In the US humans have rights on a sliding scale, a child does not have the same rights as an 18 year old
I don't think its unreasonable that a fetus, being a clump of cells that cannot survive and is not independently living, has less rights to life than a minor child
The mother is the fully independently living human in this case with full rights, those should not be overridden by a clump of cells with potential
If we judge everything by it's "potential" then we need to start charging men for masturbating and not saving their ejaculate and charging women for having menstrual cycles
