At the 10th week of pregnancy, the most critical stage of embryo development ends. The formation of internal organs is completed, the active development of the central nervous system continues. The condition of a pregnant woman does not practically change and remains the same as in the first weeks after conceiving a child.
The baby is actively growing, and at 10 obstetric weeks its growth is about 5 cm. The weight of the embryo is within 4-6 g. During this period, almost all internal organs are formed in the embryo. The four-chamber heart of the baby knocks at a speed of 160-180 beats per minute. The kidneys function, producing the first portions of urine. Foci of blood formation appear in the liver and red blood cells (erythrocytes) are formed.
At the 10th week of pregnancy, the formation of the chest cavity begins. The trachea is separated from the esophagus, which in turn connects to the stomach and oral cavity. The embryo’s stomach is still not working, and the baby receives all the nutrients through the blood from the mother.
Week 10 is marked by active development of the central nervous system. At this time, the hemispheres are differentiated, the middle and the medulla are separated. Connections between neurons are formed, the first reflexes appear. At the same time, the baby begins to move in the amniotic fluid, occasionally touching the uterus walls with the arms and legs. To feel the movement of the embryo at 10 weeks is still impossible.
At week 10, the development of the placenta continues. This body gradually takes over all the work on nutrition and protection of the embryo from external influences. The yellow body is losing ground. Soon, the placenta will produce progesterone, which is necessary for the normal course of pregnancy.
Condition of a mom
10 obstetric week has the peak production of the hormone HCG. In this regard, all the subjective signs of pregnancy become the most pronounced. Toxicosis continues to trouble the expectant mother. Many women at this time report increased daily nausea and vomiting. This condition is considered perfectly normal and is not a cause for particular concern.
At the end of the first trimester, marked mood swings persist. Remains intolerance of strong odors and addiction to unusual food. Often, future mothers complain of weakness and fatigue. Some women have excessive salivation.
10 week increases the frequency of urination. The desire to visit the toilet room can occur every two hours. The portions of urine may be quite small. Frequent urination should not be accompanied by pain, itching, or burning. Otherwise, you should definitely be examined by a urologist.
At 10 weeks, the total weight gain ranges from 0.5 to 2 kg and depends on the severity of toxicosis. Some women at this time lose weight due to constant nausea and vomiting. Outlines of a figure practically do not change, the tummy remains flat. Even the most attentive observer is unable to notice the changes that have occurred during this period of pregnancy.
At the 10th obstetric week, abundant vaginal discharge is preserved. The discharge may be clear or milky — both of these options are considered normal. The appearance of yellow, green or cheesy discharge indicates the development of infection. Bleeding from the genital tract occurs when miscarriage or regressive pregnancy begins.
