The age of the embryo itself is 3 weeks. This is an important stage in your baby's life! It is from 5 weeks that doctors begin to refer to his embryo. In the structure of the embryo, significant changes occur: in shape it is now rather reminiscent of a cylinder with a length of 1.5-2.5 mm.
The cells of the body of the embryo continue to be actively divided, and the most important event of the fifth week of pregnancy is the separation of tissues. The laws of evolution are such that the most important fabrics and organs are formed first.
The headband of the embryo is growing faster than the tail, which, together with the area of the primary tuberca, as if retreats backwards. At the end of this week, the Kepened from the primary tubercle in the outer germs, the longitudinal strip of actively growing cells is distinguished - the nerve plate. This plate will soon be defeated, forming a longitudinal furrow - a nervous groove. For the next weeks, as the grooves are deepened, its edges thicken, bring together and grow together with each other, closing the nerve groove into the nervous tube. In the future, the entire nervous system is developing from the nervous tube.
Begins to form a placenta - the system of life support of the embryo. Trofoblast and part of the ectoderma form Amnion and Chorion. Amnion in the people called "shirt." In the amniotic cavity are accumulating waters. Chorion is a vigorous formation, which also produces chorionic gonadotropin. After a while, with the participation of Mesoderm from Chorion, a placenta is formed. Containing blood vessels, connecting the embryo with off-facilities (placenta), forms the abdominal skeleton. By the end of 3 embryo or 5 obstetric week, the embryo will grow up to 4 mm sizes.
5 week of pregnancy - significant in terms of fetal development. It weighs only 3.5 g and looks like a rolled arc tube long 4-7 mm, but not only the head and tail, but the rest of the body and organs are already visible: the rest of the hands, legs, fingers, eye, oral and nasal gap are evaporated , Own shells, begin to form upper respiratory tract, liver and pancreas.
On 5 week, partial closure of the nervous tube occurs, from which the spine, the dorsal and brain will be formed and the entire central nervous system. This contributes to the intake of the mother of folic acid. It is very important during this period to protect against stresses, each experience can affect the baby. For 20-22 days after conception, just this week, a small primitive heart makes his first blows.
The first blood vessels of the embryo are formed, and it is surrounded by amniotic fluid: from 5 weeks the metabolism between the mother and the future child is being established, now you are fully responsible for it, and it is entirely depends on you, your nutrition, Mooding, actions.
I wonder what now you can determine the blood group of the fetus. And at another 5 week of pregnancy, sex glands, eggs and spermatozoa are formed - the floor of the future child was defined at the time of conception.
From this week, it begins to significantly increase in the sizes of the uterus, although it is not yet visible. Now it resembles an egg in shape and can be merged from the side of the fetal egg, that is, it increases asymmetrically. Gradually, it will become spherical from the extended. At 5 week, the uterus has already increased enough so that an experienced gynecologist could determine these changes to the touch and assume the development of pregnancy.
To accurately set the size of the uterus and confirm the "diagnosis" will be able to the 5th week of pregnancy. At this time, you already affect how much fruit develops inside you, where they attached, and also appreciate the state of the uterus and, if necessary, will make the necessary forecasts. At 5 week of pregnancy during an ultrasound, a good specialist in good equipment can already listen to the first heart rhythms of the embryo - more likely closer to the end of 5 weeks. This indicator, together with the motor activity of the fetus, uzper will use to assess the life of the baby.
On 5 week of pregnancy, ultrasound will not show the estimated weight of the child nor other parameters. Instead, the feed diameter of the fruit bubble is measured and the CTR is a cochico-dark size, that is, the length of the embryo from the temperature to the tailbone. It is such a "growth" of the fetus will be indicated during the first 20 weeks of pregnancy, and after it will begin to measure in full growth - from the pavement to heels.
Increasing the uterus begins to put pressure on the bladder, so with 5 weeks of pregnancy you will start running into the toilet more often. This symptom, along with other signs, can push a woman to the idea of likely pregnancy. Yes, and monthly, it seems, how long had to begin . And then the chest hurts, and the stomach, and nausea it became somehow stronger, and also smells all such sharp .
At the 5th week of pregnancy, taste addictions can change, to increase or disappear appetite, often begins to show itself toxicosis, including those started by vomiting - hormones are actively working.
5 weeks of pregnancy: for the future mother it is a time when suspicion is most often appeared, and even confidence about the start of the nose. Menstruation delay, the first positive results on the test signals the changed position. How it turns out that only 2 weeks passed from conception, the pregnancy is only confirmed (or not yet), and the term is for more than a month? What can recognize a woman about himself, what does it feel, and how is the embryo? We answer all questions.
Obsters consider pregnancy not from the moment of conception (it is impossible to know about it outside the reproductive technologies), but from the first day of the last menstruation. This is the most reliable and convenient way to calculate the period of gestation.
The fifth week of pregnancy on average from conception takes 10-14 days with a stable menstrual cycle. Since the averaged and "right" is considered a cycle length of 28 days, which is similar to the period of circulation of the moon around the Earth (precisely with tides and casting water, as scientists suggest, the cyclicality of the female body is connected, since our ancestors lived in aquatic environment), So the pregnancy is calculated. Although according to the latest studies, exactly 28 days, the menstrual cycle is as a maximum of one of 10 girls and women of childbearing age. But we consider the periods of gestation.
Modernochine is easy to use and reliable enough. Among all the options are allocated two main: submersible and jet. Immerseddo omitted in a clean capacity with freshly placed, preferably the first morning urine, and the inkjet tests can be held for a few seconds under the urine bus, without looking for a jar for analysis.
Due to the increased sensitivity of the reagent, the inkjet tests show the result after the minimum contact time with the urine and do not require morning liquid collection. The same feature allows them to be used even before the start of the menstruation delay. But if you want to hold a similar pregnancy test to the fifth week, the cycle is 26-28, it is still used to determine the morning urine, the first portion.
The reason is that the human chorionic gonadotropin in the right concentration in the blood of the woman does not accumulate immediately after conception. It begins to stand out after implantation of an egg cell, and up to this point after intercourse may pass 5-8 days, and sometimes somewhat longer. A few days will need to achieve the concentration of hormone hgch, which will respond a pregnancy test.
In gynecological practice, an obstetric method of counting is used - the term of pregnancy is calculated from the first day of the last menstruation. The embryonic method has discrepancies with the obstetric technique in 2 weeks, and considers the term of pregnancy from the date of ovulation, from about the middle of the cycle.
If we take into account all these techniques, the fifth week of conception is equal to the seventh obstetrician week of pregnancy. The fifth week from the date of the menstruation delay is equal to the ninth week in the obstetric technique. Below, the information for the most part is focused on the medical point of view.
True, these parts of the body are still difficult to recognizable. Where the ears will appear in the future, now the usual fossa. But under it already there is an inner ear looking like snail. Future hands and legs on this period are called kidneys who tend to intensive growth.
It looks bent in the arc tube, the length of which is barely reaching 5-7 mm. Inside a small organism begins the formation of spleen, liver, gender glands, upper respiratory tract. The nervous tube is gradually closed, a full nervous system is laid: a dorsal, brain, vertebral pole.
In the ensuing functioning of the body of the internal secretion - the thyroid gland. Erythrocytes begin to synthesize, it becomes possible to determine the blood group. Since the fruit grows, the need for metabolism with the mother's body appears. The child begins to study it intensively. A placenta is formed through which the fetus receives nutrients and oxygen, and removes products of their livelihoods.
The development of fruits with twins proceeds similarly to one-way. Each future kid weighs on average 2 g. The length of it barely reaches a one and a half-two mm. However, with ultrasound, you can already distinguish the head part, tiny fighters of the limbs: the handles and legs. An experienced specialist is able to distinguish the eye recesses. The fundamental processes are:
The formation of the placenta can go on two ways: with a variacy double - for each embryo is isolated, with one-way - placenta one. Two children's places are more often located in close proximity to each other, so they often look in the ultrasound.
The gradual growth of the uterus initiates its pressure on the bladder, from which frequent urinary urges. Pains in the abdomen, in breast glands, with swelling and darkening of nipples are added to the absence of menstruation. Frections of nausea, vomiting, can be a periodic loss of knowledge. The flavoring sensations change, irritability and federation appear.
12 days ago Your egg fertilized spermatozoa, the process of cell division, four days, instead of one cell, have 58, while directly the fruit consists of 5, and the remaining cells are needed for its power.
On the 5th week, the placenta does not yet protect the baby in full force, it is only formed and looks like a bubble filled with liquid. But with each week it will compact and execute both protective and nutritional functions.
There are two options for developing events. It may be that a woman absolutely does not feel changes in its body and the possible pregnancy will learn due to the lack of menstruation, although, in isolated cases, the pregnancy has come, and the period is still regular.
With this scenario, pregnant recognizes about his interesting position at the doctor's reception, and the usual signs of pregnancy for 5 weeks are completely absent. Read article on this issue: >>>
For medical standards, 5 weeks from conception is considered to be the 7th obstetric week. A pregnancy test with a sensitivity of 25 MME / ml will already show the result with the sign "+" due to the high concentration in the blood of the HCG - the hormone of pregnancy.
Note! Light allocations from the vagina on this week may manifest intensively. This is the result of an intense inflow of blood to the growing female organ - the uterus. It is not worth worrying, so the body of pregnant responds to everything that happens inside. For Mom and her crumbs in the womb, these changes are not hazardous.
This week takes the beginning of the embryonic period of the child's intrauterine development. Together with him, the first critical period of pregnancy comes into force, the formation of the internal bodies of the future baby is beginning: intestines, urinary tract, kidneys, liver. Cardiovascular system of fetal and brain is developing and improved. The 35th day of the intrauterine life form nasal processes, the mouth cavity and the upper lip. The embryo at this time is especially vulnerable to the action of adverse factors - infections, toxins and hormonal disorders of the parent organism.

First of all, it is worth recalling that five obstetric weeks is a period corresponding to the third week of the development of the embryo. That is, by this time there were twenty-one days after conception. During this time, the fetal egg was fastened in the uterus and the fruit has already managed to grow noticeably. Now its size is comparable with the size of the rice grain. However, 5 weeks of pregnancy is not the time when the position of the woman becomes obvious, from the side explicit signs of pregnancy, invisible.
At the beginning of pregnancy, the fruit grows literally "not by day, but by the hour." On the fifth week, he has already managed to turn from a spherical fetal egg to the embryo, reminding his appearance of the headstuff.
