Even if that happens, then it goes back to the states, right? I think the left is pretty well organized on this, so I suspect you'll see them offering financial assistance, housing, transportation to an abortion friendly state (for example, my pathetic state Taxifornia, aka the Peoples' Republik of Taxifornia) to those who want an abortion. So even if it's overturned, the number of lives saved will not be as great as those against abortion would like.
