Frequently Asked Questions
ETG stands for Estimated Time of Gestation, which is the estimated length of pregnancy from the last menstrual period or conception.
Due date is calculated by adding 280 days (40 weeks) to the first day of the last menstrual period, adjusted for cycle length, or adding 266 days to the conception date.
Cycle length affects ovulation timing. A longer cycle shifts the due date later, while a shorter cycle shifts it earlier.
