In Roe v. Wade SCOTUS made abortion in the first 12 weeks of pregnancy a constitutional right; abortions after 12 weeks could be regulated by the states.
Overturning Roe v Wade by a new court would turn the US into a country where  changes to constitutional rights would be at the whim of whoever appoints new justices.   If it were overturned, then expect the next pro-choice president to start appointing justices that match the way  he/she thinks about abortion and not about the Constitution.

 The proper and correct way to overturn Roe v Wade would be by Constitutional Amendment.  It is hard to understand how conservatives who respect the Constitution could see it any other way.
