The DNA would disagree.  The "fetus" as the term you insist upon using is simply an unborn human. 

It interests me how some are so protective of unborn  animals and birds, protecting their habitat and passing laws making it illegal to harm them - but NOT unborn humans.

I have never heard a woman joyously proclaim, when happy with a positive pregnancy test, "I'm having a fetus!!"

It's a baby.  An unborn human being, with all the DNA and genetic markers of a human.  Time to admit that. Just because some have been either brainwashed or duped into thinking otherwise with the use of sanitized and dehumanizing terminology does not make it so.
