No **** it wasn't it takes 2/3rds of the States voting for a Constitutional Convention or 2/3rds of Congress voting for an amendment. None of these where done. Abortion has never been a Constitutional right. The education system has gone to shit in this country.
Why are you talking about amendments?
I tried to steer you in the right direction hoping you would do some research before continuing to expose your ignorance but evidently I need to help you out a bit more.
The constitution is important. Please read carefully.
Abortion was a constitutional right based on the 9th amendment. Just like presumption of innocence and the right to travel are not "enumerated" in the constitution yet are constitutional rights nonetheless and subsequently are what is known as "unenumerated" rights.
James Madison championed the 9th amendment and ultimately was likely the reason it was agreed upon to submit a bill of rights.
Before this, many founders knew they could not list every possible right and we're concerned because a right wasn't specifically listed in the constitution then it would be subject to govenrment control. Their concerns were well founded based on your arguement alone.
James Madison put it way better then I can though so here are James Madison's thoughts on the bill of rights and how the 9th amendment could be used to assuage their fear of to much government power.
"It has been objected also against a bill of rights, that, by enumerating particular exceptions to the grant of power, it would disparage those rights which were not placed in that enumeration, and it might follow by implication, that those rights which were not singled out, were intended to be assigned into the hands of the general government, and were consequently insecure. This is one of the most plausible arguments I have ever heard urged against the admission of a bill of rights into this system; but, I conceive, that may be guarded against."

Thus the 9th amendment was born.
I hope this helps you better understand how our constitution works. I highly recommend reading the entire link I provided. It is relatively succinct and should clear any questions you may have.
Good luck and have a great weekend!
