From 7 to 9 weeks of pregnancy, there are many processes and transformations in the womb of the expectant mother. And, although a clear increase in the abdomen has not yet been observed, the development of the fetus is carried out at a fairly rapid pace: its weight is 7 grams, its height is 4 centimeters.

And by the 9th week, the baby already has all the makings of a future person (in terms of the body, internal systems and organs), only in miniature. All this is a real miracle that every expectant mother comes into contact with in her life.

What happens at the 9th week of pregnancy, what is the condition of the woman, her lifestyle diet, as well as the features of the previous 7th, 8th and subsequent 10th week, we will describe later in the article.

Description

Bearing a baby is a process in the body of a future mother, which lasts 36-38 calendar weeks (actual) or 40 obstetric (since there are only 28days).

It all starts from the moment of conception, when the sperm and egg meet, after which fertilization occurs. Further, the embryo, which is already beginning to divide into many cells, moves towards the uterus, where it attaches to its wall.

It is here that a whole stage of the intrauterine life of an infant begins and proceeds: the formation of the body and internal organs, all vital systems, and so on. And the process ends with the physical birth of the baby - after 9 calendar months or 280 days.

Intrauterine development is divided into three main stages:

1. Zygote or the period of the fetal egg - lasts up to 10 days, starting from the process of fusion of the sex cells of a man and a woman. And this stage ends at the moment of implantation of the embryo into the wall of the uterus. These days, the embryo fully adapts to the conditions and environment. The maintenance of his life support comes from the corpus luteum secreted by the ovary.
2. Embryonic - lasts 8 weeks, starting from the introduction of the embryo into the wall of the uterus. The most important period, since it is during these weeks that all systems and organs of the unborn baby (brain, heart, kidneys, blood vessels), as well as character and immunity, are fundamentally laid.



3. Fetal - duration of 28 calendar weeks, starting from the 9th and ending with the moment the little man is born. This is also a rather important stage, since all the organs and systems that were laid down before are developing.moment. And the child is actively gaining weight and growing physically, gradually preparing for birth and independent life (without the mother's umbilical cord and placenta). The child is already called a fetus.

All developmental processes occur naturally, and the quality and characteristics of mental and physical he alth depend on genetics, which is transmitted through the chromosomes of the father and mother.

About the trimesters of pregnancy

Just like the development of the fetus, which is divided into three stages, the entire process of pregnancy consists of three trimesters:

• 1-13 weeks;
• 14-27 week;
• 28 week - delivery.

Graduation may fluctuate a little, but on average each period lasts 13-14 calendar weeks.

In each of these stages, the most important changes take place both in the unborn child and in the woman.

Next, we will consider the characteristic features of the processes occurring during periods of the 9th obstetric (7 calendar) week, as well as 8, 9 and 10 calendar weeks.

And since this gestational age is the most favorable time for the expectant mother to register at the clinic, it is necessary to clarify what tests will be important to do.

9 obstetric or calendar week 7: what happens

The described period of pregnancy (and all previous weeks) is most often the most difficult for the expectant mother. There is a constant sharp change in mood, regular nausea in the mornings or late evenings, lack of appetite, excessive lethargy and a decrease in overall vitality.

But exactlyat the 9th obstetric week of pregnancy, a woman really begins to feel the first changes in her body, which openly indicate that a small creature has been born and develops in her - an unborn child:

• rounded figure;
• weight loss (not much, due to toxicosis and poor appetite);
• feels dizzy;
• stretch marks appear on the skin.

For a baby, this period of development is also quite critical. But now things are starting to get better. All these weeks, the nutrition and maintenance of the vital activity of the embryo was carried out at the expense of the corpus luteum, but soon this role will be taken over by the placenta, which completes the stage of its development. All conditions and a comfortable environment are created for the baby so that he develops and lives his intrauterine life as well as possible.

At the 9th obstetric week, new organs are intensively formed, as well as the internal systems of the unborn child. In the foreseeable future, it will already be called a fetus and will take on the shape of a miniature baby.

Its dimensions are quite small - 2.5 centimeters in length and 3 grams in weight. If compared with images that are understandable to human perception, then the baby would fit in an olive or a large grape.

The brain is developing intensively: both hemispheres are already distinguishable and the cerebellum begins to form. The central nervous system is also being built, including cranial, spinal and intervertebral nerves, nerve nodes.

During this period of development of the unborn baby, the pituitary gland, bronchi, genitals, bloodvessels.

Movements become more coordinated and frequent. The child begins to explore the entire area in which he is.

What is typical for 8 weeks

On the eve of the 9th - at the 8th week of pregnancy - there are also unpleasant moments with the well-being and mood of the expectant mother. The reason for this is the fluctuations in hormonal levels in a woman's body.

She is recommended to load herself less, rest more, walk in the fresh air. If the expectant mother is studying or working, then during this period you can ask for a vacation for a few days.

As for the development of the baby, his weight is growing very intensively, and the length is increasing by 1 millimeter per day. And is 3.5 grams and 3 centimeters.

The embryo is now called a fetus. His tail fell off. Small fingers appeared on the arms and legs, between which a thin membrane is still preserved. He flexes and extends his elbows and knees, and his lungs are actively developing.

This period also falls into the first trimester. What is happening, and why is this stage remarkable for mother and child?

It is from this moment that the development of the fetus enters a new phase - the fetal period. This is a very interesting and special time of pregnancy. What happens to the baby at week 9, we list further:

• The child is already starting to move and move quite actively, as bones, joints, cartilage and muscles have begun to develop intensively. The fetus turns over and toucheswalls of the placenta.
• His movements are not yet noticeable, since the size and weight of the baby are very tiny - 4 centimeters and 7 grams, respectively.
• The endocrine system and the brain continue to develop (the cerebellum is formed). The adrenal glands are already producing hormones.
• And there is also the formation of cartilaginous tissues of the vocal cords, ears and larynx. The swallowing reflex comes into play (this is already noticeable during an ultrasound examination).
• As for the position of the baby, he sits with his knees tightly tucked in, which rests on his chin. The head and torso are already clearly visible. Fingers, including thumbs, appear on elongated handles.
• In general, at the 9th week of pregnancy, the development of the fetus, as well as its growth, is 2 times faster than before.
• Improves blood circulation in the vessels of the placenta, which becomes a real protective barrier for the fetus. It protects him from external influences (noise, injuries) and the ingress of unnecessary substances (medicines or alcohol, but in small quantities).

Psychological state of a woman at 9 weeks

During this period of pregnancy, the internal state, and, accordingly, the mood of the expectant mother can fluctuate from positive to negative and vice versa. Of course, this is not the easiest time for a husband and other relatives of a woman, but soon it will pass, the mood will become more stable and benevolent.

Also, internal anxiety may appear, worry about the future of the child, the process of bearing in the remainingmonths and childbirth. And a huge feeling of loneliness and abandonment can accompany a woman during this period.

All this is normal and natural for a future mother, she just needs a little more attention and care from the closest people. And the woman herself - patience and faith only in the best outcome of the whole thing. After all, the long-awaited baby will appear very soon!

The state of the body at this time

What happens to mom at 9 weeks pregnant yet:

1. Toxemia, excessive sensitivity of the nipples, dizziness and high fatigue level stop.
2. There are noticeable changes in the state of he alth: metabolic processes increase (by 25%!), the kidneys begin to function even faster (since these organs of the baby have already started working as well, but all the fluid leaves through the woman's body), an increase in the volume of circulating blood.
3. Intense sweating and internal heat may occur, as well as cramps, heartburn, sore gums, constipation, and lower back pain.
4. During this period, it is recommended to drink more clean water, eat plenty of fruits and vegetables, and reduce the consumption of s alt and spices in main dishes. All this is to ensure that the liquid is well and timely excreted by the body, otherwise swelling and problems with urination may appear.
5. During 9 weeks from the moment of conception, vaginal discharge can be quite intense, but light, with a sour smell.
6. Stop all pain in the lower abdomen. Colostrum may appear and gradually exit until birthchild. By the way, it is strictly forbidden to squeeze it out. If the liquid stains the bra, then you can purchase special pads for this.

If there are any negative deviations from the norm, and at the 9th week of pregnancy the stomach hurts, the discharge has an unpleasant odor and a strange consistency, then you need to consult a doctor.

What will the 10 calendar week of pregnancy bring?

In general, after the 9th week has passed and the 10th week comes, there are no cardinal changes, but all the same organs and systems that appeared earlier continue to develop and improve.

During this period, a woman fully realizes that she will soon become a mother. This is also evidenced by a small tummy, slightly hanging over the bosom, and some inconvenience with clothing and sleep.

At 9-10 weeks of pregnancy, a woman is already sent for an ultrasound examination to determine the exact date, as well as the correct development of the fetus, listening to the heart (normally about 150 beats per minute).

Baby's skin is still transparent. Through it, internal organs are visible. And his whole appearance is slightly blurred. But his movements and movements in the womb are quite well traced.

Lifestyle and diet for 9 weeks

Due to the fact that toxicosis in most women has stopped, appetite begins to appear. In this case, the rejection of certain foods or strange taste preferences may persist for the entire duration of pregnancy.

Recommended frequent meals (up to 6 times a day)day) - in small portions. Between them, you can drink compotes, juices, water, and also eat fresh fruits (locally grown).

There is no need to include too intricate or exotic dishes in the diet, the simplest and he althiest food will be the best: buckwheat, boiled dietary meat, fresh seasonal vegetables.

Approximately in the first trimester, the expectant mother consumes 2000 kilocalories per day. All this is necessary for the baby, since all the most important organs are being formed.

Together with food, it is important that proteins, vitamins, and microelements enter the body of a woman. To do this, you need to harmoniously distribute products throughout the day:

• drink 200 milliliters of water before breakfast;
• prepare breakfast from meat or fish ingredients, eggs, vegetables, porridge;
• lunch - meat or fish, first, porridge, fruit;
• dinner - milk dishes, fruits, cookies.

In order for a woman to feel normal at night and get up easily in the morning, it is important to eat the last meal at least 2 hours before going to bed.

For constipation, it is recommended to include prunes, kefir, beets, vegetable products with fiber in the diet.

And at work, you need to ask the manager (subject to hired labor, harmful conditions, and so on) to provide a more loyal schedule and acceptable workload. Still, the life, he alth and safety of the baby is more important than anything else - career, money, opinions of people around.

Registration

It is at the stage of 7-10 weeks of pregnancy that most women become registered inantenatal clinic of the district polyclinic. This allows you to be under the supervision of medical personnel for the entire period, as well as undergo all the necessary procedures: ultrasound, tests, and so on.

Why is it important to register early:

1. In the first weeks, the foundations for the development of the unborn child are formed, and therefore the expectant mother needs to be aware of her situation and not abuse junk food, chemicals, overexertion at work.
2. It is important to start drinking vitamin complexes that the doctor prescribes based on the results of the analysis.
3. During pregnancy, chronic diseases can worsen, and therefore it is recommended to live this time under the supervision of a qualified doctor.
4. In the territory of the Russian Federation, every expectant mother who registers before 12 weeks receives monetary compensation (subject to official employment).

Tests and other procedures

During registration, the doctor prescribes the following mandatory procedures for the pregnant woman:

• full inspection;
• general blood and urine tests;
• blood clotting test;
• blood typing, Rh factor;
• dab;
• biochemical screening;
• measuring heart rate and blood pressure;
• ultrasound;
• measuring the width of the pelvic bones, as well as the height and weight of the expectant mother.

During the 9th week of pregnancy (you can see a photo of the ultrasound of the fetus in the article), the expectant mother is prescribedexamination on an ultrasound machine to determine the size, approximate weight, development of the organs and heart of the child. Thus, both the term of the interesting position and the approximate date of birth are confirmed.

CV

In general, the stomach at the 9th week of pregnancy is still invisible, and therefore this is only the beginning. And all the most important, interesting, joyful things in a woman's life are ahead.

It is important for a future mother to take care of herself, take care of her psychological and physical he alth, feel free to ask for help from her relatives, manager and colleagues. And she just becomes happy from the realization of her upcoming great mission - to be a mother.
