How to transfer weeks of gestation in months?
To begin with, it must be said that with such calculations, doctors use the term obstetric term. The main difference in its establishment is that the starting point of the gestational period is the first day of the last observed menstruation. In addition, doctors always consider the months for 4 weeks, while in the calendar can reach up to 4.5.
Given these facts, a woman in the position can independently calculate how many months this is 24-25 weeks of pregnancy. Thus, dividing the given number of weeks by 4, it turns out that this is 6 exactly, or 6 midwifery months and 1 week.
What happens to the future baby at this time?
At the 24th week the fetus looks very much like the little man whom his mother will see after birth. The body length to this point is about 30 cm, and the weight is about 600 g.
By this time period, all organs and systems are practically formed. Further development takes place in the direction of improvement.
Thus, the fetal respiratory system ends. A bronchial tree has already been formed. The lungs begin to gradually become covered with a substance such as a surfactant - it is he who plays an important role for the first inhalation, preventing the lungs from collapsing (clumping).
Sweat together with sebaceous glands are actively working. There is further development and improvement of the brain. It starts to increase the number of convolutions and the depth of the grooves. At the same time, the sensory organs of individual reflexes are perfected. The movement of the fetus becomes more coordinated, which is clearly visible when performing ultrasound. The kid can easily catch his foot with his pen.
Light-sensitive pigments are already present in the visual apparatus. This is easily confirmed by a practical test: when a beam of light is directed to the front abdominal wall of the mother, the child begins to squint.
The taste receptors also work. Scientists have proved that at this time the child is able to distinguish the taste of amniotic fluid, which they involuntarily swallow.
In most cases, at this time, the future baby has already formed the regime of the day. The pregnant woman herself can note that after a long calm, when there are no movements, the waking phase begins. The kid starts to actively move, turns over.
What happens at this time with a future mother?
The stomach is already bulging forward. The bottom of the uterus at this time reaches the level of the navel.
A significant increase in weight is reflected in the state of health of the pregnant woman. She begins to tire quickly. Legs by the evening always hurt, after even a short walk. This is caused not only by the load on them, but also by the difficulty of circulation in the lower part of the trunk. In turn, this fact is due to the fact that the fetus strongly presses the veins of the small pelvis, as a result of which the blood flow is disturbed.
However, often, at this time, the woman begins to observe the first phenomena of difficulty breathing. After climbing the stairs, dyspnea often occurs. This is due to the fact that the uterus puts pressure on the diaphragm. In this case, the space for the lungs becomes less, as the fetus grows.
Thus, the pregnant woman must constantly monitor her health and, if worsened, consult a doctor.
