Patient's question:
How is the duration of pregnancy calculated?Doctor's answer:
The duration of pregnancy is calculated from the first day of the last menstrual period, which is the standard in medical practice. If the menstrual cycle is irregular, the pregnancy duration needs to be estimated based on the results of early pregnancy tests, particularly the ultrasound findings. The accurate pregnancy duration is determined by ultrasound. A full term pregnancy is approximately 280 days. It is also recommended to undergo regular check-ups during pregnancy to monitor the normal development of the fetus.
