Nope, that exists nowhere in the Constitution . . . purely in the addled fantasies of Harry Blackmun back in 1973.
The Constitution is what the Supreme Court says it is, because every organ of American government, and the American people themselves, make it so by obeying every act of the Supreme Court.
The actual Constitution itself is a vague muddle that doesn't spell out much in detail, other than a few procedures. Powers are broad, undefined, and "understood" within the context of their times, then and now. It's very much a "Common Law" Constitution.
And anyway, if being "in the Constitution" is the issue, there's no right to life in there. There is merely the right to not be deprived of life without due process of law. Due process of law is not defined anywhere in the Constitution, and was assumed to be (and is) defined by whatever the Courts, Congress and the Executive between them say due process of law is.
Sola Scriptura doesn't work all that well with the Bible, and it collapses totally when one tries to apply it to the US Constitution!
