Actually it does.
Fourth Amendment:
https://en.wikipedia.org/wiki/Fourth_Amendment_to_the_United_States_Constitution
In Roe v. Wade the Court considered that the body of a woman, i.e. her "person," was protected under the Fourth Amendment right to privacy via the due process clause of the 14th Amendment.
In order to prevent a woman from having an abortion, one must in effect "seize" her body by law to forbid the action from occurring. Otherwise she might take action (intentionally falling down stairs, trying to "dig it out" herself, taking "potions," or seeking an illegal abortionist) to abort herself. Then claim it was simply a miscarriage. All these things were being done, under pain of criminal law before Roe v. Wade, and they would continue had that decision not been rendered.
Women have a right to control their bodies. The issue is, when does the growing ZEF become legally (not morally or religiously) a human being worthy of the same Constitutional and legal protections as the mother?
Some argue at inception, others like myself when the fetus has enough traits to grant humanity coupled with viability.
