Here is a quotation from an excellent article regarding the unconstitutional nature of Roe v. Wade.  The entire article is well worth a few minutes.

“From a constitutional perspective, moral arguments are irrelevant.  Properly understood, the abortion question is a matter of federalism.  Our Constitution lays out a governmental framework that is really quite simple.  The powers of the national government are enumerated in Article 1, Sec. 8.  The Tenth Amendment then tells us that any power not enumerated as a federal power (or prohibited by the Bill of Rights) is reserved for the states.  This includes a wide range of state regulatory powers (known as “police powers”) which include authority over many moral and social issues.  For example, the Constitution does not mention prostitution; therefore, it is a question for the states to decide according to their own local morals.  The state of Nevada has chosen to legalize prostitution; forty-nine other states have chosen to outlaw it.

The same logic should be applicable to abortion — and it was, prior to Roe.  By 1973, four states had legalized abortion, and forty-six others had restricted it.  But the Supreme Court decided that it was going to ram abortion down the nation’s throat, whether it had constitutional justification to do so or not.  The end result was a train wreck of an opinion.  Conservatives who oppose Roe ought not speak about it in hushed moral tones, but rather with derisive hoots, jeers, and catcalls.  The decision is intellectually fraudulent, and anyone who takes it seriously reveals his own intellectual insolvency.”
