Fetal development in the seventh month


The seventh month of pregnancy includes the twenty-eighth to thirty-first week of pregnancy. The growth and development of the fetus in the seventh month can be described in detail as follows:


week 28


The 28th week marks the beginning of the last trimester of pregnancy; At that time the weight of the fetus is the weight of the eggplant; That is, just over a kilogram, when at least 37.6 cm in length, the fetus appears to be full this week; All major body systems are present and function when more is needed. Over the next few weeks of development, the fetus can show reflexes and exercise certain skills; Like sucking, moving the limbs, breathing, hiccups called hiccups, coughing, etc., the fetus goes through a development that affects all its organs, which can be explained in detail below:

  • The lungs are growing stronger and more able to support the life of the fetus outside the womb.
  • The appearance of the skin of the fetus improves, wrinkles disappear as more fat accumulates under the skin, making the skin appear smooth, and the white fatty substance and fine hair covering protect the skin of the fetus in the womb, thus improving the appearance of the skin.
  • The grooves and folds of the brain grow more prominent, and the spinal cord and the nerves that branch off from it continue to wrap in a white, greasy substance called myelin, a process that continues during pregnancy and the first year. 
  • The life of the child begins to wrap layers of nerves responsible for the movement of the child, the first is the protective substance melanin, then the nerves that support the movement of the child, and then the sensory nerves. 
  • In this case, it should be noted that the substance helps to speed up the transmission of information between the child's brain and the nerves in the body.
  • Compared to pre-pregnancy, the fetus's heart rate slows down to about 140 beats per minute; This number is equivalent to twice the mother's heart rate.
  • development of the endocrine system, its important enzymes, and processes; The adrenal glands secrete androgens and estrogens, which stimulate the mother's hormones to produce milk.
  • The fetus is physically active because it spends more time in REM sleep and the dreams associated with it, and the duration of the fetal nap ranges from 20 to 30 minutes.
  • Thick, invisible hair grows on the baby's head, or he may be born bald.
  • The growth of the fetal muscles and the increase in mutual alignment makes the fetus's vision clearer.
  • The growth of the placenta and the increase in blood flow within it mimics the accelerated growth of the fetus in the last three months of pregnancy.
  • Eye development. Thin eyelashes grow around the fetus's eye. Tears may be produced at this stage. The muscle fibers that make up the iris of the eye develop, giving the eye its final color. In the figure, it should be noted that the final color of the eyes of the child will not be known until after a few weeks, at least after birth.
  • the fetus is in a position and position suitable for birth; heads down toward the pelvis, at which point the fetus can assume the breech position; This can be known from the regular review by the doctor that over time the fetus can turn around and take the position. The head is ready for natural childbirth, and if it does not turn, the doctor decides that a cesarean section is required because natural childbirth is not possible.


week 29


At the 29th week of pregnancy, the fetus is about the size of a pumpkin or a chicken, weighing about 1.2 kg and measuring about 38.6 cm in length. In the remaining weeks, the fetus gained about half its weight and rapidly grew into muscles, lungs, and head in a process that mimics brain development. 

Open your eyes and focus. It continues under the skin for smoother skin, and the preparation of the fetus continues until the day of birth, during eleven weeks with the increase in the weight of the fetus and its development affecting all its organs, 

it will look like a young and mature child without a white fatty layer, soft warm hair covering its skin, and enjoy good health. 

This is necessary for the mother to get the rest she needs and vital nutrients such as protein, and vitamin C, there is also folic acid, iron, and calcium, all of which can be obtained from food sources that can be identified and identified in cooperation with the doctor.

week 30


Starting in the 30th week of pregnancy, the fetus weighs about 1.3 kilograms this week, and at this stage of pregnancy, the fat remains confined under the skin, which makes the fetus appear fatter and less wrinkled, nails begin to appear and its reflexes develop more, the fetus becomes aware of contractions Braxton Hicks During this week, the fetus undergoes the following changes:


  • The growth of the baby's brain and its transformation from a smooth surface to a normal brain shape full of grooves and folds aims to increase the amount of brain tissue so that the fetus is ready to develop its intelligence outside the womb.
  • lanugo disappears; In the last three months of pregnancy, it is the soft and warm hair that regulates the body temperature of the fetus as the baby’s brain and new fat cells take over this task and are responsible for regulating the body temperature of the fetus, however, some fluff can be seen on the back and shoulders of the baby was born.
  • The bone marrow is distributed to multiple tissues and then to the spleen, where it takes over the production and production of red blood cells, which helps the fetus grow better at birth.

week 31


By week 31, the fetus weighs about 1.5 kilograms and is about 41 centimeters long, gaining about a quarter of a kilogram each week before birth. Assuming a certain position is maintained until birth, the fetus's genitals undergo some changes, including repositioning; If the fetus is male, the testicles move and descend into the scrotum, and if it is female, the clitoris is relatively formed, and another develops. It includes the following points:


  • The ability to open the eyes and respond to light.
  • The brain develops rapidly; This enables the child's brain to receive information and send signals.
  • In response to loud nearby sounds, the fetus falls into a coma upon hearing these sounds.
  • The kidneys begin to produce urine.
  • The fetus is developing the ability to breastfeed, swallow and burp the fetus.
  • The continuous development of the child's sense of sight, hearing, taste, and touch, in addition to the sense of smell that develops after birth.


An overview of fetal development


The fetus develops and grows in the womb during pregnancy; From fertilization to birth, this process of growth and development is called prenatal growth. 

Nine months to three main stages, each stage consisting of approximately three months, called a trimester, 

each stage accompanied by a series of changes and developments. Depends on the month of its occurrence The weeks of pregnancy and childbirth vary according to the number of days in the month, 

so the duration of pregnancy may be nine or ten months, and this is normal, and information about the gestational age and the date of delivery can be obtained by visiting specialists who, in turn, will clarify the understanding of the growth of the pregnant fetus, 

This indicates the development of the fetus and the changes that the fetus and mother are going through at this stage of their lives.
