Fruit (development, size)
The first trimester of pregnancy is ending, and by this time the children’s organism has achieved great success in its development. It affects a small heart: every day it pumps 23 liters of blood! By this time, all baby teeth of the baby are fully laid.
But this accomplishment does not end there: during the 13th week of pregnancy, bone and muscle tissue continue to take shape, the digestive system of the child develops. Thus, the first villi are formed in the intestine, which in the future will take part in the digestion and promotion of food. The pancreas is already producing its first insulin. The vocal apparatus of the child began to form. The genitals are increasingly differentiated: this week, the genital tubercle is lengthened and either gradually turns into a penis, or is bent downwards, forming the clitoris. Germ cells or the prostate gland develop, depending on the sex of the fetus.
The appearance of the child also gradually acquires more expressive features. Gaining momentum in the growth of the body – over time, it will look more and more relative to the head. Now the coccyx-parietal size of the fetus is on average 7-8 cm, and its weight ranges from 15-25 g.
A lot of work has been done on laying the main organs and systems, and now the turn of the emotional sphere has come. At the 13th week of pregnancy, the child is always active: he listens, learns new skills, reacts to signs coming from the outside world (sounds and silence, light and darkness, heat and cold, various kinds of touches). Now the baby is more awake, falling asleep only for a few minutes and waking up again. Fetal movements are no longer as chaotic as before, and have some orderliness.
At 13 weeks of pregnancy, the baby distinguishes between smells and tastes of food absorbed by her mother. He may not like everything from the proposed menu, and on the contrary he will love some products. Just imagine: he not only knows how to suck and swallow, he already yawns, smiles and makes grimaces! Crumb is very comfortable in my mother’s tummy: here it is warm, cozy, calm, soft, the sounds coming from the outside pleasantly lull you, it is surrounded by a soothing gloom …
If by this time you have not yet established the tradition of communicating with the child, the transition to the second trimester is the very same time. The most peaceful period for mother and baby begins – use his every minute to his and his pleasure.
At 13 weeks of gestation, a woman is usually not sick. “Hormonal rebellion” is over, the body has adapted to the changes and got used to the new state. The second trimester is the most tranquil of all periods of pregnancy: most of the signs, symptoms, and ailments associated with the onset of pregnancy are over, but still you can’t call it absolutely careless. It is time to come to grips with the prevention of stretch marks, constipation and edema.
By the 13th week of pregnancy, the waist gradually disappears and the tummy is rounded. Most likely, you have already switched to clothes for pregnant women. Otherwise, update your wardrobe now. Pay special attention to the bra: it should be the size of the growing breast and it should be well supported (with wide straps). The breast will grow and fill throughout the entire period: compared to the pregenerative state, its weight will increase by at least two or even four times by the end of pregnancy.
Uterus in the 13th week of pregnancy
As well as the fetus, the uterus continuously grows, rising higher and higher. At 13 weeks of pregnancy, it fills almost the entire hip area and rises higher – in the abdominal. Neighboring organs will have to make room, and with this there will be some inconveniences in the future: heartburn, shortness of breath and others.
During each examination, the gynecologist will now measure the height of the uterus floor. It is equal to the number of weeks in centimeters. So, at 13 weeks of pregnancy, the uterus has a height of 13 cm, width – 10 cm. It can already be easily felt, especially if it is not obstructed by a thick fat layer.
In the second trimester, the uterus tone will no longer be so terrible – it becomes softer and more elastic, and, as a rule, decreases for a while.
In moments of increased uterine tone, you can feel the sinking and pain in the lower abdomen. At such moments, you just need to lie down and rest. If this happens often, the doctor will advise you to put candles with papaverine or drink Ginipral, for example. But many mothers do without any medication. Just learn once again not to “worry” your uterus: do not walk in heels, do not carry weights, do not be nervous over trifles.
The stomach can also hurt due to the formation of gas. Track your diet and the presence of such a relationship. Some foods may have to be excluded from the diet.
For most women, the stomach at the 13th week of gestation already shows their position: it has become round, or even markedly increased. But it happens that the tummy is now only scheduled, and it seems as if you were just a little better.
If abdominal pain at the 13th week of pregnancy is accompanied by a bloody bleeding, it is better to warn your doctor about it. Try to limit the time of physical activity, and in the case of the start of bleeding immediately go to the hospital.
It is not uncommon pain on the sides of the abdomen at week 13. It stretches the muscles that hold the uterus, and the uterus itself stretches all the time. Such pains are not dangerous, but if you are agitated, then lie down to rest – it does not hurt.
Pain in the legs, accompanied by cramps in the calf muscles, is a signal of lack of calcium in the body. Usually, such pains occur at night. Increase the amount of calcium-containing foods in your diet – this element is now very important. Only give preference to plant-based sources of calcium, since the spring of the animal quickly stiffens the spring, which is undesirable when the child passes through the birth canal.
