What is the gestational age for weeks and days? First of all, the girl or her gynecologist should find out when the direct conception occurred. Without this information, it is problematic to specify the stage of development of the fetus. Fortunately, you can cope with the task in different ways. And each woman can decide for herself exactly how to make her calculations. Next, we will try to consider all existing options for the development of events.
Types of Dates
Every girl can calculate the gestational age by weeks and days. The main thing is to know how to act in a particular case.
But first, you have to remember one simple truth - the duration of pregnancy can be different. It is conditionally divided into two types. Which ones?
You can find out information about the obstetric period of pregnancy, or you can find out about embryonic. These periods are slightly different from each other. And therefore, sometimes unprepared women have some problems. All of them are solvable. And then we will try to understand how not to get confused in the periods indicated earlier.
About obstetric
What is the obstetric gestation period of weeks and even days? First of all, you need to understand what it is all about.
Obstetric is considered the gestational age, counted from the first day of the last menstruation. It helps to establish the DA, and also to understand exactly when the conception could occur.
About embryonic
You can also hear from a doctor or a specialist in an ultrasound room about the fetal period. What is it?
This is the term for direct development of the fetus. He is two weeks less than obstetric. Serves as a loyal assistant in determining pathologies of the development of the future baby.
Counting Methods
Calculating the gestational age in weeks or days is not as difficult as it seems. The main thing is to choose for yourself a particular methodology for obtaining the information necessary for a woman.
At the moment, you can find out about pregnancy and suggest its term:
- blood test;
- using ultrasound research;
- through the gynecological calendar;
- calendar method of counting;
- with the help of fetal movements;
- online calculator;
- according to the DA, if it is delivered;
- according to the basal temperature graph.
You can also purchase a special electronic pregnancy test at the pharmacy. Some of these devices show not only a successful conception, but also the term thereof. True, the test will have to be spent.
The exact gestational age for weeks to determine is usually problematic without the help of medical specialists. All of these methods, with the exception of passing tests, a visit to the gynecologist, as well as in the office of an ultrasound study, cannot be considered reliable. But all together they provide the most accurate data.
Important: when determining the stage of development of pregnancy, it is recommended to focus on the obstetric period.
Last monthly
What is the correct gestational age in weeks? It all depends on what kind of data the girl wants to receive. Let's start by calculating the obstetric gestational age. He, as already mentioned, helps to predict the date of birth, which is an extremely important point.
Usually, girls consider the gestational age from the last menstruation. You need to remember when was the last menstruation, and then think about when it started. The time interval between the start date of the calculations and the start of the critical days is the gestational age. It can be considered in days, weeks, and even months - as it suits anyone.
By blood
Interested in gestational age? How many weeks should I wait before visiting a doctor or before using a special pregnancy test?
In general, there is no need to rush to check for the success of conception - everything has its time. Early diagnosis may be false, for some reason.
The thing is that immediately after the conception of the baby in the body of a woman, certain changes begin to occur. A "pregnancy hormone" is produced in the blood. It is called hCG. It is to him that pregnancy tests respond. One changes depending on the term of an interesting situation.
The table above will help to predict the gestational age according to the results of a blood test for hCG. It is better to wait for the delay of menstruation before passing it. Otherwise, the girl may miss the pregnancy in the early stages.
BT calendar
How many weeks is considered early gestation? Usually this is how the first trimester of an interesting situation is described, up to 12 weeks (obstetric). Up to this point, each pregnant woman may, of her own free will, have an abortion or register with the Housing Authority in order to receive appropriate benefits in the future.
In any case, you first need to understand that conception has been successful. This is not always easy to do, but if a woman is attentive to her body, you can try to get the necessary data as soon as possible. A graph of basal temperature helps to judge the successful conception of the baby. True, it will have to be conducted in advance and for several months.
Typically, with ovulation, BT rises to 37-37.7 degrees, stays at these values for several days, and then, if conception has not occurred, drops to normal. In case of pregnancy, the temperature remains elevated in the early stages. So, the deviation of the BT schedule from the norm is a clear sign of a successful conception.
Now what? You need to look at the graph of basal temperature and determine the date of conception of the baby. After that, it remains only to calculate the difference between the day of pregnancy and the time when the girl decided to carry out the appropriate calculations.
Stirring
How is a gestational week? The main problem sometimes becomes determining the date of conception of the child. And therefore, it is necessary to carry out the corresponding calculations by various methods.
Some girls may realize that they are pregnant by the movements of the fetus. True, they don’t usually wait so long. The thing is that the girl can feel the first movements of the future baby in the second trimester - at the 16-20th week. Accordingly, it can be quite easily understood from them when the pregnancy came, conception occurred, and also put the PDR.
Internet calculator
The gestational age for weeks and days for each woman can be found without leaving home. True, this technique is somewhat reminiscent of a calendar method for determining the obstetric gestational age. It is about using special online calculators on a variety of women's sites and forums.
Usually, in order to use this technique, it is recommended to proceed as follows:
- Remember when was the last menstruation. More precisely, when did it begin?
- Find and open the so-called pregnancy calculator on the Internet.
- Write how much on average there will be a difference in days between critical days, as well as the date of the last critical days.
- Click on the button responsible for the start of calculations.
All that remains now is to carefully look at the screen. It displays information about the DA, as well as the current gestational age in weeks and days. Very comfortably! There is no need to use the calendar method and independently calculate the relevant data.
If PDD is known
How is a gestational week? The answer to this kind of question is already known. But the previously listed tricks are not exhaustive. You can achieve the desired result in different ways. True, it is better to give preference to medical methods for diagnosing pregnancy and setting PDR.
It happens that the doctor reports the estimated date of birth, and the woman forgets the rest of the information. If you can’t see it in the exchange card or help, you can find out yourself when an interesting situation has come.
To do this, 9 months must be subtracted from the estimated date of birth. The time obtained is the beginning of the obstetric gestation period. Accordingly, with the help of this one can understand at what stage the development of an interesting situation is a girl. There is nothing difficult in this - only the simplest mathematical operations.
About tests
Calculating the gestational age by weeks and days, as already noted, is not as difficult as it seems initially. In any case, if a woman is responsible for her body and knows its features well.
It was previously emphasized that with the help of a special pregnancy test, a girl can find out about the gestational age. To achieve this goal, you just need to buy an electronic pregnancy test in a pharmacy, for example, Clearblue. It shows the presence of a successful conception, and the period of an interesting position in weeks.
Suppose a test is purchased. Now what? Typically, you must do the following:
- Wait until there is a delay in menstruation. Up to this point, the test (even electronic) may be wrong.
- Take a pregnancy test in the morning and urinate on it.
- Lay the device on a dry vertical surface (preferably).
- Look at the result.
Such a diagnosis is available to every girl, it takes only a few minutes. True, pregnancy tests can be wrong. And therefore, as already mentioned, it is better to contact specialist doctors if you suspect a successful conception. Only they are able to most accurately set the gestational age, as well as determine the pathology of the fetus, while also setting the estimated date of birth.
By ultrasound
Medical diagnostics of an interesting position is the most accurate. If a girl wants to quickly understand that she is pregnant, you need to give preference to more accurate methods of solving the problem. There are not so many of them.
You can go and do an ultrasound. According to the gestational age (in weeks), the PDD, the embryonic period, and even the pathology of pregnancy are determined. Can the date of birth be guessed this way? Quite.
A specialist doctor will do an ultrasound of the pelvic organs, and then report the presence or absence of a successful conception. In the first case, they can also suggest or accurately name the gestational age. At the 6-8th week, the fetal heartbeat begins to be heard and visible.
Important: if you arrive at the ultrasound too early, some medical specialists may confuse the ovum with the inflammatory process or cyst. Such cases do occur in practice, although not too often.
It is recommended to visit the ultrasound room to determine pregnancy only after the critical days have not arrived on time. Until this happens, the probability of error will be quite high.
At the gynecologist
What is considered the gestational age by weeks, we found out. You can always clarify information about the fetus, as well as about the development of pregnancy, at the gynecologist. This specialist collects an anamnesis, and then provides the patient with information of interest to her.
As a rule, at the first visit to the gynecologist due to pregnancy, the doctor asks:
- when was the last unprotected intercourse;
- how long menstruation lasts;
- when were the last menstruation;
- is there a delay of critical days.
Using this information on a special gynecological calendar, the doctor marks the beginning of pregnancy, and then determines its current term, puts the PDR.
Also, a woman will have to undergo an examination on a gynecological chair. The gynecologist will be able to determine whether the pregnancy is by the state of the girl’s internal organs. For example, on the cervix - it acquires a bluish tint.
With IVF and the normal cycle
Interested in gestational age? How many weeks a girl is pregnant, it is not so difficult to find out. The main thing is to act consistently, as well as determine the appropriate diagnostic method.
Increasingly, couples perform IVF. In this case, the definition of the day the pregnancy begins has its own characteristics. Women with a normal cycle, as a rule, can focus on the day when the last critical days began. The obstetric period will be counted from the corresponding day.
IVF and long cycle
The situation with IVF is somewhat different if a woman has a long menstrual cycle. In this case, the obstetric period will differ from the fetal period by about a month. This difference is unacceptable, it leads to serious problems in determining the DA, as well as the current gestational age and fetal pathologies.
What to do if a woman has IVF, and she also has a long menstrual cycle? In this situation, as a rule, it is necessary to consider the development of gestation from the moment of embryo replanting. And the beginning of the last critical days of gynecologists in this case is not particularly interested. In any case, such information to calculate the time of pregnancy will be superfluous.
Conclusion
We figured out how to calculate the gestational age in weeks, as well as days and months. To cope with this task is offered in different ways. It is better to use several techniques for obtaining data of interest at once, as well as consult a specialist doctor.
Some girls say that they understand that they are pregnant, right after conception. Nobody has canceled internal intuition, but you should not rely on it. And trust the harbingers of successful conception like toxicosis and implantation bleeding, too. Similar symptoms may indicate hormonal failure. Does a woman have a week of delay? The gestational age in this case is usually about 4 weeks. This is an obstetric term. As soon as there is a delay in menstruation, you need to do a test and go to the doctor.
