Pregnancy and date of birth:

Pregnancy is the condition of a woman for a period (~9 months) during which one or more children develop. Delivery usually occurs about 38 weeks after conception or about 40 weeks after the last menstrual period. The World Health Organization defines the normal duration of pregnancy as 37 to 47 weeks. At the patient’s first visit to the obstetrician-gynecologist, the doctor usually gives an estimated date (based on the ultrasound) or delivery date for the baby. The due date can also be calculated based on the last menstrual period.

Although gestational age can be predicted, the actual length of pregnancy depends on several factors, including B.’s age, the length of the previous pregnancy, and the mother’s birth weight1 . Studies have shown that less than 4 percent of births occur on the exact day of birth, 60 percent occur within a week of birth and about 90 percent occur within two weeks of birth. Even if someone can be sure that their child will be born within two weeks of birth, it is currently not possible to predict the exact date of birth.

Pregnancy detection (how to know)

Pregnancy can be detected by pregnancy tests or by the woman herself noticing a number of symptoms such as the absence of menstruation, increased basal body temperature, fatigue, nausea and increased urination frequency.

Pregnancy tests include the detection of hormones that act as biomarkers for pregnancy, as well as clinical blood or urine tests that can detect pregnancy six to eight days after conception. Although clinical blood tests are more accurate and can determine the exact amount of hCG hormone (which is only present during pregnancy) earlier and in smaller amounts, they are longer to assess and more expensive than urinalysis during pregnancy. A clinical urinalysis can also be performed, but it is not necessarily more accurate than a home pregnancy test and can be more expensive.
