Pregnancy Calculation

Thanks to the pregnancy calculation, it is possible to determine the estimated date of birth. In addition, thanks to the pregnancy follow-up, the development and health status of the baby in the mother's womb can be evaluated. During pregnancy, screening tests are performed for expectant mothers at certain times. It is important to have these tests done in the appropriate week. Detection of genetic diseases and a developmental delay in the baby in the womb can be determined by these screening tests. Therefore, weekly follow-up of pregnancy can be done more healthily with pregnancy calculation.

Pregnancy follow-up is necessary in order for the baby to develop in a healthy way in the mother's womb and for the birth to take place in a healthy way. Therefore, pregnancy calculation becomes important. A planned pregnancy helps the expectant mother to be conscious. However, it is seen that there are fewer planned pregnancies today. In this respect, the calculation of the estimated date of birth and pregnancy calculation come to the fore in terms of monitoring the pregnancy. Pregnancy calculation is made as an estimate. The main reason for this is that many factors can affect the date of birth during pregnancy.

Determining the estimated date of birth with pregnancy calculation

Normally, the gestation period covers an average of 40 weeks from the fertilization of the egg with sperm. This includes a 40-week period from the woman's last menstrual bleeding. The calculation of the estimated date of delivery after the onset of pregnancy is evaluated according to the 40 weeks of pregnancy. But deliveries can occur at 37 and 40 weeks before 40 weeks of pregnancy. In some pregnancies, premature birth may also occur due to possible risks. In some pregnancies, delivery may occur at 41-42 weeks.

The onset of pregnancy, as a rule, is considered to begin with the fertilization of a woman's egg by a man's sperm. However, during pregnancy calculation, the day of intercourse is not evaluated as such. According to the standard brought in this calculation, it is accepted that pregnancy begins on the first day of the last menstrual bleeding seen by the expectant mother. During pregnancy calculation, the month is not used at the same time. Pregnancy is considered to normally last 280 days in humans. This period corresponds to a total of 40 weeks. Therefore, the first day of the woman's last menstrual bleeding is taken into account when calculating the estimated date of delivery. Since this date is considered as an estimate, it gives information about the estimated time of delivery for the mother and doctor.

If the birth does not occur on the date determined by the pregnancy calculation

When calculating the estimated date of birth, the 40-week gestation period is determined based on the first day of the woman's last menstrual period. Normally, not much change is expected in the calculation made in this way. However, if necessary, the corrected date of birth of the woman can be calculated with the help of the measurements in the ultrasound examinations made by the doctor.

Ultrasound measurements made by the doctor in the first months of pregnancy are made with pictures or papers. These data should be protected by expectant mothers. This data can be used if there is a disruption in the date of birth. If the birth does not occur within 40 weeks, which is determined by ultrasound detections and the last menstrual period data of the woman, some tests can also be performed. In this way, it can be expected up to 41-42 weeks of pregnancy. After this period, birth can be performed by external intervention.

How to calculate pregnancy?

The Nagele method is used to calculate the estimated date of birth during pregnancy. During pregnancy calculation made with this method, seven days are added to the first day of the last menstrual bleeding. The estimated date of birth of the pregnant woman is found by going back three months from the date found. Thanks to the calculation, the gestational week of the woman and the estimated date of birth are determined. This calculation gives the due date when the birth will occur. Usually births take place before this date. Therefore, women should be sensitive about the last menstrual period in planned and unplanned pregnancies. This is important in terms of pregnancy follow-up and the healthy development of the baby.

Pregnancy calculation and ultrasound measurements of the baby

The first day of the last menstrual period of the expectant mother is an important data for pregnancy calculation. However, in some cases, this may not be sufficient in calculating pregnancy. Therefore, ultrasound measurements of the baby made by the doctor at the beginning of pregnancy should be carefully stored. With ultrasound measurements, it can be determined in which week the pregnancy is and whether the baby is healthy or not. In addition, when the birth does not occur on the estimated date of birth, as expected, ultrasound measurements in the first months are very useful. In this way, the corrected date of birth of the woman can be determined and the birth can be carried out in a healthy way. When the birth does not occur on this date, cesarean delivery may be preferred.
