The early terms of the gestation process are always accompanied by numerous changes in the fetal and maternal organism. The future baby actively develops, receiving new organs and systems. The 8th week of pregnancy, on which a four-chambered heart is formed, is no exception.
Signs of pregnancy at week 8
In most cases, a woman by this time already knows about her interesting situation. Symptoms of pregnancy at week 8 are clear: the delay in menstrual periods is already 4 weeks, the pregnancy test shows two strips. There are also changes in the appearance of the pregnant woman. Future moms notice how their breasts are constantly increasing in volume, poured. The nipples turn dark and become sensitive.
Some women by this time are faced with manifestations of toxicosis. Nausea and vomiting that occur in the morning, after eating, again remind the woman of her situation. Vomiting 1-2 times a day is permissible, but with frequent attacks, worsening of overall health, it is necessary to consult a doctor. Frequent, indomitable vomiting causes not only weight loss, but also leads to dehydration of the body, which is dangerous for the baby.
8 weeks of pregnancy - this is how many months?
Having learned about pregnancy, many future mothers start to keep their own calendar, in which the term of gestation is counted. At the same time, for the starting point, they take the time that was indicated by the doctor (obstetrician). Physicians duration of pregnancy is always indicated in weeks, counting it from the first day observed before the conception of menstruation. In some cases, future mothers prefer to lead the duration of pregnancy in months.
To make the correct calculations, translate weeks into months, you need to know a few features. Doctors always take a calendar month equal to 4 weeks, while the number of days in it is 30. Based on this information, you can calculate: 8 weeks of pregnancy - the end of the second month. The first trimester overstepped his equator, 2 months of pregnancy is over, the third begins.

Venous blood begins to circulate separately from the arterial blood. There are also changes in the urinary system - the fetus has a permanent kidney. Previously, it was the primary organ that is now divided and gives rise to two systems simultaneously: the sexual and urinary.
The sex rollers continue to differentiate and form the rudiments of the external genitalia. This occurs under the influence of the synthesis of sex hormones, which produces the adrenal cortex. The female ovaries form in the female fetus, and an ovarian reserve is laid in their cortex-1 million follicles, from which, after puberty, oocytes begin to emerge. In the body of a male fetus under the influence of testosterone, the testes form.
Term of 8 weeks of pregnancy is the size of the fetus
The baby at the 8th week of pregnancy is still very small, so you can determine its size only with the help of ultrasound with higher resolution. The size of the fetus at 8 weeks of pregnancy should normally be 32-35 mm. These values are more informative. In practice, they may differ in greater or lesser extent. This is determined by the rate of individual development of the baby.
The weight of the fetus on the 8th week of pregnancy is no more than 5 g. It should be noted that the values of anthropometric parameters throughout the period of pregnancy are affected by several factors:
- heredity;
- the future mother's diet;
- the rate of metabolic processes in the body of the baby.

The organ of separation and gas exchange in the child (allantois) begins to be reduced along with the yolk sac, they enter with the umbilical cord. This anatomical formation plays an important role in making the connection between the mother and the fetus.
What does the fetus look like on the 8th week of pregnancy?

The growth of the organ is observed in the region of the bottom, which gradually begins to rise. At this time, she still does not leave the small pelvis, so it is impossible to palpate the enlarged uterus through the abdominal wall. The belly does not change outwardly, so the surrounding people do not know about the position of the woman.
Allocations at week 8 of pregnancy

It is necessary to pay attention to the nature of painful sensations - the appearance of cramping pain can be a sign of a threat of miscarriage .
Ultrasound at week 8 of pregnancy
