Plan B and the moment of conception

I should put my own biases on the table here: Personally, I believe, for involved, more or less consequentialist reasons, that abortion should be legal, free of statutory encumbrances, and easy to get under all circumstances, up to the moment of birth. But I know that this isn't a popular position in America, even among people who generally support reproductive rights; I recognize that it is a difficult issue and I can sympathize with people who have moral qualms about late abortions.

Objections to abortion are sometimes phrased in terms of slippery slopes: if you support abortion under circumstance X then it's not a big stretch to support infanticide under circumstance Y, and where should we draw the line? (Most extravagantly, Philip K. Dick once wrote a misogynistic short story in which abortion had been extended to an option to kill your children up to the point where they learn algebra.)

In practice, though, nobody of consequence is advocating infanticide, and the true political slippery slope in the US slips the other way. Anti-abortion activists are turning their attention to bans and restrictions on various methods of contraception. This is logically perverse even from a hardline anti-abortion point of view, since a likely consequence of restricting contraception is to increase the rate of abortion, but it's happening.

So, does anyone in Massachusetts know what to do about voter registration if you move from one town to another (within Massachusetts) before an election, but after the deadline for registration to vote? Do you register for a residential address that is not yet your real address, do you vote in a ward and precinct that does not contain your real address, or do you just not get to vote in that situation?

(We've just realized that the gubernatorial primary is a few days after our planned move, and the registration deadline is Wednesday.)

Reading between the lines of FAQs and such, my guess is that you can only re-register after you've moved, and in this situation you vote at your old voting location. But nobody says this explicitly, and I want to be sure.

(Update: ckd has the answer—you can vote at your old location for up to six months or until an election for which you've registered at the new location.)
