Your approximate due date is that day within the next year.Take note of the word âapproximate:â Your baby will grow and mature on his own schedule. The only thing youâll know for sure is that you should give birth within two weeks before or after that day.emember: Your due date is an estimate of when you will give birth, not a guarantee. If you are âover due,â just count it as more time to establish a bond with your baby, to prepare mentally for motherhood, to discuss your partnerâs role during the birth and to ready your home for your babyâs arrival.
