The fetal size at 9 weeks continues to increase, about 1 mm daily. The human embryo on the 9th week of pregnancy begins to raise its head, as its neck has already grown a little. His arms are now longer than the legs, they develop faster. And soon the baby will learn to squeeze the fists.
The CT of the fetus (the size of the embryo from the coccyx to the crown) at 9 weeks is approximately 2-6 cm. Its weight is from 2 to 7 grams. Now it can be compared in size with a cashew nut. The embryo continues to straighten, its limbs can bend and unbend, there are rudiments of nails.
At the time of 9 weeks of pregnancy, the size of the fetus is as follows:
- internal diameter - 33 mm;
- the area of the body is 972 mm;
- volume - 16 380 mm cube;
- biparietal size - 8.5 mm;
- volume of yolk sac - 5 mm cube.
Fetal development at 9 weeks old
The fruit in 8-9 weeks passes the next stage of development of the most important systems and organs. He has a cerebellum needed to control coordination, the pituitary gland, which produces the first hormones, the middle layer of the adrenals, which produces adrenaline, lymph nodes. In addition, the mammary glands are laid and the sexual organs begin to form.
At 9 weeks, the embryo gradually builds up with muscles, its bones strengthen, the heart and nervous system work and their work is increasingly being improved. The heartbeat (heart rate) of the fetus at 9 weeks is 170-190 beats per minute.
So far, the fetal head makes up most of the size of the fetus. However, the face is more refined - the eyes are slightly close, closed for centuries, which will not open soon. The baby's mouth becomes expressive, corners and folds appear. The kid can swallow and frown. At 9 weeks the neck of the fetus already varies.
And one more important achievement at this age is the ability to urinate. But not through the urogenital system, but through the umbilical cord. Now the burden on the kidneys of women increases, and run to the toilet will have more.
The umbilical cord, by the way, becomes longer and stronger, the placenta begins to function, although so far most of the functions are performed by the yellow body.
Sensations of a woman on the 9th week
Pregnant on this term is subject to sharp changes of mood, she quickly gets tired and all the time feels drowsy. Toxicosis in full swing - especially strong its manifestations in the morning hours. All this is the work of hormones that have not yet returned to normal after such a change as the onset of pregnancy.
As for the abdomen, for 9 weeks of pregnancy its size does not change in any way. The fruit is still too small and fits perfectly in the flat mother's tummy. And yet a dream on the stomach can cause some discomfort, sometimes even leading to awakening.
Breast at this time becomes particularly sensitive and increases in size. Some women observe the appearance of transparent discharge from the nipples - it's colostrum. So your chest is getting ready for lactation.
At a period of 9-12 weeks, doctors give the pregnant woman a direction for analysis to exclude TORCH infections. Of course, it is better to undergo this examination at the stage of pregnancy planning, but if you did not, go through it now. Primary infection during pregnancy with these infections is extremely
Not for nothing during the woman's registration in the women's consultation, she is asked about the presence of pets. Cats and cats are carriers of toxoplasmosis - one of the causative agents of TORCH infections. And if you have a cat, ask a member of the family to clean up excrement for her - that's where the pathogens are.
Whatever it was, adjust yourself to enjoying your position. Just imagine that a new life is developing in you. And this tiny little man completely depends on you and very much feels your mood.
