Height - 3.1-3.9 cm, weight - 5-9 grams.
By the end of this week, the baby will no longer be called an embryo, but a fetus. In the future, they will only grow and prepare for extrauterine life.
A critical stage has been passed - at the embryonic stage of development, the child is too susceptible to external factors, which in some cases leads to the development of congenital defects. The fetus is protected from this danger: most malformations could form only before 10 weeks. In the future, drugs and starvation of the mother remain negative factors.
In the meantime, the baby is in the mother's tummy, he tries to get comfortable. And the placenta helps him a lot in this. The placenta is an amazing organ that is a kitchen, a bathroom, and an air conditioner for a baby. From the 12th week of pregnancy, the placenta will be finally formed and will completely take over the provision of the child with everything necessary.
The baby grows inside the fetal bladder, which contains a clear amniotic fluid with a volume of about 20 ml. The baby is connected to the placenta by the umbilical cord, through which nutrients are supplied to him.
The kidneys take their place in his body and begin to gradually filter out substances unnecessary for the child's body from the blood and remove them. Finally, it removes these waste products from the placenta, working together with the mother's kidneys. Therefore, the mother now needs to carefully monitor her genitourinary system and at the first signs of a malfunction of the kidneys (swelling, pain, discomfort when visiting the toilet), immediately consult a doctor.
The child's head straightens more and more. She already has a completely human face with correctly set eyes, shaped ears, nose and mouth. The brain develops at a tremendous speed: every minute 250 thousand new neurons appear, and the volume of the bone marrow grows to 16 ml.
The first cells responsible for immunity, the so-called lymphocytes, are already functioning in the blood. The child's skeleton is already completely human and well-defined. The kid can even connect the pens to each other.
The respiratory system is so developed that it is already ready for the first entry. True, the time for him will not come soon. At 10 weeks, with a great desire and good technique, you can examine the genitals and find out who will be born to you: a boy or a girl. But the probability of error is still very high. If you have a boy, he is already starting to produce the male hormone testosterone.
Interestingly, the baby begins to react to what is happening around, for example, to the movements of the umbilical cord, fluctuations in the amniotic fluid, movements of his own arms and legs. The child marks all events with primitive facial expressions.
Your weight is gradually increasing at an average rate of 250 grams per week. By week 12, an increase of 2 kg is considered ideal. However, there are no clear rules according to which weight should be increased. It mainly depends on the constitution of the woman. Some gain at once and a lot, some gain very little, and some even lose weight.
There have been examples when women with impaired metabolism and excessive obesity during pregnancy suddenly healed and returned to their ideal weight. Therefore, we can conclude that the female body knows when, where and how much to add so that the child develops optimally. Of course, if he is not interfered with by improper nutrition and diets.
On average, during pregnancy, a woman gains weight by 12-16 kg. In a modern society focused on an uncompromising struggle with every additional gram, the figure of fifteen pounds looks terrifying. But don't be alarmed. In fact, you will lose more than half during childbirth, and the rest will almost completely disappear from you during the first two months after the hospital (unless, of course, you start to eat sweets).
In the first trimester, the increase is 1-2 kg. In the second trimester - 6-7 kg. In the third trimester - 4-5 kg. Growth rate from 200 to 500 grams per week.
The acquired weight at the time of delivery is distributed in the body like this:
Child - 3.0-3.5 kg.
Adipose tissue and nutrients - 3.5 kg.
Cellular fluid - 1.5-1.8 kg.
Increased blood volume of the uterus - 1.2 kg.
Uterus enlargement - 0.9-1.0 kg.
Amniotic fluid - 0.9 kg.
Placenta - 0.7 kg.
Breast and mammary glands - 0.5-0.9 kg.
Your heart is working hard. The frequency of contractions can rise up to 100. These are acceptable values, but if your heart rate is too fast, you need to visit a cardiologist. Now a big load is falling on your heart - it pumps blood for two at once, by the time of birth it will pump 6 liters of blood per minute!
In addition, your blood is now undergoing a change. It is actively producing plasma and red blood cells. Plasma formation is usually faster. Therefore, many may face such a problem as anemia.
If in your blood test the hemoglobin level drops significantly below 100, you should take measures to restore it (vitamins (zinc, iron, folic acid), special food (pomegranate juice, spinach, liver, meat)), and if the drop reaches 37, then we can talk about anemia and require special treatment.
You need to take this seriously as it is the red blood cells that provide you and your baby with oxygen. Anemia is one of the most common causes of death for women and children. It should be remembered that during childbirth, you can lose from 450 to 900 liters of blood at the most favorable rate. And with any complication, blood loss increases, which in case of anemia is fraught with serious consequences, up to emergency resuscitation and blood transfusions.
Other unpleasant problems during this period include constipation, hemorrhoids and sciatic nerve irritation. Constipation leads to excessive tension in the lower abdominal muscles and also contributes to the formation of hemorrhoids.
For prevention, you should lead a more mobile lifestyle (important for those who work in the office), drink more water and more, eat special natural laxatives (prunes, dried apricots, wheat bran). Other methods of treatment are strictly discussed with the doctor so as not to provoke a miscarriage.
Irritation of the sciatic nerve is very unpleasant: a woman experiences pain in the back, buttocks, hips, legs. The pain is caused by the expanding uterus pressing on a nerve that runs just behind it into the legs. For relief, lie down slightly on the side opposite to where the pain is felt.
If it does not help, you can use different ointments, such as "Voltaren emulgel", but you must definitely see a neurologist. Firstly, pain may indicate more serious inflammation than just irritation of the nerve, secondly, it is necessary to develop a treatment, and thirdly, it is necessary to monitor before delivery in order to develop the correct strategy for pain relief.
