Height - from 1.6 to 2.2 cm, weight - about 1 g.
Your baby has grown to the size of a small olive tree and is already beginning to resemble a real man. Every minute, a child develops 100 thousand new nerve cells, they come into contact with each other and form the beginning of the pathways. Five primary brain regions have already been created, although ultrasound shows that the child's skull is still completely transparent.
The placenta is formed and the umbilical cord departs from it. The common arterial trunk is divided into the aorta and pulmonary artery. A second septum appears in the heart, dividing the left and right ventricles. Together with the atrial septum, they create the first valve. From this time on, blood flow is possible only in one direction - from the right atrium to the left. The heart rate is 112-136 beats per minute.
The rudiments of the gill slits atrophy; the elbow and wrist are visible on the arms, and the knee joint on the legs. On the foot, the fingers have finally formed, and on the hands they have become longer. Long bones, axial skeleton and skull gradually ossify. The head of the fetus, jaw and neck are clearly defined. The ears are visible on the head, the eyelids almost completely cover the eyes, the nostrils stand out. The place where the genitals are located is clearly visible on the ultrasound, but it is still impossible to determine the sex of the child.
This week, the central lymphatic organ - the thymus (or thymus) - is laid, the first follicles appear in the thyroid tissue, and in addition, the epidermis becomes more complicated - your baby's skin already consists of 2 (!) Layers of cells. The stomach shifts and takes its place in the abdominal cavity.
The muscle layer of the stomach acquires nerve elements, which subsequently cause the stomach and intestines to contract for the proper passage of food. The future salivary glands and taste buds arise, which are associated with nerve cells in the brain stem. The muscles of the mouth, pharynx, and neck gradually appear so that the baby can swallow and chew after birth.
In the future nose of the baby, receptors appear that are responsible for the sense of smell. But they will not function for a long time, because the baby cannot breathe in the amniotic fluid that surrounds him. Therefore, his nose is still closed with a mucous plug. The child is quite actively moving, although the mother does not yet feel it.
Now is the right time to pay a visit to the doctor and register with the antenatal clinic. It is advisable to do this before the 12th week of pregnancy.
You should take a clean diaper with you to the appointment (normal or disposable), and if you or your husband are sick or ill with something (tuberculosis, rubella, hepatitis, sexually transmitted diseases, diseases of the cardiovascular system, spine, etc.), then it is advisable to take with you either a medical record or an extract from your doctor. The obstetrician-gynecologist should know what treatment is indicated for you, in case of any complications, he will be able to determine the best way for you to manage your pregnancy. Do not forget your medical insurance policy and passport.
At the first appointment, the doctor will fill out a special card for you, where data about your age, height, weight, constitution will be entered, whether the pregnancies were noted earlier and how they ended, what diseases you suffered, whether there are pathologies, etc. If you are worried about something, if you have had an unsuccessful pregnancy or other reasons to fear for the normal development of your child, be sure to report it.
The doctor will weigh you, measure the circumference of your waist and hips, and conduct a gynecological examination. Your smears will be taken for the presence of mycoplasma, ureaplasma, group A and B streptococci, gonococci, syphilis, etc.
If your pregnancy has not yet been established, then you will be sent to donate blood to determine the level of hCG and ultrasound. In addition, your doctor will give you a referral for the following tests:
- general urine analysis.
- blood biochemistry (ALT, AST, bilirubin, glucose, GGT creatinine, total calcium, potassium, urea, sodium, TIBSS, transferrin, ferritin, alkaline phosphatase) - taken from a vein strictly on an empty stomach;
- blood group and Rh factor, antibodies to Rh factor (the analysis is always carried out, regardless of whether you know your blood group and Rh factor or not) - taken from a vein strictly on an empty stomach;
- clinical blood test - taken from the finger;
- analysis for infections (toxoplasmosis, rubella, cytomegalovirus, herpes simplex 1 and 2 types, parvovirus B19) - taken from a vein strictly on an empty stomach;
- analysis for AIDS and HIV - taken from a vein strictly on an empty stomach;
- analysis for hepatitis B and C - taken from a vein strictly on an empty stomach.
The list seems long, but in fact it is enough to donate blood once from a finger and once from a vein. Very often it seems painful for pregnant women to donate blood from a vein in the morning and strictly on an empty stomach. If it is very difficult for you not to eat in the morning, then in extreme cases, you can drink unsweetened tea and eat a cracker. You can not eat sweet, spicy, salty, fatty, drink coffee, especially in large quantities. This breakfast can significantly affect the accuracy of the analyzes. Tea and crackers will back up you for a couple of hours and won't do much damage to accuracy. In addition to tests in the first trimester of pregnancy, you need to be examined by a therapist, dentist, ophthalmologist, endocrinologist, and otolaryngologist.
The further schedule of planned visits to the doctor is as follows:
- at least once every 4 weeks until the 20th week of pregnancy;
- at least once every 2 weeks from 20 to 30 weeks of pregnancy;
- at least once a week from the 30th week of pregnancy until delivery.
However, there is no rigid schedule. If you feel unwell or are worried about something, then you can see a doctor at any time. Your uterus began to grow: if before it was the size of a fist, now it is about the size of a grapefruit.
Favorite things have become a little tight at the waist, but so far nothing is noticeable to outsiders. This is terribly offensive and inconvenient. Because toxicosis and dizziness torment you terribly, and no one concedes a place in transport - after all, the pregnant tummy is still invisible.
Mood swings can become very noticeable. Try to keep yourself in control and do not limp. It's not as bad as you might think. It's just your body's reaction to pregnancy.
Your skin may suddenly become covered with pimples or, conversely, become dry and irritated, try the following:
- exclude flour, sweet, fatty foods from your menu;
- drink more water;
- cleanse your face with a good tonic 2-3 times a day;
- walk more and stay in the clean fresh air. You can put a special humidifier in the house, or, in extreme cases, just keep a bucket of water in the room;
- if all else fails, consult a doctor. It is possible that vitamins or other medications that you take in connection with pregnancy give this effect. You can try changing the drug.
7 week - 8 week - 9 week
