9th week of fetal development

Firstly, your future baby has grown up, reached the mark of 2-3 cm and weighed as much as 4 g, and most importantly, this is just the beginning. Secondly, his brain continues to actively develop, it is divided into two hemispheres, which are densely covered with the first gyrus. The cerebellum is formed, which coordinates the child’s movements, in particular controls them during swimming. And the refinement of the nervous system helps the first reflexes of the baby, such as swallowing and sucking.

Every day the baby becomes more and more like a normal baby:

  • he has put on weight;
  • his muscles continue to grow;
  • he’s already straightening his back;
  • he doesn’t yet hold his head tightly to his chest, but has a clearly defined neck;
  • his tummy is rounding and his tail is gone.

The baby’s limbs continue to develop, becoming longer and thicker. The toes are no longer webbed, but they are still present between the toes. The palms of the hands are becoming familiar. If you look at the face, you can see that the lips are already formed. Milk teeth are beginning to emerge in the mouth.

Internal organs and other systems of the child’s body also continue to develop. The immune system improves, lymph nodes are formed. The baby’s body also begins to produce adrenaline.

The ninth week is the period of movement. The baby can move his legs and arms, but all movements are not yet visible to the mother.

During this week, the egg supply runs out and the baby subsequently receives everything it needs with the help of the placenta. From this point on, its nutrition becomes strictly placental. Therefore, the mother needs to monitor her diet very carefully, because everything she eats or drinks goes into the baby’s body.

If you do an ultrasound in the ninth week of pregnancy, it will show that the fetus is well visualized in the uterine cavity and surrounded by amniotic fluid. This examination allows you to record how the baby moves, set the heart rate, which should correspond to 120-140 beats per minute.

Also ultrasound examination helps to give a proper assessment of fetal development, to confirm the timing of pregnancy. And information about this can be obtained with the help of measurements of the crumb from the coccyx to the parietal. Such measurements are called coccyx-parietal or KTR of the fetus, and at this term it corresponds to 20-22 mm, but 15-30 mm is also normal.

What's going on with mom?

If we talk about external signs, they are still not so noticeable to others. Only the mother herself can notice that she has gained a little weight, her breasts have changed in size and, unfortunately, stretch marks may appear.

Another not too pleasant news is that toxicosis remains still with you. In this case, not only will you not get better, but you can easily lose a couple more pounds. Anyway, if you liked tight things before, it’s time to say goodbye to them and start updating your closet.

An interesting phenomenon of this term of pregnancy is that your hair and skin can do wonders. Your skin can become perfectly smooth and your hair can become shiny. Although these phenomena are rather uncharacteristic for most women, more often facial skin and hair suffer, but their appearance will be restored afterwards.

A pregnant woman may become very sensitive to smells, and even pleasant and previously favorite smells may cause nausea.

At this stage, women may still feel irritable, tearful, excessive emotions, and have a changeable mood. All this is completely normal for a pregnant woman. The main thing is to remember that all this is temporary and will end either with the flow or with the end of pregnancy. It is important that relatives and especially the spouse treat the changes with understanding.

You are too young to feel the fetus moving. But slightly uncomfortable sensations in the lower abdomen or lower back may make themselves known. If the pains are moderate and situational, you should not worry, but if they become more intense and frequent, you should see a doctor and do an ultrasound.

In addition to physical changes, there are psychological changes waiting for you. Thus, a pregnant woman is overcome by doubts whether she will be a good mom. To say goodbye to all doubts, expand your ideas about motherhood – by reading special literature and watching educational videos. And if the future father keeps you company, it will be doubly pleasant and useful.
