Let’s see what happens in a woman’s body during pregnancy, and what signs indicate its onset.
It may seem strange, but the pregnancy is counted even before it occurs. Do not be surprised, but the doctor will determine the onset of pregnancy at least two weeks earlier than it could actually occur.
This is due to the fact that in most cases a woman always knows the last date of her period. It was this date that was chosen as the starting point. The most probable possibility of conception is in the middle of the cycle – two weeks after one cycle and two weeks before another. These numbers give us the ability to calculate the estimated due date.
Thus, there are two reference systems for pregnancy: presumptive (gestational) and real (ovulation). Gestational doctors use for safety net, adding 2 weeks to the estimated date of conception. Ovulation is the age of the fetus, which actually takes place. For example, if the doctor gives you 8 weeks of pregnancy, then this means that in fact your fetus is only 6 weeks old. In this case, the gestational age is 8 weeks, the ovulation age is 6 weeks.
Gender depends on the sex chromosome, which is contained in the sperm – the Y chromosome determines the male sex, the X chromosome determines the female sex.
1 month (1-4 weeks)
This is the period when outwardly you do not yet show any signs of pregnancy. During this period, the organs, physiological and functional systems of the child are formed, your body also prepares for bearing the fetus. During this period, pregnancy can be indicated by the absence of menstruation and such early signs of pregnancy as nausea, drowsiness, and increased fatigue.
2 month (5-8 weeks)
There are also no visible changes externally. You may still experience nausea, vomiting, lower abdominal pain. There is an increased appetite and, at the same time, increased fatigue, drowsiness. It is widely believed that pregnant women love pickles. First of all, this is due to the fact that pickles can reduce nausea or eliminate it altogether. You can also reduce nausea by using salted tomatoes, peppers, and other pickles.
3 month (9-12 weeks)
The child undergoes significant changes. All organs are being formed. The body of a pregnant woman also changes. First of all, weight gain occurs. The end of the 12th week marks the end of the first trimester of pregnancy. The most dangerous period is over. Indeed, during this period, there is a high risk of miscarriage. On average, weight gain by the end of the first trimester is 2-3.5 kg. The belly begins to appear. The chest and sides are enlarged. Now you can try on maternity clothes.
4 month (13-17 weeks)
Your baby will already be the size of an open palm. Pregnancy is already noticeable to everyone around you, clothes are tight. We urgently need spacious, comfortable clothes for pregnant women.
5 month (18-22 weeks)
The baby’s weight is about 350 g. Half of the pregnancy is over. Almost nothing bothers me. Pregnancy is now a pleasure.
6 month (22-26 weeks)
You continue to gain weight and increase in size: the fetus, the uterus, the placenta are growing.
7 month (27-31 weeks)
The baby weighs about 1300 g. It is getting harder and harder to wear it. The growing fetus puts significant pressure on the pelvis and stomach. During this period, you need to take special care of yourself, since the risk of premature birth increases.
8 month (32-36 weeks)
Average fetal weight 2.75 kg. You seem incredibly large to yourself.
9 month (36 – 40 weeks)
The kid weighs an average of 3.2-3.4 kg. He acquires the size that he will have at birth. Weight gain doesn’t bother you anymore. It seems that there is nowhere to grow further. The kid has grown, there is nowhere to grow and move. Now you are anxiously awaiting childbirth. Pregnancy is considered delayed if the expected period is more than 42 weeks. In this case, it is already necessary to induce childbirth. It is impossible to postpone a pregnancy, since at a certain period the placenta wears out, ages and ceases to provide a constant supply of the fetus. At the same time, the risk of developing fetal hypoxia and its intrauterine death increases significantly.
