Even without these points (heart beat, sentience, etc.) I think the main reason for avoiding abortion is that the embryo/fetus is living and will turn into a full grown baby, then on to a young child, adolescent...etc.
No, it won't necessarily do that. It could also result in a spontaneous abortion.

Having an abortion at any stage is like pouring the cement for the base of a house, maybe getting the frame built and some wiring then demolishing it.
Which is a completely sensible thing to do if you change your mind.
Your analogy sucks though. A better one would be that your hobby is to weld random pieces of metal together and suddenly realizing that you have made the base for an airplane, which you then disassemble because that's not what you wanted to do.
