Every pregnant girl, woman from the beginning of conception is interested in the date of birth of her future baby. It is necessary to be able to calculate the gestational age by weeks for many reasons.
After all, this will determine the dates of maternity leave, the onset of childbirth, the delivery of tests, as well as the possibility of planning the purchases necessary for the appearance of the child. Women are interested in the process of changes that occur in their bodies during pregnancy, and the development of the baby by week. You can calculate
the gestational age by weeks on your own or with the help of specialists and consultants at the clinic where the
expectant mother will be observed. First of all, to calculate the gestational age, you need to know the date of the last menstrual cycle. Two weeks are added to this day (this is an approximate
day of conception), and then forty weeks are added to the received date (in some cases, the date varies from thirty-eight to forty-two weeks).
Experts advise to have your own pregnancy calendar for weeks, where the exact dates of ultrasound, a doctor’s examination, baby’s development, the onset of stirring and other changes in the woman’s body will be kept. Doctors also have their own patient monitoring journal (most often it is on
the pregnant woman’s
exchange card), which takes into account changes in the volume and weight of both herself and the unborn baby. You can also calculate the gestational age by weeks using a special calculator that works according to the Negele formula, where three months are subtracted from the first days of the estimated menstrual cycle, and then seven days are added. The received date will be the day of the onset of childbirth.
Experienced doctors determine the exact date during a gynecological examination or an ultrasound examination, and in the second trimester - by the date of the first stirring and the length of the uterus, which begins to change in size already in the twelfth week (increases by about one centimeter every week).
An accurate weekly calculation will help the doctor to determine in advance unwanted deviations from the norm of pregnancy and at the same time allow the doctor to carry out the studies on time. Pregnancy and childbirth are always psychological, physical and emotional changes in a woman's life. Now she should know how to eat properly, what to do, take care of herself, and do breathing exercises. In weekly steps, tracking is much easier.
In most cases, when pregnancy occurs, the date of birth, established by specialists, can fluctuate around one to two weeks. Therefore, the calculation results should be used in combination. Only high-level specialists will help you calculate the gestational age by weeks and do all the above actions. You should not save money on this, because the health of your children depends on it.
Proper pregnancy management and a clear definition of the date of birth will help you avoid most of the various unpleasant situations that may arise during the development of the fetus.
