The development of the fetus during pregnancy 13 weeks passed the most dangerous stage, and the woman underwent a difficult trimester of his gestation. The severity of the manifestations of early toxicosis is gradually lowering and one can fully enjoy one's condition. The greatest joy of a future mother will be brought by the first ultrasound in pregnancy of the fetus at 13 weeks, when she can get a photo of her baby or admire his three-dimensional image on the monitor screen.
Fetus in the 13th week of pregnancy
The baby already has fully formed rudiments of almost all teeth, tiny hairs and a unique pattern on the finger pads. The head is no longer so huge and becomes more proportional to the body, which is somewhat stretched and grown up. The size of the fetus in the 13th week of pregnancy varies in the range of 65-80 mm and its dimensions resemble a plum or peach. He is steadily growing and developing, which can not but please the future mother and her loved ones.
Anatomy of the fetus 13 weeks
On the face you can already recognize the outlines of the nose and chin. Already there is a process of laying the tissues necessary for the subsequent formation of the bone apparatus of the baby, and in the ultrasound examination a pair of ribs are already seen. There is also an intestine, which took its place in the abdominal cavity. The pancreas of the embryo at 13 weeks is able to produce insulin and fully fulfill its functional purpose. This week is a turning point, because it is characterized by manifestations of individual features of the body structure in the female and male embryo. For example, fetal development at week 13, if it is a boy, suggests the appearance of the prostate. The girls also have fully formed ovaries, which already have eggs.
The period of pregnancy is characterized by a huge number of all kinds of research and analysis, the results of which must comply with generally accepted medical norms.
So, for example, the KTR rate at 13 weeks is 63 millimeters. But this indicator requires the determination of the exact period of gestation, since the error of several days is fraught with a significant increase in CTE, which can be taken for pathology.
The weight of the fetus at 13 weeks is only 130-140 grams, which does not prevent the baby from freely swimming in the amniotic fluid, which he can already "walk on a small one." Coordination of movements is gradually returning to normal, which allows you to feel the movement of the fetus at 13 weeks. However, these sensations can catch very sensitive mummies, which bear the second child.
The BDP of the fetus at 13 weeks is approximately 24 mm. and makes it possible to assess the state of the nervous system of the embryo. Again, the reliability of the data depends entirely on the clearly established period of gestation. Do not be frightened if the size of the fetus at 13 weeks somewhat does not match the approved table, because everything is individual.
Palpitation of the fetus at 13 weeks
The measurement of this indicator makes it possible to establish the degree of viability
At the 13th week of pregnancy, the size of the abdomen starts to increase gradually and extend beyond the small pelvis. The woman begins to feel shy in the usual clothes, and it is worth taking care of a suitable wardrobe. It is quite advisable to find out the location of the fetus at week 13 in order to exclude the tone of the uterine walls and the wrong placenta previa.
