“although a brain has not developed yet, it is a FACT that the brain and competency is in the near future.”

That's why you get an abortion; to prevent it from developing further and becoming a person.

“There is a human life on the way when you are in the embryo stage”

It is already human life at the embryo stage, but that doesn't make it a person. "Human life" is not special.

Every time you sneeze you are ejecting human life, but it's not murder to kill a booger.

“and it is important to understand that that one person could affect so much.”

Yes, by getting an abortion you could be preventing a genocidal dictator from being born, which would make it very morally good to get an abortion. Good point.
