stomach, and has already had the function of urination.

After five months of pregnancy, mothers are basically pregnant. At this time, the early pregnancy reaction disappears and the stomach will not be too big. Mothers are still very comfortable. Of course, there will be some minor problems, such as frequent hunger, occasional abdominal pain, false contractions, frequent urination and so on.

Fetal development in the fifth month of pregnancy;

What changes have been made to pregnant mothers?

① The uterus rises to the height of navel and is full of pregnancy.

My feet seem to be getting bigger.

Because more liquid absorbed by the whole body will remain on the ankles and feet, weight gain will also bring pressure to the feet. Under normal circumstances, pregnant mothers need to wear shoes that are half or one size larger than usual.

At this time, mothers can relieve themselves by lifting their legs, reducing standing, doing foot exercises or massaging.

(3) The eyesight may decrease, the eyes are dry and sensitive to sunlight.

Mother's brain starts to work, and she often feels out of state or forgetful.

Hello, I am the obstetrician of Hangzhou Maria Maternity Hospital, and I am glad to answer your question.

Physical changes of expectant mothers who are pregnant for five months

After five months of pregnancy, the expectant mother's weight will increase significantly, and a large amount of fat will begin to accumulate all over the body, such as buttocks, inner thighs and arms, and the chest circumference and hip circumference will become larger. The heart is overburdened. Because the uterine compression is getting bigger and bigger, pushing the gastrointestinal tract upward, it becomes difficult to breathe. Sometimes the stomach is full, difficult to digest, and chest tightness.

During this period, the demand for blood by organs such as the uterus of expectant mothers nearly tripled, so the burden on the heart began to increase gradually. May cause hemorrhoids. As the baby grows up, it begins to oppress the expectant mother's rectum. After the rectum is squeezed, the vein will swell out, and in severe cases it will protrude out of the anus.

If the expectant mother has constipation, it will be even worse. Drink plenty of water and exercise properly at this time. The increase in secretions is a normal phenomenon, because the demand for blood from various organs in the whole body increases in the second trimester of pregnancy, especially the blood flow around the vagina.

Fetal development at five months of pregnancy

At this time, the fetal head has occupied 1/3 of the whole body length, and the entrance of the ear is open; Gums begin to form; Hair and eyebrows are all finished. Fingers and toes grow under the nails, which are convex. The baby will lick his thumb with his mouth, just like tasting the taste of fingers.

The fetus is about 16.5cm long from head to toe, 25.4 cm long from head to toe and weighs 250g. The average diameter of biparietal is 4.88 0.58 cm, the average abdominal circumference is 65,438 0.49 cm, and the length of femur is 3.35 0.47 cm.

Fetal changes

The overall change of the baby this month

By this month, the baby's head has accounted for1/3 of the whole body length; There is a thin layer of fetal hair on the head and body, and white fat gradually covers the skin; Fingers and toes grow nails, and they are convex; The entrance to the ear is open; Gums begin to form; Hair and eyebrows are complete; With the deposition of subcutaneous fat, the skin becomes translucent, but the subcutaneous blood vessels are clearly visible; Bones and muscles are getting stronger and stronger; Reproductive organs are also close to taking shape; I can hear my mother's heartbeat, arterial blood flow and bowel sounds. If I use a stethoscope, I can hear his heart sounds.

17 weeks

17-week-old baby, about 13cm in length and 150g in weight, looks like a pear. During this week, expectant mothers can hear the baby's strong heartbeat with the help of a stethoscope. At this time, the baby's bones are still cartilage, and lecithin that can protect the bones begins to slowly cover the bone marrow.

18 weeks

By week 18, the baby grew to about 14 cm and weighed 200g. This week, the alveoli in the lungs began to develop, and the small chest has been bulging, indicating that it is breathing. But at this time, it is amniotic fluid that is inhaled and exhaled, not air.

At this time, if you pass the B-ultrasound examination, you can clearly distinguish whether it is a male baby or a female baby. If it is a female baby, then her vagina, uterus and fallopian tubes are all in place. If it's a baby boy, the genitals are clearly visible. Of course, sometimes because the baby's position is different, the small genitals will be covered.

19 weeks

/kloc-the baby at 0/9 weeks is about 15cm in length and weighs 200 ~ 250g g. Skin glands began to secrete glandular fat, nipples appeared and began to swallow amniotic fluid. After the kidney was filtered, they turned it into clean urine and discharged it into amniotic fluid again. The filtered dregs accumulate in the intestine to form meconium, which is excreted after birth, and the hair is growing rapidly.

His movements become active, he can poke, kick, twist, turn, lick his intestines and suck his thumb with his mouth, just like tasting the taste of his fingers. In this week, the biggest change of the baby is that the sensory organs begin to develop rapidly by region. From now on, taste, smell, touch, vision and hearing develop in special areas of the brain. At this time, the number of neurons decreased and the communication between neurons began to increase.

20 weeks

The 20th week is a critical period for the development of baby's sense organs such as taste, smell, vision and touch. At this time, its state has stabilized, with a body length of 16cm and a weight of 255 grams. At this time, the baby is growing rapidly, the hair continues to grow, the fetal fat increases, the skin thickens and develops into four layers.

Changes of expectant mothers

Weight change

This month, expectant mothers began to gain weight, at least 2 kilograms, and some may reach 5 kilograms.

The enlargement of the uterus causes corresponding changes.

At this point, the expectant mother's uterus is already the size of the baby's head. When you touch the navel and pubic bone, you can feel a hard thing and the upper part of the uterus. The height and thickness of the uterine fundus are about 15~ 18 cm at the upper edge of the femoral joint. After the baby 19 weeks old, the uterine bottom of the expectant mother will rise 1 cm every week.

Because the uterus is gradually enlarged in the abdominal cavity this month, the symptoms of irritation to the bladder are reduced, so the phenomenon of frequent urination is relatively reduced, the early pregnancy reaction naturally disappears, and the expectant mother's body and mood will be much better.

At this stage, some expectant mothers will feel indigestion because of the accumulation of food in their stomachs, which is because the enlarged uterus squeezes the internal organs. In addition, some expectant mothers often feel thirsty, even tinnitus, and mistakenly think that they have a cold, but in fact it is not. This is mainly the internal change caused by pregnancy.

Breast changes

In this month, expectant mothers' breasts will swell more obviously than before, and some expectant mothers can squeeze out transparent, viscous and slightly white liquid with the same color as water. Moreover, the buttocks become round because of the increase of fat, and from the appearance, they begin to be fuller than before.

Fetal movement

From the end of the fifth month, when the expectant mother pays attention, especially when lying in bed at night, she will feel the lower abdomen crawling like a bug. Usually, babies squirm, stand in the amniotic fluid in the uterus, move their hands and feet frequently and collide with the uterine wall.

Now expectant mothers should insist on counting fetal movements regularly, and the time is best fixed. Fetal movements generally average 3 to 5 times per hour. It is direct prenatal education to insist on counting fetal movements every day. When expectant mothers are very concerned about their babies, they can imagine the baby's various postures, and the baby will respond to the mother's feelings, thus enhancing the emotional communication between mother and child.

After 5 months of pregnancy, fetal changes: 1. Heart development is almost complete, and most expectant mothers can feel fetal movement; 2. The development of brain tends to be perfect, and respiratory movement begins to appear; 3. Digestive organs begin to work, and sensory organs also develop rapidly; The appearance is getting better and better. Mothers should pay attention to calcium supplementation, vitamin A and vitamin E supplementation, at the same time, take good care of their breasts, prepare for breastfeeding, pay attention to maintaining oral hygiene and prevent gingivitis during pregnancy. Mothers can put on maternity clothes and take pictures of their bellies.

I am pregnant for five months, about 20 weeks; When pregnant women enter the second trimester, the fundus of uterus rises about 1 cm every week. The fetus is about 25 cm long and weighs about 320 grams. The fetus begins to swallow amniotic fluid, the kidneys can make urine, and the hair is growing. Sensory organs began to develop rapidly according to regions, and neurons were divided into different senses. From this time on, taste, smell, hearing, vision and touch all develop in special areas of the brain. The number of neurons slowed down, but the interconnection between neurons began to increase.

Fetal hair and subcutaneous fat began to form. The fetal heartbeat is very active, and the fetal hands and feet can move freely in amniotic fluid. The fetus has the function of swallowing and urinating, and the fetal heart sound can be heard when it is attached to the abdominal wall. Maternal changes: the early pregnancy reaction disappeared and the appetite recovered. The swelling of the waist and abdomen is more and more obvious, and the subcutaneous fat is thickened, so loose clothes must be worn. Pay attention to the fetal movement.
