Every woman is different; every pregnancy is different.
Yes, your due date could be affected, but I wouldn't worry about it. Most doctors are induction-happy anyway, so babies are often born (artificially) too early, and then have problems adjusting. Not every apple on the tree ripens at exactly the same time; some go faster and others slower.
A "due date" is an estimation, and [as Laura Ingalls Wilder said about ambition] is "a good servant, but a bad master." It may give you a statistical norm, or a date that may be a good thing to keep in mind so that you'll know if your baby is way early or way late, but it is *just* an ESTIMATED due date, and is most certainly not set in stone!
There have been babies born "early" (according to their due dates) who were actually term; and there have been, sadly, many more babies born on or near their due dates who were actually preterm and had problems adjusting to life on the outside (spent time in the NICU, had breathing problems, etc.) because they were actually premature.
Think, "By Thanksgiving my baby will be here," and then if it's late, you won't be so anxious. But you can work on having everything prepared by early October so if your baby is born a few weeks before your Halloween "guess date", then you'll still be ready. And, really, that's what all women have to do anyway. "Term" is from 37-42 weeks of gestation, so we *all* have a 5-week "window" of when birth may happen.
P.s., Go with the later date - it will save you the hassle of being induced too soon for going "too far past your due date" if you don't have the baby by Nov. 7. And if you have the baby 3 weeks before that date, then it's still term.
