4 week of pregnancy

4 неделя беременности фото At 4 weeks of pregnancy in the body of the future mother, the fetal egg is transformed into an embryo, which is already attached to the uterine wall and completely "buried" into it. The fourth week of pregnancy is very important for the fetus. Right now, embryonic organs (yolk sac, chorion, amnion) develop outside, which provide breathing, nutrition, comprehensive protection and biochemical support for the baby. Chorion participates in the generation of the placenta, and the amnion is the formation of a fetal bladder. In the period of implantation, the outer cells begin to divide and penetrate into the uterine membrane, where expand, resulting in the formation of blood vessels that eventually turn into the placenta. From the embryonic nodule, the body of the future person will form, and already from the surface cells an amniotic fluid, a placenta, an umbilical cord is formed. The placenta will transfer oxygen-enriched blood from the expectant mother to the baby's umbilical vein and take away the slags from the arteries, as well as the decay products. The placenta takes on the functions of the kidneys, lungs, and also the digestive organs and acts as a filter against harmful substances and bacteria. Biologically active elements and hormones are formed in the placenta, which participate in the development of the fetus. The umbilical cord is the connecting link between the child's body and the placenta. The blood flows from mom to baby and back to the pendulum rope. Thus, the future little man arranges a nest and is rapidly developing. At 4 weeks, the future mother begins to understand about the joyful event in her life, because she feels the first signs of pregnancy. , апатия, “металлический” привкус во рту, смена гастрономических пристрастий, учащенные позывы к мочеиспусканию, выделения из влагалища , а также увеличение и повышенная чувствительность груди. Signs of pregnancy at week 4: delay in the menstrual cycle, weakness, drowsiness, dizziness, morning sickness with vomiting, mood swings, unexplained irritability, fatigue, depression , apathy, "metallic" taste in the mouth, changing gastronomical predilections, frequent urge to urinate , vaginal discharge , and increased and increased sensitivity of the breast. All this is a consequence of new enzymes and hormonal adjustment in the body of a future mother, who again talk about the success of conception and the fact of a woman's pregnancy.

And to confirm an interesting situation, carry out a home pregnancy test. It is not difficult. Buy the test at the pharmacy and follow the instructions strictly. In the presence of pregnancy, the test will be positive, because the body has a new hormone - chorionic gonadotropin. It should be noted that the best time for the test is the fifth week, right now the level of the chorionic gonadotropin is higher.

It is important to remember that the first weeks of pregnancy are very responsible and critical in the development of the baby's future.
