Planning a baby is a difficult process. The thing is that some couples cannot become parents for decades. In this case, any hint of a successful conception of a baby makes you nervous. Therefore, further we will try to figure out how to correctly determine the gestational age. By monthly? Ovulation? Delay critical days? Below is information about conception and the definition of the EDD. It's best not to experiment on your own and eventually see a doctor. Only a specialist will be able to accurately determine the stage of fetal development and the duration of the "interesting position". The suggestions below are not 100% accurate. They just help to guess the duration of pregnancy in one case or another.
Determination methods
Can I set the gestational age by menstruation or not? And if so, how to do it?
To datewomen can define "interesting position" in a variety of ways. Among them, the following techniques are distinguished:
- by last period (or late);
- on ovulation;
- by date of conception;
- on ultrasound.
You can cope with the task with the help of pregnancy tests. Electronic devices for home diagnostics of "interesting position" often have indicators of the duration of fetal development.
About conception
It is possible to calculate the gestational age by menstruation, but this technique is not distinguished by its accuracy. The thing is that the female body is a huge mystery of mankind. Some processes familiar to a girl are influenced by external factors. Because of this, some changes in the body as a whole are not ruled out.
For example, external factors accelerate or delay ovulation. This is an extremely important process for conception. Usually it is during this period that the chances of getting pregnant are maximum.
The process of conception usually happens like this - first, the egg matures in the body, then at ovulation it breaks out of the follicle and begins to move towards the uterine cavity. If during this period of time the egg collides with active sperm, conception occurs. The fertilized egg is attached to the uterus. This is how pregnancy occurs.
If the spermatozoa did not meet the egg, then, having reached the uterus, the female cell will die. She will retain her reproductive properties only 2-3 days after ovulation. After that, the body willprepare for the start of a new cycle.
Important: Ovulation lasts about 48 hours. This means that the chances of getting pregnant in general are extremely small. Especially if a woman and a man do not plan to become parents.
When do you ovulate?
Calculating the gestational age from the last menstruation and determining the expected date of birth is not so difficult. But first, a woman needs to know when she ovulates.
Usually this period falls in the middle of the menstrual cycle. On average - 14-15 days after the start of the next critical days.
To help determine the right period for conceiving a baby, ovulation tests or ultrasound of the pelvic organs will help. This way you will be able to "catch" ovulation with maximum accuracy.
According to ovulation
Pregnancy period by monthly calculation is calculated without much hassle. The main thing is to know how to act.
You can determine the estimated date of birth by ovulation. To do this, you need to find out the day of ovulation and add 280 days to it. Only this technique has nothing to do with the gestational age.
Usually, the "interesting position" for ovulation is calculated a little differently - you just need to calculate how many days have passed since the "day X". This is the duration of the development of the fetus. It is called fetal gestation.
Delay of critical days
Need to calculate the gestational age by monthly? It's not that hard to do it week by week. It is enough to be guided by the simplest rules.
It's all aboutthat ovulation usually occurs in the middle of the menstrual cycle. As mentioned above, on the day of delay of critical days, the term of embryonic pregnancy can be calculated in weeks and days.
There is also the concept of obstetric term "interesting position". It is determined by the last menstruation. What does this mean?
The duration of pregnancy by menstruation is determined as follows - you need to remember when menstrual bleeding began for the last time. The time elapsed until the date of the calculation is the obstetric period. It is usually 2 weeks longer than the embryonic one.
DA for last period
The due date is what every expectant mother wants to know. This information will help you prepare for your new addition to your family.
We were able to calculate the gestational age by the date of the last menstruation. And what to do to install the PDR?
You can subtract 3 months from the date of the last menstruation, and then add a week to the resulting "figure". This is how childbirth is calculated taking into account the obstetric term of the "interesting situation".
Ultrasound and checkup
Now it is clear how you can calculate the gestational age from the last menstruation. And how the date of birth is calculated is also clear. Now consider other methods for determining the "interesting position".
Some are sure that by ultrasound, doctors will be able to easily understand when conception occurred. Unfortunately, this is not entirely true. Yes, ultrasound diagnostics helps to clarify, but it is better not to take the received data as an axiom.
Usually on ultrasound already at 4-5a week, a fetal egg is clearly visible, at 5-7 weeks, a heartbeat is heard in the embryo. These data will help to predict pregnancy and the stage of development of the fetus.
Important: during a visit to the ultrasound room, it is worth remembering when a woman had her last menstruation and unprotected intercourse. This will help the specialist in confirming the diagnosis and establishing the EDD.
Tests to help
Does the girl miss her period? The gestation period at this point is usually about 1 month. This is the obstetric "period". The embryonic gestation period by the time of delay of critical days reaches 2 weeks. This discrepancy often confuses girls.
As we have already said, if desired, a woman can buy an electronic pregnancy test. Such a device helps not only to determine the "interesting position" with maximum accuracy, but also indicates the obstetric gestational age.
What to do? You just need to substitute the test receiver under the stream of morning urine (or apply some biomaterial to the receiving area), and then look at the information window. The diagnostic result will be displayed here. On some tests, there will be an inscription next to it with the term "interesting situation".
Important: even this trick cannot be considered reliable. It helps to draw conclusions about pregnancy by the level of hCG in the blood. It can be produced in greater or lesser amounts during the pathology of pregnancy.
Online calendar
You can calculate the gestational age by the last menstruation if you find out how much time has passed before the delaymenses. This is an "obstetric pregnancy".
Today, you can find a variety of online calculators on the net. With their help, a woman is able to calculate the pregnancy and determine the estimated date of birth.
What to do to achieve the goal? A woman will have to:
- Find a special "pregnancy calendar". Such services are usually found on women's forums.
- Indicate the date of the last menstruation.
- Set the day of the inspection.
- Enter the estimated date of conception. Some calculators can print the day you had unprotected sex and the length of your menstrual cycle.
- Press the "Calculate" button.
The requested data will appear on the screen. Namely - the gestational age and the expected date of birth. You can consult a doctor to clarify the situation.
Signs of pregnancy
Everyone can now calculate the gestational age by the last menstruation. A woman who carefully monitors her body will not be able to do this. The main thing is to determine ovulation and find out exactly the day of delay of critical days.
Some girls are interested in the first signs of successful conception. Unfortunately, they are easily confused with PMS.
Here are the main signs of pregnancy in early missed periods:
- absence of menstrual bleeding;
- mood swings;
- nausea and gagging;
- general weaknessorganism;
- pain in the lower abdomen and pelvic region.
Sometimes girls experience implantation bleeding. These are smears of blood released when the fetal egg attaches to the uterus. They are easily confused with the onset of menstruation.
As practice shows, the very first (and most often obvious) sign of pregnancy is a delay in menstruation. To determine the beginning of new critical days, it is recommended to use special calendars.
Negative test and delay
We figured out how to calculate the gestational age by the date of menstruation. But what if a woman had a missed period, but the test shows one line?
The problem is that late critical days can be caused by various factors. For example:
- delayed ovulation;
- gynecological diseases;
- anovulation;
- stress;
- presence of tumors;
- taking hormonal drugs.
If the test shows one strip with a delay in menstruation, it is recommended not to rush to conclusions. Home diagnosis of "interesting position" is not accurate.
What is a woman to do? You need to repeat the test in a few days. After that, it is recommended:
- do an ultrasound;
- donate blood for hCG;
- go to the gynecologist.
All this will help determine the duration of pregnancy. For menstruation and their delay, gynecologists often set PDR. MoreIn addition, they have special calendars to help you quickly set the "interesting position" date.
Conclusion
Now it is clear how a girl can calculate the stage of fetal development. We also talked about ways to diagnose pregnancy in the early stages.
All of the above tips really help when planning a baby. Moreover, a woman is advised to combine all the above tips to clarify the DA.
It is important to remember that pregnancy and childbirth are processes that can be provoked absolutely unexpectedly. And even the PDR is not the exact date of replenishment in the family. These are guidelines to help women and doctors prepare for childbirth.
If a woman keeps a basal temperature chart, she can see conception on it. Usually in this case, the body temperature is set at a value above 37.2 degrees for several days longer than usual.
As a rule, the gestational age for menstruation is calculated without much difficulty. The simplest mathematical skills will help bring the idea to life.
