Question

Quizplus · Accepted Answer

The due date is typically calculated from the first day of the last menstrual period. This is because it is easier to track and predict the date of the next menstrual period than ovulation or conception. The due date is typically estimated to be 280 days (or 40 weeks) from the first day of the last menstrual period. However, this may vary depending on individual factors and may not be completely accurate.
