9th week of pregnancy

9th week of pregnancy


The 9th week of pregnancy marks the beginning of the third month of pregnancy. The baby continues to develop actively. The size of your baby is now 27-35 mm and its weight is about 5-6 g. The brain is already divided into two hemispheres and the first convolutions are being formed. We distinguish the cerebellum, which will be responsible for the smooth and coordinated movements of the child.

What happens to the baby at 9th week of pregnancy?

At the 9th week of pregnancy, the fetus reaches a height of just over 2 cm and the weight fluctuates within a few grams. The process of formation and development is in full swing:

  • The cardiovascular and nervous systems have already been formed, limbs are being defined and muscles and bones are growing.
  • The cartilaginous skeleton is compacted, the spine grows and the coccyx is formed instead of the tail.
  • The future face is modified: labial folds are formed, the mouth lengthens, the eyes approach and increase, become covered with a film and cartilaginous ears and lobes are formed.
  • Against the background of the development of facial structures, the lips move and even swallow.
  • The size of the chest and abdominal cavities grows for increasing internal organs.
  • Inside the body, the intestines continue to grow and develop. The liver and gallbladder and spleen is formed, the anus is formed.
  • In the chest, the heart increases and no longer sticks out, the bronchial tree branches, the atrial septum is laid in the already working heart and the mammary glands are laid.
  • In the central nervous system, the cerebellum grows, which is responsible for the future coordination of movements, the pituitary gland is formed, which affects growth and development. nerve nodes and spinal fibers are formed.
  • The thyroid gland begins to work in the endocrine system, layers of the adrenal glands grow, producing their own hormones.
  • The hematopoietic system of the fetus begins to produce the first lymphocytes that protect the baby. Lymph nodes are formed.
  • The genitals are differentiated and there are distinguishable signs of the sex of the baby.
  • Against the background of the growth of muscle tissue, the movements of the limbs are already possible.
  • The umbilical cord develops and thickens, through which the child is inextricably linked with the mother and both receives nutrients and is released from waste products.

A fetus surrounded by the amniotic fluid is clearly visible on ultrasound in the uterine cavity. You can calculate the heart rate which should be around 120-140 beats per minute. Ultrasound data allows you to assess the development and size of the fetus and clarify the pregnancy age and the state of the placenta.

The coccygeal-parietal size (KTR) of the fetus is measured from the coccyx to the crown of the head to determine its size. Usually, at the 9th obstetric week, the fetus’ CTE is around 27 to 35 millimeters.
