Eleventh week of pregnancy

Future child.

Height – 4-6 cm, weight – 7-11 g.

From this week on, your future baby is no longer called an embryo, but a fruit. This means that all the main bodies in it have already been laid, then only their growth and development will occur.

The baby is the size of a small lemon in size. Over the next three weeks, its growth will double. While half of the body is the head of the child, because his brain develops at a fantastic speed. The legs are also noticeably shorter than the handles. But all these disproportions will be smoothed out at the moment of birth.

This week will finally form a sternum, fingers and feet continue to develop and gradually acquire nails.

The eyes of the child receive the iris – that is, the “colored” part of the eyeball. Now the kid already knows exactly what color he will have eyes at birth, but, unfortunately, future parents and even doctors are unlikely to see this on ultrasound.

The placenta builds up the number of blood vessels so that the child receives as many substances as it needs. Part of the baby’s intestines can still fall into the umbilical cord, but in the next few weeks it will take the right position. The intestine is already beginning to make cuts, although it has nothing to digest yet.

Soon, thanks to these reductions, the amniotic fluid and dead cells will be discharged through the intestine. The kidneys also work actively and filter blood, although the biochemical balance of the system is now handled by the placenta. Thymus – the central immune organ – actively synthesizes thymocytes, the first lymphatic vessels appear (next to the lungs), primitive hemoglobin appears in the blood.

The central organ of the endocrine system, the pituitary gland, begins to work. This gland, the size of a pea, is located in a special place between the bones of the skull – the so-called “Turkish saddle”. The pituitary gland produces hormones that affect metabolism, growth and reproductive function. In addition, the pituitary gland produces a thyroid-stimulating hormone, which contributes to the development of thyroid tissue.

It is still impossible to see exactly who will be born – a boy or a girl. The final formation of the genitals will be completed a little later. But quite often experienced doctors can correctly determine the future sex of the child according to ultrasound from 11-12 weeks.

The kid develops the sense of smell, the vocal cords are formed, there is sensitivity at the palms and a grasping reflex. He has already found many interesting activities. For example, a child can stretch, turn and very quickly change the position of the body, helping himself with legs.

The Kid loves to bend, unbend the back, wag his arms, kick his legs – in general, he already has a full set of qualities that lead to the affection of all moms in the world. So he can practice for 7 minutes in a row. And the longest rest that he allows himself, lasts only 5.5 minutes.

Future Mom.

The main thing that you should do at 11 – 12 weeks of pregnancy, is to pass the next tests. A clinical blood test and a urine test are resubmitted (if your doctor deems it necessary), ultrasound and a double test are added to them. The aim of the tests is to identify early fetal pathologies, if any.

A double test is a screening of blood for the detection of such pathologies as Down’s syndrome (dementia), Edwards syndrome (oligophrenia), Patau syndrome and some others. All of them arise as a result of changes in chromosomes (21, 18 and 13, respectively). Unfortunately, it is impossible to cure chromosomal pathologies, so many women decide to terminate their pregnancy.

You need to know that children with Down’s syndrome are quite viable, despite their dementia, but their life expectancy is much less than that of a healthy person. Children with Edwards and Patau syndrome only survive up to 1 year in only 5% of cases, and then live very briefly.

For the detection of syndromes, a blood test from a vein of 2 markers is taken: a free beta-hCG subunit and a PAPR-A protein (plasma protein A).This test in combination with ultrasound gives an accuracy of 85%.

The results of the analysis are often presented in MoM units (the ratio of the serum content in a woman’s blood to the average for this week). If everything is normal, then MoM should be close to unity. Congenital malformations are indicated by significant deviations from the unit in one direction or another.

But it should be remembered that smoking, the body weight of the patient (if it deviates significantly from the norm), ECO, race, inaccurate information about the date of the onset of pregnancy and the undiscovered yet multiple pregnancy contribute also to a significant discrepancy in the indices.

The blood test is supplemented with an ultrasound examination of the collar zone of the fetus (otherwise the width of the cervical transparency or neck cuff). It is not measured before 10-11 week. Optimum to do ultrasound from 11 weeks to 13 weeks and 6 days of pregnancy (coccyx-parietal fetal size from 45 to 84 mm).

The aim of ultrasound is to measure the accumulation of subcutaneous fluid on the back surface of the baby’s neck. The main marker is the width of the cervical transparency. In this case, if the baby unbends the head, then this value can increase by 0.6 mm, and if it bends, it decreases by 0.4 mm.

The threshold value is 3 mm. Large numbers cause suspicion of an anomaly, especially if there are other signs:
– nasal bone (60-70% Down’s syndrome) is not detected;
– disturbance of blood flow in the arancy duct (80% Down’s syndrome);
– megacystitis (an increase in the size of the bladder);
– moderate tachycardia;
– reduction of the upper jaw;
– as well as blood test data.

If all these factors are unfavorable even after re-taking the blood test and ultrasound, another test is being done, which is currently considered almost obsolete – a biopsy of the villus of the chorion. Through the incision in the abdominal cavity of the mother or through the cervix, a tool is inserted into the inside, which takes a sample of tissues.

Similar analysis – amniocentesis (puncture of the bladder). There is a risk of miscarriages, but a small one (1-2%). It is now believed that the markers for beta-hCG and PAPP-A give data not less accurate than biopsy and amniocentesis, but the risk of miscarriage is 0%.

There is not a single woman who does not worry when passing such tests. And ahead is a triple test at 15-16 weeks and the same excitement. Try not to be nervous, now it is contraindicated. It is better to get pleasure from the first “full-time” acquaintance with the baby.

On the ultrasound screen you can see your little man in some detail. Distract yourself from unpleasant thoughts – ask the doctor to print out the first “photo” of the baby, talk about whether anyone is visible there, a boy or a girl. Relax, because the chance that your child develops chromosomal abnormalities is really not great.

In everyday life, you should pay attention to your hair and nails. It’s good if they somehow strengthen you and start to grow well. But most often on the contrary – the hair is split and falls out, the nails are broken.

If you think that the situation is alarming, pay attention to your diet and vitamins and check with your doctor. We recommend eating more dairy and curd products – and for the baby it’s also useful for your beauty.

Similar processes occur with the teeth, so do not forget to visit the dentist. At the reception, tell him that you are pregnant, it affects what kind of anesthesia he will apply. Brush your teeth at least 2 times a day, and preferably and more often. Vitamins containing fluorine, phosphorus and calcium, and also ascorbic acid will help you.

10 week – 11 week – 12 week
