“Exact due dates are an imperfect science because they take into account the first two weeks of your cycle (when you are menstruating and preparing to release an egg, i.e., not yet pregnant) as part of the pregnancy. This means that by the time you become pregnant, you're already 'late' according to the 40-week pregnancy timeline. Studies show that first-time mothers often go 7-10 days past their estimated due date (EDD). I highly encourage women to diligently track their cycles if planning to conceive and to advocate for adjusting their due dates if necessary."
