Your due date is wrong
- Your due-date is probably not your child's birthday.
That's because a mere 5% of babies are actually born on their estimated due date. A due date is just an estimation of when labor is most likely to start based on the average time it takes to conceive and carry a baby to term.
- The human body is far too unique for medical averages
The due date calculate is based on the average time of four distinctly unique events - namely, when you ovulated, conceived, the zygote implanted, and of course, your child's rate of growth in your more-unique-than-average body.
- Your true due date hides in the fog right up to labor
Estimating your individual due date based on multiple variable averages is like trying to select a due date on a tiny calendar with giant sausage fingers: it's going to be approximately in the right region, but could easily be off by up to a week or more.
