Fetal Movement in the Seventh Month
During the seventh month of pregnancy, the fetus undergoes significant developmental changes. At this stage, fetal movements become more pronounced and frequent compared to previous months, particularly in male fetuses, as their sensory systems become fully developed. It is important to note that medical professionals track fetal growth in a weekly format rather than monthly, as each week presents distinct milestones in the fetus’s development.
Causes of Reduced Fetal Movement in the Seventh Month
A common concern for pregnant women during the seventh month is the reduction of fetal movement, which can stem from various factors. Some of these factors may indicate serious issues:
- Poor nutrition.
- An inadequate supply of oxygen reaching the fetus via the umbilical cord.
- High blood pressure in the mother.
- Genetic influences on the fetus.
- Umbilical cord complications.
- Excess body fat in the mother, leading to obesity.

Week 27
- The fetus weighs approximately 850 grams and measures about 36.5 centimeters in length.
- The sleep-wake cycle begins to stabilize, often differing from the mother’s sleep patterns.
- The eyelids begin to open.
- The brain cells and tissues are still developing.
- Although the lungs are not fully matured, they can function with the aid of a ventilator if birth occurs prematurely.
- The fetus possesses significantly more taste buds than an adult, allowing it to recognize its mother’s milk.
- If male, the testes descend into the scrotum; if female, the ovaries start to fill with follicles.
Week 28
- The fetus’s weight reaches 1 kilogram, and its length measures 37.5 centimeters.
- Eyelashes have developed, but the fetus cannot yet move its eyelids.
- The brain continues to grow.
- The immune system begins to form as antibodies transfer from the mother through the bloodstream.
- The lungs and liver approach their final stages of development.
- The fetus gradually turns its head downward in preparation for birth.
Week 29
- The fetus weighs around 1,150 grams and measures 38.5 centimeters in length.
- The head size increases, allowing better control over breathing and body temperature.
- It secretes the hormone estriol, which stimulates milk production from the adrenal glands.
- Fetal movements increase due to its higher energy levels.
- The fine hair covering its body starts to disappear.
Week 30
- The fetus weighs approximately 1,400 grams and measures 40 centimeters in length.
- Fat cells begin to accumulate beneath the skin.
- The sleep cycle is now fully established.
- All senses start to function, though eyesight is limited to viewing objects that are near.
