Embarazo mes a mes [Fecundación y desarrollo de embrión a feto, y a bebé]

We know that every mother would like to see how her baby grows in her tummy, so today we are not going to talk about care, studies or recommendations for pregnancy, we have made a video that will allow you to see everything that happens in your baby's little world in the safety of your tummy so enjoy and remember that knowledge is power It is important to make it clear that the weeks of pregnancy do not begin to be counted from the fertilization because unless in vitro fertilization is performed it is practically impossible to know the exact moment of fertilization. In obstetrics we start counting from the first day of your last period, so in this video every time we say "weeks " of pregnancy we mean from the first day of your last period. We know that ovulation will occur around 14 days after your first day of menstruation, but after the egg is released from the ovary it will still take a couple more days to reach the fallopian tubes and meet the sperm.

Once the sperm penetrates the egg, they combine into a single cell called a zygote, as soon as the zygote begins to divide it will become an embryo. The embryo will continue to divide and travel through the fallopian tubes until it reaches the uterus. Many moms have asked us "When am I going to start feeling pregnancy symptoms since I had intercourse yesterday?

" Remember that until now the embryo has not implanted in the uterus so it is impossible for a woman to detect any pregnancy symptoms, but in the middle of week 3 the embryo reaches the uterus, implants itself and begins to release hormones, mainly the hormone chorionic gonadotropin, this is the hormone that is released only during pregnancy and now if the mother can begin to feel the typical symptoms of pregnancy such as nausea, fatigue, mood changes, although each case is unique and there are women who They do not have these symptoms throughout the pregnancy. We are going to talk about the size of your baby during pregnancy and sometimes we do not perceive it so well in centimeters or millimeters, so we are going to compare it with fruits and seeds. At week 4 it is the size of a poppy seed.

The most obvious symptom arrives: the absence of the period, and the mother may begin to suspect something and although we do not detect it in the ultrasound, the embryo already has a heart. Right now it still looks very strange, elongated and without limbs, it has a yolk sac from which it will feed until the placenta begins to function. don't worry about missing the heartbeat or being told it's too small or not growing properly.

It is too early to detect it, even if you do not know the exact moment of fertilization, you can go to the clinic in very early stages and not even detect the sac of pregnancy, do not worry about this, you always have to give it a chance to go growing and follow up with ultrasound or hormonal monitoring. Its tissues begin to divide into three layers: the outermost or ectoderm will become the brain, the middle layer or mesoderm that will form most of the body, and the inner layer or endoderm that will soon be the respiratory and digestive systems. In week 6 it is the size of a rice.

We will observe and listen to the heartbeat, we at Creafam, having advanced equipment, can sometimes detect it between week 5 and 7. Folic acid is essential for the formation of the neurological system, so ideally the mother should not wait until this moment to start taking it, remember from three months before achieving pregnancy and during the entire first trimester you have to take folic acid. In week 7, a blueberry.

From the second month we no longer call it an embryo, at week 10 the fetal stage begins, it measures about 3 or 4 centimeters and we can already distinguish the outlines of arms and legs, rudimentary structures in the brain, although the neural tube is not yet present. closed and the abdominal wall may present a physiological hernia, don't be frightened, it is normal and it will close until week 12. In week 11 it is the size of a fig.

Around week 11 or 12 we can distinguish facial features such as the eyes, the formation of the ears, nose, mouth, jaw bones, already complete extremities of arms and legs and as we mentioned, the abdominal wall completely closed and we observe the bones of the skull also completely closed, the genitals appear, the liver eyelids and even nails. From week 12 the second trimester begins and now it really does look like a miniature baby. At week 15 it already looks like an apple.

Around the 15th week, that is to say, three and a half months, the babies already begin to swallow, they already begin to swallow their own amniotic fluid and they swallow it and urinate it. By the fourth month, the fetus is covered with fine hair called lanugo, which may be more visible on the eyebrows and upper lip. It may begin to make fine movements such as opening and closing its hands.

By week 20 it is the size of a coconut, we have reached the middle of the pregnancy from week 20 the fetus measures 18 to 20 centimeters and weighs around 300 grams. The brain, muscles and organs continue to develop so the changes will begin to be less in the physical aspect and a little more in their ability to feel and react to the environment. Now if the mother will begin to feel the first little kicks and with a device that can even be sold to us in pharmacies, which is a Doppler device, they can listen to her heartbeat.

In week 24 its size is compared to a corn. By the sixth month the baby begins to respond to sounds and that is why many mothers begin to play a little music or speak directly to the tummy, they can even react with sudden movements to a loud noise and we could even say that they get scared of sounds. loud noises but in reality it is just that they can already react to these stimuli.

At week 27 it is the size of a cauliflower. By the seventh month he already weighs a kilo and a half more or less and in addition to reacting to sounds, he is also beginning to react to light stimuli, although since he is already bigger and the space begins to fit him small, you will notice that the movements They are minor, but of course it is always important that your baby is moving. The fact that you perceive movements in the morning, noon, afternoon and night will be enough for you to know that your baby is fine.

Many years ago there was a scale to measure the amount of baby movements, supposedly the more the baby moved the healthier the baby would be, today we know that this is not true. The important thing is to perceive that your baby is moving during the course of the day and the alarm data would be if these movements abruptly decrease. On the contrary, when a baby is moving too much and even the blows that the baby generates hurt, do not worry, it does not mean that he is uncomfortable, it means that oxygen is reaching him well enough to have that vitality.

By week 33, which is already seven and a half months, it is the size of a pineapple. The baby assumes a head-down position fitting into the pelvis and at the same time pressing on the bladder, so the mother will surely have to go to the bathroom very often. Although she can't breathe yet, her diaphragm begins to move by imitating the respiratory movements that are necessary to breathe at birth, strengthening and preparing for that moment.

By the eighth month the baby is almost ready to be born and in case of premature labor it has a very good chance of being born without any problem. Most of the lanugo falls out, there is usually only a little left on the shoulders and the hair starts to get a little thicker, even in the ultrasound we can see if he is going to be born with a lot or little hair. At nine months the testicles of male babies should already have descended, if it is a baby the labia will already be fully formed.

By week 39, he is already a full-term baby, who doesn't have much growth left, since he already has the size and even the weight of a watermelon. The baby already has periods in which he stays awake and in which he sleeps and although we do not know for sure, he must surely dream something. There will be babies that by week 40 already look like the big pumpkins of November, at 40 weeks the baby already weighs about three kilos, some more, others less and it measures on average about fifty centimeters but its size can definitely vary, plus it is most likely that the baby will be ahead of or behind the calculated delivery date, don't worry about this, only in 5 % of pregnant women , the baby is born on the calculated date of delivery.

You just have to be a little careful, when a baby is already over the 40th week, the visits will have to be more continuous, because it is also very important for a baby to be postmature. But whether you decide to have a caesarean section or a humanized delivery, remember: At Creafam they have a team of specialists to accompany the mother and protect the baby on the day of birth. We wish you a very happy pregnancy and a dream come true.
