Introduction
The normal delivery time for a first pregnancy typically falls between 37 and 42 weeks. Generally, a pregnant woman's due date is calculated from the first day of her last menstrual period. According to this method, pregnancy usually lasts about 40 weeks, or 280 days. However, this calculation is not very accurate because it assumes that every woman has a 28-day menstrual cycle.
The normal delivery time for a first pregnancy typically falls between 37 and 42 weeks. A detailed explanation is as follows:
Under normal circumstances, a pregnant woman's due date is calculated based on the first day of her last menstrual period. According to this method, the gestational period usually lasts about 40 weeks, or 280 days. However, this calculation is not entirely precise, as it assumes that every woman has a 28-day menstrual cycle and that ovulation and conception occur around the 14th day of the cycle. In reality, many women have varying cycle lengths, which can affect the accuracy of predicting the end of the pregnancy. Furthermore, studies have shown that the gestational period for first-time mothers may be slightly longer.
It should be noted that even if a pregnancy extends beyond 42 weeks, it does not necessarily indicate a problem. In such cases, doctors will conduct thorough examinations and assessments to ensure the fetus is healthy and determine whether labor induction or other medical interventions are necessary.
