Very often, pregnant women are confused and cannot understand what week the 3rd trimester begins with. Sometimes doubts relate to its duration and current events.
How to determine the 3rd trimester of pregnancy?
Very often, expectant mothers are perplexed, because they do not know what week the 3rd trimester of pregnancy begins with. There are several variations, according to which this period falls on different periods.
But at the heart of the separation of pregnancy into periods lies a single principle. In the first trimester, important organs and systems begin to form in the fetus. In the second, he is improving and growing. 6 months of pregnancy completes this trimester, and the woman begins to feel that she will soon become a mother. The first movements and tremors of the child occur in the third trimester. During this period, the baby mainly gains fat mass, his body systems are endowed with important qualities that can ensure viability in the first weeks after birth.
Some classifications claim that the beginning of the 3rd trimester is compared with the 24th week. Others begin the countdown of this period from the 26th and even the 28th week.
Now doctors rarely calculate trimesters, preferring to use only a week for counting.
How long does the 3rd trimester last?
The onset of labor for every woman depends entirely on her body. Some are pregnant, others give birth prematurely. And all this is considered to be the norm.
Do not forget that doctors can only approximately determine the period of conception. But be that as it may, with what week the 3rd trimester begins, it still remains an open question. It is important that normally this period lasts at least 12 and no more than 16 weeks.
The final stage of pregnancy should not end earlier than the due date, therefore it is important to follow the recommendations of doctors, often to be in the fresh air, eat a balanced diet and exclude physical and emotional stress.
Regular consultations with your supervisor will help you quickly get rid of your health problems.
What happens in the 3rd trimester?
You already know when the 3rd trimester of pregnancy begins, so it's time to talk about what happens during this period with the expectant mother. The preceding final stage of 6 months of pregnancy forms a stable emotional state of a woman. As a rule, appetite preferences remain stable, the probability of developing a depressive state decreases, and increased fatigue disappears.
An important stage of the last trimester is maternity leave. By this time, it becomes more difficult for a woman to do the usual work, so she should rest more.
After the onset of the third trimester, expectant mothers begin to actively add pounds. During this period, you need to carefully monitor your own nutrition, because excess fat will be deposited in both the woman and the baby.
The large weight of the child can significantly complicate the birth, and sometimes cause a cesarean section. Also, overweight often causes veins and hypertension.
Third trimester: processes in the female body
At the beginning of this period, the distance from the bottom of the uterus to the navel is 2-3 cm. Gradually, the uterus begins to compress the internal organs of the female body and shift them up. As a result, diaphragm movements are disturbed, there is a feeling of discomfort under the ribs, shortness of breath and shortness of breath when walking.
At this time, a woman weekly collects 400 g. Closer to the end of the 7th month, expectant mothers first encounter training contractions, which are most often painless. A large belly can cause insomnia, so it’s best to immediately learn to sleep on your side.
Signs that a pregnant woman can detect during this period:
· increased discharge;
· digestive system problems;
· sprain of the lower abdomen, pain;
· colostrum discharge from the chest;
· vomiting and nausea;
· training fights;
· spasms in the calf;
· active fetal behavior;
· awkward gestures.
Nutrition in the 3rd trimester of pregnancy
At this time, more than ever, it is important to eat right. Experts say that a balanced meal significantly reduces the likelihood of developing gestosis. Every expectant mother is able to abide by the rules that will help her and her baby.
Lean fish and meat should be included in the diet, but these foods should not be eaten in the evening. It’s worth completely forgetting about chocolate, nuts, citrus fruits, spicy, sour, fried dishes, preservation.
But meals in the 3rd trimester should not be limited. Do not lean on sweet and flour dishes, you should give preference to vegetables and cereals. Fiber, which is contained in these categories of products, will help normalize digestion and give a feeling of satiety for a long time.
Norms of fetal development during this period
During the course of pregnancy, the expectant mother undergoes a lot of procedures that allow you to track the condition of the fetus and the level of its development, including ultrasound. The third trimester is final, and this study is very important. Ultrasound diagnostics is a way to detect severe violations of the fetal development, it is carried out in conjunction with the delivery of tests for hormones.
The objectives of the third routine screening
Ultrasound helps to study the position of the fetus in the womb. 3rd trimester is a difficult period in pregnancy, so it is so important to play safe and pre-determine the birth management strategy that will be used.
Ultrasound examination of the fetus allows you to clarify its anatomical parameters: approximate weight, size, compliance with the current stage of pregnancy. It is important not only to know from which week the 3rd trimester begins, but also to fix defects, infections that were not detected earlier.
Last trimester screening provides data on changes in the cerebral cortex. In addition, this procedure is used to measure the volume of amniotic fluid and exclude possible complications during childbirth.
It is very important to undergo timely examinations prescribed by the attending doctor. Consistency is not a doctor’s whim, but a vital necessity for both a pregnant woman and a baby. Stressful situations and poor environmental conditions are adverse external conditions that adversely affect the health of expectant mothers and their children.
Deviation of water volumes may indicate significant changes in the anatomy of a developing child. Ultrasound examination is also a chance to detect complications that may interfere with the natural birth. We are talking about the development of neoplasms, cervical insolvency.
A pregnant woman should first of all think about the baby, so it is so important to eat right, not to worry and go through the procedures prescribed by the doctor.
