Determining the due dates for most pregnant women is fun. But 80% of pregnant women look forward to this date by frequently asking their health care provider their EDD known as Expected Due Date. So, the methods used by medical practitioners can as well be used by pregnant women just to double check when their baby will come to life. Dr. Naegele, circa 1850, determined that the average length of human gestation was approximately 266 days from conception. He assumed that the average woman had cycles that lasted 28 days and that she ovulated on Day 14 of her cycle. He used his data to come up with a mathematical calculation for due dates.
In the next page, we shall discuss about some factors and assumptions to consider in the determination of due dates.
