The second month of pregnancy begins with the fifth week. In this period the length of the embryo is already 7.5 centimeters. During the second month of intrauterine development, the central nervous system, the brain, the spine, and the sexual glands of the future child are formed. During this period, the liver and thyroid gland also develop. Therefore, it is very important already during this period of pregnancy to pay special attention to the diet. Include in the diet foods containing iodine, which is necessary for the formation of the thyroid gland.
In the second month of pregnancy, the fetal head is located much closer to the trunk, it is tilted to the chest. Already from 31-32 days there are rudiments of hands and feet that resemble fins. In the sixth week, the beginnings of the future eye are formed. Ears appear on the head of the embryo. In addition, the abdominal cavity is formed in the sixth week, the heart and the circulatory system function.
During the seventh week of intrauterine development, the processes of organogenesis are being carried out more and more intensively. Developed and improved bodies established in previous weeks. Of the blood vessels of the embryo, one is released, which is between the embryo and the placenta. Subsequently, he is transformed into the main link between mother and child - the placenta. Also during this period, fingers are formed on the handles, which are still quite short and thick. The length of the embryo by the end of the seventh week is already 12-15 cm. As you can see, in two weeks it almost doubled.
Since the eighth week, the embryo begins to grow rapidly, most organs have already been formed, so their active growth and development is taking place. The future child already has a face: mouth, nose, ears. In addition, there is a marked difference in the structure of the genital organs. The head of the embryo is almost equal to the length of the trunk. From this period the embryo becomes a fruit. Its length is approximately 20-30 mm, and weight - 13 grams.
It is interesting to know that in the second month of intrauterine development the entire bone-joint system of the fetus actively develops, the trunk is formed and lengthens. Eyelids appear on the eyes of the fetus. He already knows how to open his mouth, and also to move his fingers. The legs of the fetus touch. During this period, the large intestine begins to perform its contractile function.
What affects who will be, boy or girl
And the whole thing in genetics ... Human sex cells contain 23 pairs of chromosomes, in contrast to all other cells, which consist of 46 chromosomes. Chromosomes from the first to the twenty second pair of the same shape. These are somatic chromosomes. But the chromosomes of the 23rd pair are the same only in women. This is the chromosome XX. In men, however, the chromosomes of this pair are different, therefore they are designated as XY chromosomes. So, if the egg fertilizes the X-spermatozoon, the girl "gets", and if the Y-sperm fertilizes, it means waiting for the boy.
Feelings of a pregnant woman
I think most women, starting from the second month of pregnancy, "dipped" into the world of new sensations. You have not only stopped menstruation, but there may be a toxicosis of pregnancy, manifested by nausea and vomiting, as a reaction to food and smells. Headaches, drowsiness, periodic dizziness, mild weakness may occur. By the end of the second month of pregnancy a woman can feel even the narrowness of clothing around her waist. During this period, there may be addictions to some food, craving for sour, salty or sweet. I remember myself, how I really really wanted meat, and generally eat.
Such new changes in the body are the result of adaptation to a new "interesting situation". Some emotional changes may also appear, such as: resentment, irritability, feelings of anxiety, mood swings.
The second month of pregnancy is a kind of transition period, when a woman should reconsider her way of life, nutrition, working regime, etc. For the beneficial development of the fetus in the second month of pregnancy, it is necessary to exclude the effect of various harmful factors. The best option is to take a couple of weeks off to relax and take a walk in the fresh air. If you have not yet become registered in the women's consultation, now is the time to go to the gynecologist. He will give useful recommendations on nutrition, prescribe all the necessary tests and answer the questions that interest you.
