This week marks a developmental milestone for your baby
All of your baby’s internal organs are formed and more or less ready to carry out their functions [1]. Your baby can see, hear, and can swallow, and suck.
The baby’s nervous system continues to produce neurons and improve interneuron connections. Their cerebral cortex forms grooves and convolutions, and the differentiation of the cortex’s functional divisions continues. The endocrine system — which produces hormones for everything from metabolism and sleep to growth regulation and sexual function — works at full capacity, playing its role in the functioning of all of your baby’s organs and systems.
At this time, not all mothers can feel their baby’s movements [1]. But if you already notice them, they will soon become more pronounced.
If you are expecting twins
The babies are starting to get a little cramped, so you can probably feel their every movement very clearly, while mothers carrying single pregnancies haven’t felt anything at all.
What can be seen on ultrasound
The image shows a baby during your current week of pregnancy. The baby is lying on their left side, facing the screen.
A clearly defined contour of the head allows you to examine in detail the frontal bones, paired nasal bones, and chin. The upper and lower jaws are separated by a narrow strip — which is the mouth.

In the next picture, the heart is clearly divided into the atria and ventricles. Above the spine, in the lower part of the image, the aorta is barely noticeable.
The stomach is visible, it looks like a dark oval in the image. Deep in the amniotic fluid, you can see the baby’s hand.

The next image shows twins. One of them sits in the foreground while the other lies slightly higher.
You can see the tiny feet and toes of the baby in the foreground. The limbs of the other baby are partially visible.
