Menstruation

Today your menstrual bleeding started.

Conception

Conception.

1 week

Of course, this is not yet pregnancy, as you have another menstrual bleeding. However, whether you want it or not, the body has started preparing for possible motherhood again.

2 weeks
Most often, a woman becomes pregnant in the middle of the cycle, on the 14th day.
3 weeks
A few days after fertilization, to the inner wall of the uterus (endometrium) the embryo-morula attaches. Now you are officially pregnant!
4 weeks
You can use a home urine HCG test, but it is not very reliable, as the term is very small.
5 weeks
The first suspicion that you are pregnant arises when your period does not arrive, which happens 2-3 weeks after conception.
6 weeks
For many women, pregnancy is associated with malaise and nausea. But in the initial weeks of pregnancy, you may not feel any discomfort at all.
7 weeks
Five weeks after conception, the gestational sac attaches to the uterine wall. The cervix is usually relaxed; however, at such an early stage, doctors do not yet examine the pregnant woman on the chair. Nausea and other manifestations of toxicosis are felt.
8 weeks
Your uterus has started to enlarge, but it is not yet noticeable. Your gynecologist can determine this during the examination, and you might too - your clothes have become slightly tight.
9 weeks
You still can't tell you're pregnant by your figure. The blood does not yet have the highest level of chorionic hormone, but you already feel a change: the skin has become smoother and more even, although acne is not excluded.
10 weeks
High hormone content affects your mood and well-being. Increased excitability and mood swings are observed. Physically - you start gaining weight, gums become loose, and the thyroid gland is slightly enlarged.
11 weeks
Now you burn calories faster than before pregnancy: metabolism increases by 25 %. The volume of circulating blood also increases. You feel internal heat, drink a lot of fluid, and sweat profusely.
12 weeks
Your uterus has increased in width by about 10 cm. It is becoming cramped in the pelvic area and rises into the abdominal cavity. Using ultrasound, the doctor can more accurately determine your due date by the size of the fetus.
13 weeks
By now, your blood already contains a lot of hormones responsible for pregnancy. Soon morning sickness will stop bothering you, and you will become less irritable. The feeling of anxiety related to the risk of miscarriage will subside. It is necessary to be especially careful about the prevention of viral diseases.
14 weeks
You have entered the second trimester, the best time of your pregnancy. Now you will feel more energetic, although your uterus increases every week. You will notice this yourself when your belly starts to rise: if earlier the bottom of the uterus (its upper part) was above the pubic area, now it is already above the navel area.
15 weeks
If you carefully feel the abdomen, you will feel that the upper edge of the uterus (the bottom of the uterus) is located about 7.5 cm below the navel level. The hormones actively secreted by the fetus can affect your body, causing, among other things, severe hair loss.
16 weeks
Your uterus expands, giving space to the growing fetus in the placenta. The amount of amniotic fluid at this stage is about 250 ml.
17 weeks
The fetus develops rapidly, and the placenta keeps up with it. If in the early weeks it was a thin membrane with chorionic villi, by the end of the term it is a dense (thickness of about 2.5 cm) mass, weighing 480 g.
18 weeks
If this is your first pregnancy, the 18th week is especially exciting for you because you start feeling the baby move. However, many young mothers will experience this joy only at the 19-20th week, especially if they are gaining extra weight.
19 weeks
The main achievement of the week is the continuing growth of the brain. The disproportionately large head of the embryo is a sign of the important role the brain plays in the child's development.
20 weeks
18 weeks have passed since conception, and your belly and pregnancy are already noticeable. Your waist is not a waist but a belly like a bun. The upper edge of the uterus is slightly below the navel level.
21 weeks
In your child's blood, there is already a fairly high content of red blood cells: white blood cells, responsible for suppressing infections, begin to be produced. Taste buds start to form on the tongue.
22 weeks
As in previous weeks, your blood volume increases, mostly due to plasma. Plasma is the liquid component of the blood, capable of dissolving blood cells. This is why many pregnant women are found to have physiological anemia.
23 weeks
Despite the fact that the child begins to rapidly gain fat, he still looks red and wrinkled. This happens because the skin forms much faster than sufficient fat deposits can form under it, so the skin is still saggy.
24 weeks
Weight gain starts to show. Hence - headaches, bladder problems, heaviness in the legs, and general fatigue.
25 weeks
Your uterus has now increased to the size of a football, already pressing on the diaphragm, under the ribs, and shifting the stomach.
26 weeks
This week the baby is already starting to open his eyes slightly. By this time, they are almost fully formed, all layers of the eyeball are now exactly the same as they will be at birth.
27 weeks
From this week, the baby's chances of survival in case of premature birth are 85%. So from now on, the baby already has quite real viability. However, there are 13 full weeks left until the full gestation of the fetus; the baby is still not fully developed, so in the event of premature birth, many problems will arise that will need to be addressed.
28 weeks
If the baby is born this week, legally he will be considered a human being subject to registration. The cerebral cortex has developed convolutions, and the mass of the brain continues to increase. The hair on the head is getting longer.
29 weeks
By this time colostrum or "first milk". This sticky watery liquid will be the first food for the baby, just brought into the world.
30 weeks
As you gain weight, your movements become slower and clumsier. Do not forget about proper posture when walking or sitting. Before getting up from the bed, first roll onto your side. Back pain, which appears due to a heavy load on the back, makes itself felt.
31 weeks
In the later stages of pregnancy, back pain is almost inevitable. The reason is that the ligaments and muscles of the back are now resting, relaxing, preparing for the birthing process. Vein expansion in the legs is also very likely now.
32 weeks
In the later stages of pregnancy, the child hears perfectly what is happening around. He recognizes the sound of your heartbeat, is familiar with the sounds of peristalsis, and the noise of blood flowing through the umbilical cord.
33 weeks
By this time, the child has already turned head down: he is preparing for birth. Your doctor or midwife will tell you about the position of your fetus in relation to the birth canal.
34 weeks
Braxton Hicks contractions become more regular. These are cramping painful sensations that appear in the upper part of the uterus, then spread downward and finally subside.
35 weeks

This week, the baby's nails have already grown to the very edge of the fingers. On the day of birth, he may have long nails: there may be scratches on his face that he got while in the womb. Now it is cramped and uncomfortable for him there.

36 weeks
His face has become plump and smooth: chubby cheeks have appeared. Baby cheeks are due to the accumulation of subcutaneous fat plus intense finger sucking in the womb for several months - a great workout for the sucking muscles!
37 weeks
This week, or a little later, if this is not your first pregnancy, the precursors of labor will appear. This means that the baby's head (in case of cephalic presentation) descends into the pelvic area. You may feel some relief as the pressure on the internal organs eases.
38 weeks

In the last week, the baby has accumulated a lot of waste products in the intestines. This black-green substance is called meconium and consists of disintegrated blood cells, dead intestinal cells, as well as exfoliated skin cells, fetal lanugo hair swallowed along with amniotic fluid, and other components.
39 weeks
The cervix is now shortening and opening, and the bladder is under the most pressure it has experienced during pregnancy. Some nervousness might appear on the eve of now imminent labor.
40 weeks
Awaiting the onset of labor, try to remain calm.  When real contractions start, make sure those around you are aware of your plans on where and how to give birth. During contractions  do not forget about relaxation techniques and proper breathing.
41 weeks
If the baby is still in the uterus, he is simply gaining weight and possibly worrying that "he's overdue". If he is already born, he is obviously amazed at how much his new life differs from the previous, intrauterine one.
42 weeks
Only ten percent of pregnant women "go beyond" the 42nd week. However, do not worry if you are among them. It may well be that your due date was calculated incorrectly, so in fact, you are on the schedule set by nature. Still, talk to your doctor about various methods of labor induction.
43 weeks Post-term pregnancy.
