Patient's question:
How is the duration of pregnancy calculated?Doctor's answer:
The gestation period 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 early pregnancy test results, particularly the results of a color Doppler ultrasound. The accurate gestation period is determined by ultrasound. A full term pregnancy is approximately 280 days. It is also recommended to undergo regular prenatal check-ups during pregnancy to monitor the normal development of the fetus.
