Prove that. I, and others can certainly prove that we are human beings from the time we are concieved. I would be interested in seeing you prove your assertions. If you could go into the chambers of the supreme court justices, or practically any other judge in this country, you would find a legal dictionary. Specifically, Black's Legal Dictionary as it is THE legal dictionary. When a dispute arises over the meaning of a legal term (person is a legal term) the judge settles the dispute by reading the definition of the argued legal term.
Go to your local library, to the reference section, take a copy of Black's Legal Dictionary and turn to page 1152 (depending on the edition). Look at the word "person". You will see that the legal definiton of the word person is "a human being". No more, no less. A human being. Nothing at all about feelings or other things. Simply a human being. That is why the court found that it must deny that unborns are human beings at all because to admit that they were human beings was to admit that they were in fact, persons.
It is possible to formulate a birth control pill that prevents ovulation but does not have abortificant effects. By the way, there is no such thing as a fertilized egg. Upon conception, a human being exists, not a fertilized egg.
"Often,this morula is inaccurately referred to as a ‘fertilized egg’ because the blastomeres remain inside the female parent’s oocyte outer cell membrane. That is an incorrect characterization, because the 23 -chromosome oocyte no longer exists; all the cells within the morula have the unique genome—46 chromosomes and a complement of mitochondrial DNA —of the newly conceived individual life." Moore and Persaud, The Developing Human, 6th ed., (p. 43)
I doubt that most Germans saw what happened to the Jews as murder and it is almost a sure bet that most people in early US history didn't see killing a slave as murder. One can only rightly view killing a human being as murder if one recognizes the one being killed as a human being. If most people don't see abortion as murder, then you are saying that most people are so ignorant of the subject of human developmental biology that they don't recognize when an individual human being comes into existence.
You don't become a human being by virtue of your stage of development. If your argument were true, then a mother could rightly kill her 3 year old because the child won't be a "fully developed" human being until sometime in her late 20's.
As to sharing "bodily resources" I suggest that you do a bit of research into conjoined twins. Very often, they share a vital organ. They may not be separated unless the organ is so weak that both will die if the separation is not attempted no matter how inconvenienced the twin with the organ may feel. Thus, there is ample legal precedent for requiring one individual to share bodily resources with another.
