• The first move, too sensitive women, can feel at 12 weeks of pregnancy. But they are also easy to confuse them with the movement of gases through the intestines. These are unforgettable and indescribable sensations
• If the pregnancy is not the first, already the real first shocks, the mother will feel at 15 weeks. Pregnant firstborn was less fortunate, they should be patient up to 20 weeks

Important: from that moment on, the mother feels a special connection with her baby.

In more detail, the first ultrasound of the study and the development of the fetus can be found from this article: Ultrasound during pregnancy: indications, terms, fetal development norms. 

Fetal weight by week of pregnancy

The weight of the fetus can be traced with ultrasound. This is a very important criterion for determining anomalies in the development of the future baby. At the very beginning of its development, it does not weigh even 1 gram. All data in the table are approximate, and may have minor deviations.

• 4 weeks:  0.5 grams
• 5 week: 0.8 grams
• 6 week: 0.9 grams
• 7 week: 1 gram
• 8 week: 1.5 grams
• 9 week: 2 grams
• 10 week: 4 grams
• 11 week: 8 grams
• 12 week: 14 grams

Fruit development standards for weeks

Of great importance I have indicators of the growth and development of the baby in the womb. Comparing them with the indicators of the norm, the doctor can reveal pathologies or development in time in time. Also, according to these data, you can determine the gestational age. It is very important not to miss all the planned visits to a specialist and examination.

The size of the fetus in weeks in comparison with seeds, fruits

In order to imagine what size the fetus is at the beginning of pregnancy, you can compare it with seeds, vegetables and fruits:

• 4 weeks: poppy grain
• 5 week: sesame seed
• 6 week: peppercorn
• 7 week: beans
• 8 week: grapes
• 9 week: cherry
• 10 week: strawberries
• 11 week: lime
• 12 week: lemon

Fruit length in weeks

At the very beginning of development, the fetus is very small, not more than 1 mm long, but it grows rapidly and develops.

• 4 weeks: 1 mm
• 5 week: 1.5 mm
• 6 week: 4 mm
• 7 week: 13 mm
• 8 week: 20 mm
• 9 week: 30 mm
• 10 week: 42 mm
• 11 week: 60 mm
• 12 week: 61 mm

The values \u200b\u200bare approximate and can fluctuate in one direction or another.

The weight of the child in size of the abdomen

You can determine the weight of the child by Ultrasound research, as well as in size of the mother’s abdomen.

• It should be measured, at the level of the navel, the circumference of the abdomen
• Know the height of the bottom of the uterus
• Multiply these two values \u200b\u200bby each other

This is the simplest way. Thus, you can find out the alleged weight of the child, but only after 35 weeks of pregnancy. The error is 200 grams.

Fruit head circumference by week

The circumference of the head is determined on planned ultrasound. They begin to measure it in the second trimester from 14 weeks of pregnancy. This value plays a large role in assessing the development of the baby.

Fruit heartbeat by week

Almost from the very moment of conception, the baby begins to beat the heart. At the beginning of its development, these are almost inaudible reductions. From the 7th week, you can see how the fetal heart is beaten with the help Ultrasound. It is according to the heart rate, an experienced doctor, can set the period of pregnancy and what gender the future baby will be.

• Until 6 weeks, the heart beats no more than 80 beats per minute
• From 6 to 8 weeks, its rhythm accelerates to 159 beats
• At 9 weeks even faster, from 170 to 190 beats
• From 10 - 11 weeks, the heart rhythm is already normalized and is 165 beats
• From 14 weeks, to the very birth, the heart rate is 157 beats per minute

The rate of the fetal heartbeat by week

The norms of the fetal heartbeat are very important for the diagnosis of any developmental deviations. They can also signal hypoxia.

If a woman has two eggs and their fertilization has ripened, then a multiple pregnancy occurs.

• 1 - 12 week:Toxicosis occurs a little earlier than during pregnancy with one baby. You can accurately determine the pregnancy with doubles with an ultrasound of the equipment. During this time, kids develop and attach to the uterine cavity. This period is very important, since the risk of miscarriage doubles

Important: up to about 12 weeks, one embryo may stop developing and freezing. This will not affect the further development of the second baby.

Video: How is the pregnancy twice?

Abdominal

In the first weeks of pregnancy, the fetus is very spacious in my mother’s stomach. He can constantly change his position. Only in the third trimester the baby will take its main presentation.

The cerebellum of the fetus

Important: the cerebellum is responsible for the motor activity of the future baby, the development of internal organs. During the ultrasound, starting from 14 weeks, closely observe its development.

Fruit increase

The baby is growing rapidly and developing. At the very beginning of pregnancy, weight gain is insignificant. From 8 to 12 weeks  the fetus gains from 1 to 10 grams every week. A little later, he will quickly begin to prepare for the publication.
