First and second weeks: Because ovulation usually occurs on the first14th day of the menstrual cycle, if menstruation does not come on time after two weeks, you may be pregnant.

Week 3: In the third week, you may find that your menstruation is delayed, or there is a small amount of blood flowing out of your lower body. At this time, you can go to the hospital or do a pregnancy urine test yourself. If the result is positive, congratulations, you are pregnant.

Week 4: People are in this week, and the blastocyst is called embryonic tooth at this time. It is like the seed of an apple in the womb. Embryonic cells develop rapidly. At this time, they have three layers, called three germ layers.

Week 5: At this time, the embryo is about 0.6 cm long, like a small apple seed. Cells divide rapidly, forming primitive neural tubes, and all germ layers continue to differentiate. Major organs such as kidneys and liver spoils begin to grow, and the heart begins to beat regularly and start to supply blood.

Week 6: At this time, the embryo is about 0.5 cm long and shaped like a tadpole. From this week, pregnant women can properly supplement folic acid to reduce the occurrence of cleft lip and cleft palate.

Week 7: At this time, the embryo is about 1.2 cm long and shaped like a broad bean. Pregnancy reaction intensifies, and this situation will last for 6 weeks or more.

Week 8: At the eighth week of pregnancy, the embryo grows rapidly. At this time, the embryo is about 2 cm long and shaped like a grape. Pregnant women are extremely tired and sleepy.

Week 9: Congratulations, since the ninth week, the embryo can be called a fetus, and he (she) is your real baby.

Week 10: At the first 10 week of pregnancy, the fetus can reach 4 cm in length and is shaped like a flat pod. At this time, the baby's wrists and ankles are fully developed and clearly visible. The baby's arms are longer and the elbows are more curved. The eyelids of the fetus are glued together.

Week 11: The fetal body is 45-63mm long and weighs14g. The fetus can start sucking, swallowing and kicking. Now the fetal subtleties have begun to develop, and his or her fingernails and fluffy hair have begun to appear.

Week 13: 13 The face of the fetus looks more like an adult, with a length of about 75-90 mm and a slight increase in weight compared with last week. His (her) eyes are more prominent on the forehead of his head, and fingerprints appear on his fingers.

Fourteenth week: 14 weeks, the face of the fetus looks more like an adult, with a length of about 75- 100 mm and a weight of 28 grams. At this time, the fetus grows very fast. Now the baby's skin is covered with a layer of fine fluff, which will disappear after the baby is born.

Fifteenth week: The fetus at 15 weeks is about12cm in length and weighs 50g. The biggest thing that happened to the baby this week is that he (she) began to burp in your uterus, which is a precursor for the fetus to start breathing.

Sixteenth week: The fetus at 16 weeks is about12cm in length, and its weight increases to150g. At this time, the fetus looks like a pear. The biggest thing that happened to the baby this week is that he (she) will play in your womb by himself.

Week 17: The fetus at 17 weeks is about13cm in length and150-200g in weight. The fetus looks like a pear at this time. At this time, the baby's bones are still cartilage, and the "lecithin" that can protect the bones begins to slowly cover the bone marrow.

Week 18: The fetus at 18 weeks is about 14 cm in length and weighs about 200 grams. At this time, the fetus's small breasts are bulging, which means that he or she is breathing, but at this time, the fetus inhales and exhales amniotic fluid instead of air.

The 19th week: 19 weeks, the biggest change of the baby is that the sensory organs begin to develop rapidly according to the region. Taste, smell, touch, vision and hearing develop in special areas of the brain from now on.

Week 20: At week 20, the fetal growth tends to be stable. At this time, you need to put more energy into enhancing nutrition.

Week 21: The fetus at 2 1 week is now about18cm in length and weighs 300-350g. At this time, the fetal weight begins to increase substantially. The baby's eyebrows and eyelids are clearly visible, and the fingers and toes begin to grow fingernails.

Week 22: The 22-week-old fetus is now about 19~22 cm in length and weighs 350~400 grams. At this time, the fetal weight has started to increase greatly, and it already looks like a baby. The eye has developed, but the iris (the colored part of the eye) still lacks color, and the eyebrows and eyelids are clearly distinguishable. His pancreas (an important organ that produces hormones) is also developing steadily. The baby's lips are getting clearer and clearer, and the small cusp also appears in the gum, showing the first signs of teething.

Twenty-third week: The 23-week-old fetus is now about 19 cm long and weighs about 400 grams. At the age of 23 weeks, pregnant women are getting heavier and heavier, and they are growing rapidly at a rate of about 250 grams per week. Because the uterus is getting higher and higher, it compresses the lungs.

Week 24: The 24-week-old fetus is now about 25 centimeters long and weighs more than 500 grams. At this time, the baby occupied a considerable space in the mother's uterus and began to fill the whole space.

Week 25: The 25-week-old fetus is now about 30 cm long and weighs about 600 grams. The pregnant woman is still moving freely and does not have to walk unsteadily.

Week 26: The fetus at 26 weeks is now about 22 cm tall and weighs about 800 grams. The baby's subcutaneous fat has begun to appear, but at this time the baby is still very thin, covered with fine villi, and the 26-week-old fetus begins to breathe.

Week 27: The 27-week-old fetus now weighs about 900 grams and is about 38 centimeters long. You can see that short fetal hair has grown on the fetal head. At this time, the auditory nervous system of the fetus has also been fully developed, and its response to external sound stimulation is more obvious.

Week 28: From the 28th week, you enter the third trimester. There are many things to pay attention to! During this time, you should try to reduce the chances of traveling, because many airlines do not accept pregnant women who are pregnant for 28 weeks to fly.

Week 29: The 29-week-old fetus now sits about 26-27 cm high and weighs about 1300 g. At this time, if the baby is a boy, his testicles have come down from the abdomen; If it is a girl, you can see the baby's protruding labia minora.

Week 30: The 30-week-old fetus is now about 44cm tall and weighs about1500g. The fetus continues to grow in the head and the brain develops very rapidly. The brain and nervous system have developed to a certain extent, and subcutaneous fat continues to grow.

Thirty-first week: At 3 1 week, the fetal body and limbs continue to grow up until the proportion is equal. The fetus now weighs about 2000 grams. The baby's subcutaneous fat is richer and wrinkles are reduced.

Thirty-second week: The fetus at 32 weeks is about 40 cm in length, 28 cm in top and hip length (sitting height) and about 1.5~ 1.6 kg in weight. Today's fetus is similar to the baby at birth, but the body still needs to gain weight. His fingernails and toenails have completely grown out. Some babies have grown a full head of hair, and some have only grown faint fluff. His eyes can distinguish between light and darkness. If the baby is a boy, his testicles may have entered the scrotum from the abdominal cavity, but some babies may not enter the scrotum until the day after birth.

Parenting network experts pointed out that the length and weight of the fetus will gradually increase with the month of pregnancy. In order to facilitate memory, the following formula is generally used to calculate:

Body length before 20 weeks of pregnancy = the square of months of pregnancy (cm); Body weight = cubic ×2(g) of pregnancy months.

Body length after 20 weeks of pregnancy = months of pregnancy ×5(cm); Weight = cubic× 3 (g) of pregnancy months.

Thirty-third week: The fetus at 33 weeks is about 48 cm long and weighs about 2200 grams. The development of the respiratory system and digestive system of the fetus is close to maturity, and the fetus should pay attention to the position of its head at 33 weeks.

Week 34: The fetus at 34 weeks sits about 30 cm high and weighs about 2300 grams. The fetus is getting fatter now. The subcutaneous fat of the fetus will regulate the body temperature after the baby is born. At the same time, the baby is also preparing for delivery. The baby's head turns downward and the head enters the pelvis.

Week 35: At this time, the fetus is about 50 cm long and weighs about 2500 grams. The fetus is getting fatter now. The subcutaneous fat of the fetus will regulate the body temperature after the baby is born.

Thirty-sixth week: The fetus at 36 weeks weighs about 2.7 kg and is about 45~50 cm long. The fluff covering the baby's whole body and the fetal fat protecting the baby's skin in amniotic fluid are beginning to fall off. The baby can now swallow these fallen substances and other secretions.

In the first 10 month, pregnant women will feel very nervous, agitated and anxious in the last month, and at the same time, pregnant women will feel heavier and heavier in these weeks. Pay attention to careful activities, avoid standing for a long time, and avoid slipping in the shower. In short, have a good rest, pay close attention to your physical changes, and be ready for labor at any time.

In the second week of ten months' pregnancy, your fetus may have weighed 3200 grams and its length must be about 50 centimeters. The fetal head swings in your pelvic cavity, surrounded by the pelvic skeleton, which is very safe. This also frees up more places to grow his little arms, calves and little ass. Many fetuses have grown a lot of hair at this time, about1-3 cm long. If one of the parents has curly hair, your fetus is probably a small curly head.

In the third week of ten months' pregnancy, the average weight of boys is slightly heavier than that of girls. The fetus continues to gain weight now, and these fat reserves will help the baby's body temperature regulation after birth. This little guy's body organs have been developed, among which the lung is the last mature organ, and he can only establish a normal breathing pattern within a few hours after the baby is born.

If it is a mommy friend who chooses to give birth naturally. Don't go out for a walk alone when the labor is approaching, because at this special stage, you are likely to encounter unexpected joy-the baby is born early. Under normal circumstances, only when contractions begin and the cervix expands, the egg membrane wrapped around the fetus and amniotic fluid will rupture under increasing pressure, and a large amount of amniotic fluid will flow out, and the fetus will be born.

Changes of fetal position during pregnancy Figure 2 Where is the fetus in the stomach after three months of pregnancy?

1, because under normal circumstances, sperm and eggs will meet in the fallopian tube, and then swim back to the pregnant mother's uterus through the fertilized egg, and then further settle down and grow slowly. Therefore, as long as it is a normal pregnant embryo, the fetus at the back will live in the pregnant mother's womb.

2, the female uterus is deeply hidden in the pelvis, and the normal size uterus is only as big as a pear, which is basically invisible from the stomach. By the third month of pregnancy, the fetus is about a few centimeters long, and the uterus begins to get bigger, but it is just a little beyond the pelvis. The thinner one can touch a little above the pubic symphysis; A pregnant mother with a little meat still can't touch her uterus.

How old is the baby who is pregnant for three months?

Three months pregnant, at this time, the fetal head accounts for about half of the body length, and the activities of the fetal hands and feet can be seen through B-ultrasound. The knees and heels of the fetus are also clearly visible. The kidneys and ureters have been formed and can be basically excreted. The fetus is busy moving, from tooth germ to toenail, sometimes kicking and sometimes stretching, which looks like ballet in diving.

Great changes have taken place in the fetus in the past three months. At this time, the fetus can swim in the amniotic fluid, but it is not very flexible. The development of fetal internal organs has been basically completed, and the fetus absorbs growth nutrients through the umbilical cord. After the kidney is formed, urine can be discharged into amniotic fluid. The facial contour of the fetus is becoming more and more distinct, and eyelids, eyebrows, ears, lips and nostrils are also being formed one after another.

Babies all grow in the uterine cavity, and those who grow outside the uterus are ectopic pregnancy, so mothers should be alert to ectopic pregnancy, and do B-ultrasound examination in the early stage of early pregnancy to confirm that the gestational sac grows in the uterine cavity to avoid ectopic pregnancy. I wish you healthy growth.

Fetal position changes during pregnancy Figure 3 Fetal position after six months of pregnancy

In fact, because there is a lot of amniotic fluid in six months of pregnancy, it is sometimes difficult to judge the position of the fetus, because the fetus is still "swimming" very happily at this time. However, the length of the expectant mother's uterus is 18 to 2 1 cm. The hair of the fetus will thicken, eyebrows and eyelashes will begin to grow, and the subcutaneous fat of the fetus will increase by about 250 grams per week.

With the increasing number of sheep, the fetus in the uterus can change its position freely, and then the expectant mother can feel that the fetal activity is more frequent. For expectant mothers, their abdomen is getting bigger and bigger, which is close to the body shape when they are going to give birth, but if the abdomen is too big, they should start to pay attention to a balanced diet.

The fetal position is not correct after six months of pregnancy.

Some pregnant mothers may find that the fetus at this time is a little abnormal during pregnancy examination. In fact, there is no need to worry too much about this situation, because before the 28th week of pregnancy, the fetal position will still change at any time until the 32nd week.

Therefore, expectant mothers who are pregnant for six months with abnormal fetal position do not need to worry too much, because the space for fetal activity is relatively large, and the fetal position will change. Just continue to do a good job in pregnancy examination. In general, the incidence of fetal malposition dropped to 8.8% at eight months, and only about 5% of fetuses were diagnosed with fetal malposition at nine months.

However, if the fetal position has not been corrected in the thirty-second week of pregnancy, it is necessary to carry out fetal position correction measures at this time. If the fetal position is not correct, you can use chest and knee horizontal. First of all, expectant mothers need to urinate, relax their belts, kneel on a hard bed covered with cotton wool, straighten their forearms, keep their breasts as close as possible to the bed, tilt their hips up, and make thighs and calves at right angles. Do this twice a day for 3-5 minutes at first, and then increase it to 10- 15 minutes each time.

However, on the whole, after paying attention to the balance of diet and nutrition intake during the sixth month of pregnancy and taking necessary exercise, some accidents can be avoided. Expectant mothers can also start prenatal education at this stage, because the fetal auditory system is formed during this period.
