Many people are interested in what week of pregnancy the third trimester begins . This is important to know, especially when you consider that this period in itself is very important for the expectant mother. The third trimester is the final feature, which brings a lot of surprises, trouble, and sometimes problems. The baby is about to appear! There is very little left.
What week does the 3rd trimester begin with? What did he cook for the future mother? What should she prepare for? You can find out about all this below. After all, conducting pregnancy is a very important process, especially at the very end and beginning.
Uncertainty
In general, anyone who has ever encountered an “interesting situation” is aware of some of the perplexities of future young mothers who have just registered and are trying to determine which week they are. The thing is that there are two options for the development of events. Which ones?
Interested in what week of pregnancy the third trimester begins? Then consider: your data and doctor's testimony will be different. For about 2 weeks. After all, there is the so-called obstetric and embryonic term. They influence the testimony. So, they won’t coincide. It is difficult to answer which week of pregnancy the 3rd trimester starts from. But probably.
Obstetric
Most often, in order not to confuse and not frighten a woman, it is customary to consider both options. The first thing you should pay attention to the obstetric period. It is extremely important for setting the DA (approximate date when you will have to give birth). Of course, it will be in the third trimester.
The obstetric rate depends on your period. It is counted from the beginning of the last critical days. If you believe this indicator, then you can answer the question of what week the third trimester of pregnancy comes from, without any evidence and doctor’s opinion. What will be the answer? The third trimester is, as you might guess, 27 weeks. It is from this period that you go to the finish line with such a long and important process.
Embryonic
But not everything is as simple as it seems at first glance. It has already been said - there are two options for calculating the gestational age. In the first case, obstetric, you can do without the help of doctors and determine everything yourself. But in the second, embryonic, only a gynecologist's examination, as well as the conclusion of an ultrasound, will give you the result. And accurate.
So, for example, be prepared for the mismatch between the obstetric and fetal gestational age. This is normal, it never happens that they coincide. In practice, the second indicator exceeds the first by approximately 2 weeks. After all, as a rule, conception occurs on the day of ovulation (from here begins the countdown of the development of the embryo). It happens closer to the middle of the cycle, on average after 14 days.
What week of pregnancy begins the 3rd trimester in this case? Only your doctor will answer you, who observes the difference between the obstetric and embryonic periods. But if you take the generally accepted indicators in 2 weeks, then at 25 (relative to the first day of the last menstruation) the final stage of development of your baby is already beginning. But the immediate beginning of the 3rd trimester for mom remains the same - from 27 weeks.
Attention, childbirth
So we decided on when the pregnancy can be called almost completed. Only now is it worth understanding the features of this period of time. There are a lot of them, much more than at the very beginning of the path of bearing the fetus.
The third trimester of pregnancy from which week begins? As it turned out: with an obstetric period - from 27 weeks from the last month, and with an embryonic period - from about 25. There is nothing difficult about this. Orientation will be more in the first indicator, it is on it that both women and doctors are aligned.
The thing is that already at the beginning of the third trimester, your birth can begin! At about 28 weeks of gestation. This phenomenon is called spontaneous miscarriage or a similar birth process, premature. If the child develops normally, nothing bothers you, you should not panic very much. The baby will be born in a natural way, just until a certain moment he will stay in intensive care, connected to special devices that will help the newborn to come out, not yet fully formed. Quite a rare occurrence, but it does happen. Your doctor usually warns about the risk of premature birth.
Race
We have already figured out from what week the third trimester of pregnancy begins. Moreover, at the beginning of this period, one can encounter such a phenomenon as childbirth. But, as already noted, this does not happen so often. Therefore, it is worth considering a typical situation in which the expectant mother is equal to the DA.
A huge headache for women is the third trimester of pregnancy. Why? Already from 27-28 weeks and up to 30 inclusive (and this is about a month) you will be persecuted by doctors. Regular examinations and analyzes! One passed urine is not enough.
Many people remember the third trimester precisely by running around for doctors. First, you need to donate blood to many hormones. Not too critical, but sometimes unpleasant. Secondly, gynecological smears according to indications. Thirdly, the passage of narrow specialists. This moment is able to unsettle even the calmest pregnant woman. Very often it is narrow specialists (for example, a therapist) who start to raise excess panic around a woman in position, prescribe a lot of additional tests and studies, which is why the future woman in labor is not able to sign an exchange card in the hospital and conclude an agreement. But this is inevitable, have to be patient. When the tests are completed and the doctors are completed, you will finally be given recommendations on delivery.
By month
We have already figured out from what week of pregnancy the third trimester begins. Or from 27, or from 25. It all depends on what term you mean - obstetric or fetal. But now there’s another question that worries some quite seriously: “How many months is this?”
It is not difficult to guess (and count, too) that the third trimester begins with 7 months of pregnancy. And it lasts for 9 inclusive. Therefore, many people consider the periods of the “interesting situation” not in weeks, but in months. This is much easier than specifying obstetric and embryonic periods.
From now on, we know when the third trimester of pregnancy begins. Moreover, now it’s clear why you can mentally tune and prepare yourself, especially if you are not too fond of taking tests and going to doctors.
The final stage
What else can be said about the features that await the future mother in the specified period? For example, do not forget that normal births for the development of the fetus, but not entirely suitable for the mother and doctors, are possible. Also premature, but resuscitation is no longer required.
The thing is that it is important to know how long the third trimester of pregnancy begins, due to the likelihood of childbirth during this period. The question is when they will begin. Very premature and dangerous, equivalent to a miscarriage, occur at 28 weeks, but just premature babies are born at 36. This is normal.
Nevertheless, it is generally accepted by doctors that the body is completely ready for childbirth by the 38th obstetric week. And such births are normal. As practice shows, from 38 to 40 weeks they will certainly take place. Otherwise, you will have to wait for the expiration of the full fetal period. This is not the most common occurrence, but it does occur. Now it’s clear from which week of pregnancy the third trimester begins. Get ready for this period! Start collecting bags at the hospital!
