Colady magazine pregnancy expert. Mother of three children, obstetrician by training, writer by vocation.
Share with your friends and rate the article:This calendar is compiled based on the actual period of pregnancy, that is, from conception. The obstetric deadline, the one set by gynecologists, is 2 weeks ahead of the real one. Take this into account.
In the first week of pregnancy, the fusion of the egg and sperm occurs, forming a zygote, from which the chorion (placenta) and embryo (unborn child) will subsequently form. At conception, the sex of the baby is determined.
The second week of the baby’s life is marked by the fact that the zygote finds a place in the woman’s body where it will develop. Implanted into the wall of the uterus or other organ (then it occurs ectopic pregnancy). Chorionic gonadotropin (hCG) is determined in a woman’s urine and blood.
In the third week, pregnancy tests “strip” and the woman begins to experience delayed menstruation and toxicosis. On an ultrasound, most likely, the fertilized egg will not be seen yet, it is too small. But signs of pregnancy are already appearing. And a very tiny embryo begins its development. His body and head are clearly defined.
At the 4th week, the length of the embryo is 2-4 mm, and the fertilized egg is about 1 cm or a little more. They are clearly visible on good ultrasound equipment. If everything is normal, the fertilized egg has an even shape. If there is a detachment of the ovum, the doctor poses a threat spontaneous miscarriage. Most often, pregnancies are terminated at this stage due to severe chromosomal abnormalities of the fetus.
In the fifth week, the fetal heart begins to beat, and it is its beats that are the main evidence that the pregnancy is developing. It's time to register with a gynecologist and be sure to read the calendar by week of pregnancy.
At 6 weeks, the embryo weighs about 5 grams and is about 20 mm long. It grows a millimeter per day. Almost all of his organs are formed. There are even convolutions in the brain. And facial features become more and more distinct.
At 7 weeks, doctors stop calling the little man an embryo. Now he is a fruit. And it will remain so until the birth. The baby is very mobile in the uterus, moving with all his might, surrounded by amniotic fluid, but the mother does not yet feel his movements. The fruit is still very small.
At 8 weeks, the baby's size can be compared to a prune. It’s still a baby, but the body is already formed. There are even tiny nails on my hands. In the future, all organs and systems will only improve.
Nine weeks is the minimum period at which a doctor can see the so-called genital tubercle in the fetus and guess its gender. The accuracy of this “prediction” depends on the experience of the doctor and the quality of the equipment used.
Next week marks the first screening - ultrasound plus blood test. The baby has grown so much that the doctor can accurately diagnose possible chromosomal abnormalities in him.
Week 11 is the last week in which the screening will be informative. Don't forget to pass! The baby is growing rapidly. Blood began to form on him, and colorless vellus hairs appeared on his head.
With a two-dimensional ultrasound at twelve weeks, the baby now looks more like a small humanoid, but with a three-dimensional ultrasound, facial features are visible. True, there is not enough fatty tissue yet, and the baby’s face looks very thin. The first innate reflexes and facial expressions appear.
All 9 months of pregnancy in 4 minutes.
Next week, some mothers begin to feel the first movements of their babies. These are mainly women who are not carrying their first baby. The height of the children reaches 10 centimeters and their weight is 50 grams.
At 14 weeks, the gender of the baby is clearly visible on an ultrasound. There shouldn't be any mistakes. However, sometimes it cannot be determined if the baby is in uncomfortable position. Babies at this gestational age begin to make breathing movements and squint if a bright light source is pointed at their mother’s belly.
By the fifteenth week, mommy’s pregnant belly begins to appear. You have to buy clothes for expectant mothers or those that fit your rounded belly.
By this time, the placenta is fully formed, protects the fetus from infections and serves as a transmitter of nutrition and oxygen from the mother’s body.
16 weeks is a special period in the development of a child, since the thymus gland is formed - this is a temporary organ that gradually, over the course of 30 years of life, disappears in all people. In addition, the brain is actively developing, and the bones begin to accumulate calcium.
At seventeen weeks, some mothers will notice that their shoes are too small or narrow for them. This occurs due to swelling of the legs. Temporary phenomenon.
The fetus develops the rudiments of molar teeth. He already has tactile sensations, touch. That's why he loves to feel his body.
18 weeks is the ideal time for a second ultrasound screening. The baby is already big and most of the markers of chromosomal abnormalities are visible. Almost all women already feel fetal movements and it is at this stage, on an ultrasound, that they find out who they are expecting - a boy or a girl. Approximate height the fetus is 20 cm, and its weight is close to 400 grams.
The baby is becoming more and more like an ordinary newborn, albeit very small and thin. At nineteen weeks, he already swallows amniotic fluid and pees in it. Spinning in the uterus with might and main. Can change the head position to a transverse or pelvic position daily. At this stage, doctors do not pay attention to the presentation of the fetus.
Twenty weeks of gestation are marked by an improvement in the child's hearing. He quite clearly, as far as possible, hears the beating of his mother’s heart and her voice. You can understand how a child hears if you completely lower your head into the water and ask someone to say something. This is how he hears through the amniotic fluid. Also, this is the period when the fetus reaches a weight of 500 grams, and if it is born now, doctors will be obliged to fight for its life.
By the 21st week of pregnancy, the fetal heartbeat can be easily heard using a special wooden tube - an obstetric stethoscope. The baby continues to grow. Fat is deposited around his organs. This is necessary for their normal functioning after birth.
At 22 weeks, the weight of the fetus is about 700 grams and its height is 22 cm. The intrauterine daily routine is formed. Usually the baby at this stage sleeps during the day, involuntarily rocked to sleep by his mother, and is awake at night.
By twenty-three weeks, the baby's hearing is so improved that he can distinguish between familiar and unfamiliar voices. The vocal cords are formed and subcutaneous fat is deposited. If you now do a three-dimensional ultrasound, you can clearly see the child’s face and understand which parent he looks more like.
At 24 weeks, the baby can distinguish between light and dark and reacts to flashes of light. But the eyes are still devoid of pigment. It will appear in about a month. But the final color of the eyes will be formed only 4-6 months after birth.
At 25 weeks, the weight of the fetus approaches one kilogram, and its height is about 40 cm. In the future, the baby will not grow as actively in length; at birth, full-term babies have an average height of 50-55 cm, but will gain at least another 1.5-5 cm in weight. 2 kg.
At the 26th week of pregnancy, the fetal hair acquires an individual shade; it is no longer snow-white. The lungs are actively developing, but if the baby is born now without medical preparation (dexamethasone injections to the mother), then he will only be able to breathe on a ventilator.
At twenty-seven weeks, the fetus occupies the entire uterine cavity, so it is less likely to turn upside down and back again. However, it is too early to worry about his presentation. By the way, a doctor can easily determine the position of the fetus at this stage by palpating the pregnant woman’s abdomen on the couch.
If you do an ultrasound at the twenty-eighth gestational week, then mommy will be able to see her baby sucking his thumb! This habit will remain with him even after birth. The sucking reflex is very important for the first months of a child's life. And the fetus has learned to cry, and sometimes real tears flow from its eyes!
At 29 weeks, the weight of the fetus is approximately 1.5 kg and the height is about 45 cm. No special development of organs occurs. Essentially only the lungs develop. They produce surfactant - a substance that will prevent them from sticking together after birth.
Thirty weeks is the ideal period for undergoing a mandatory third ultrasound. The doctor looks at how and exactly how much the child is developed, whether the utero-fetal blood flow is in order, whether amniotic fluid. It also gives the approximate weight of the fetus. Depending on these data, we can assume whether there is a tendency to give birth to a large child.
At 31 weeks, the fetus is so developed that it can see and hear well. True, in utero its eyes are almost always closed, since keeping them open in water is not very comfortable. In boys, the testicles have descended into the scrotum. And the appearance of the girls’ genitals became common - the labia majora covered the labia minora.
On next week the fetus undergoes a leap in the development of the immune system. She actively produces antibodies. The adrenal glands, which produce steroid hormones, also function.
At 33 weeks the baby weighs about 2400 grams, almost like a full-term baby. And, most likely, she will be able to breathe on her own if she is born at this time. Nevertheless, he is still immature, and mommy should try to “hold out” for at least another 3 weeks.
The next week is the beginning of the last month of pregnancy, the eighth. The weight of the fetus is approximately 2700 grams, and some babies have already gained 3 kilograms. The bones on the baby's head are movable to make it easier for him to be born. Almost all the children lay down with their heads down. But even if the baby at this stage is in breech, there is still hope for its revolution, if there is not too little amniotic fluid.
35 weeks - at this period some babies are born. But even though they are officially eight months old, born ahead of schedule, in almost one hundred percent of cases do not require rehabilitation and are not in children's department or intensive care after birth, and in the ward with the mothers.
39 weeks. More often these are those who ovulated a little later than the standard 12-14 days of the cycle. At the same time, children are born completely normal weight. If the ultrasound shows that the fetus feels well, is actively moving, and the woman’s cervix is not “oaky,” she is admitted to the hospital and waits for labor to begin on its own.
40 weeks of pregnancy from conception or 42 obstetric, the last one that doctors can give while waiting for the onset of labor. But more often this week they are stimulated.
In order for the program to create your personal pregnancy calendar, enter the date of the first day of your last menstruation. All obstetricians and gynecologists accurately calculate the gestational age in this way.
This way you can figure out what to expect in a given week of pregnancy. It is very interesting. Try it!
