how can that happen, abortion isn’t in the constitution - either pro or con. a SCOTUS that tosses Roe, sure as hell isn’t going to invent some new right on the heels of that. Hell, they might as well just leave the one invented in 1973 in place if they are going to do that.
the “right to life” may well apply federally to ban 20+ week abortions, because viability can be demonstrated scientifically. but first trimester would return to the states. which states decide to ban it, and whether they can sustain that decision in their legislatures/governerships - its in their hands.
Scientifically and medically, the unborn child is a living human at every stage of development.
