Doctor's answer:
Hello, the duration of pregnancy is generally calculated from the first day of the last menstrual period. Usually, in early pregnancy, a gestational sac can be seen around 35 days via ultrasound, while for some, it may take around 40 days to see it. Therefore, at 20 days of pregnancy, it is not visible on ultrasound.If the menstrual cycle is regular, a color Doppler ultrasound around 40 days after the period is recommended. At 20 days, it is too early, and the gestational sac may not have reached the uterine cavity yet, making it undetectable. Generally, a conventional ultrasound can detect pregnancy as early as 35 days, but for some individuals, it may take around 40 days to see it.
