All future mothers want to know about the process of pregnancy and how the fetus develops in the womb. All information about how the baby from the tadpole turns into a baby with legs, hands, face is not only interesting, but also important for a future mother. Knowledge of how the fetus develops during pregnancy by week is important because all outgoing metamorphosis can carry information about how correctly this process is happening and how safe it is for a future child.
Sensations of the future mother
The main evidence of pregnancy is amenorrhea, in other words, the absence of menstruation and such physical phenomena as an increase in the abdomen, which is associated with an increase in the uterus. During the development of the fetus and pregnancy, a woman, according to average indices, is gaining from 11 to 13 kilograms. All the main symptoms of pregnancy are directly related to the level of changes in hormones in the blood and pressure, which during fetal growth is on the internal organs of a pregnant woman. The initial symptoms in the period of fetal development are sensations comparable to those experienced by a woman during the menstrual cycle (constant and unreasonable irritation, fatigue, bad mood). Hormonal restructuring, constant nausea, forces the body to make separate and definite changes to the habitual diet. Need to eat a little, but as often as possible, this will help prevent over-saturation of the stomach.
The main periods of pregnancy
The general development of the fetus is divided into certain stages, each of which has its own characteristics.
Phase one is called blastogenesis. It lasts 15 days from the time when fertilization occurred.
The next stage, called embryogenesis, lasts from 3 to 10 weeks. At the moment of this stage, the placenta develops intensively, and the rudiments of internal organs are formed. At the end of the second month, the embryo is almost completely human. The fetus has convex formations, which as a result develop into lower and upper limbs.
The stage of development of the embryonic period is observed in the period between the 11th and 26th weeks. Just during this period, the functioning of various organs of the embryo is noted. Also at this stage, the development of the muscular system as a whole is observed. There are dental rudiments. During this period, the child begins to react to external stimuli (to light, heat and sounds).
The so-called late embryonic period and development during pregnancy of the future baby is caused by a clear manifestation of external forms close to the final ones. From the 27th week until birth, the baby looks almost the same as before the birth. At this time, the mother takes a more rounded shape and rises, while stepping forward.
After 29 weeks, the development of the child is considered complete. At that moment, various organs and systems of the fetus are fully formed, and as a result of the formation of muscle and adipose tissue, its weight increases noticeably.
For the first time the baby opens his eyes near the 26th week. In the uterus, the fetus becomes a little cramped. At the 28th week of pregnancy, the fetus fills the entire space. Already starting from the 32nd week, the baby has fully formed lungs, they can function fully. Starting from the 35th week, the body takes a shape resembling roundness, and it also becomes plump. The maturation of all individual life systems continues on the ninth month. The location on the start of the head in the pelvis area baby gets on the 40th week. At the time of approaching the birth, the woman's stomach will increasingly pull down. During this period, it is very important to make special rotational lumbar motions as often as possible, which will ease the unpleasant sensations of the future mother.
In general figures, the pregnancy lasts 280 days (10 lunar months). The calculation of the development of the fetus during pregnancy and the beginning of the pregnancy itself is begun from the first day of the last menstruation. The most responsible months for both the mother and the future child are considered to be the first, second and late embryonic period.
