How is pregnancy not a personal circumstance? Anyway, you are right that they are not directly comparable because pregnancy and abortion are such unique things. I suppose the most similar analogy I could think of is a doctor refusing to perform a surgery which has a high chance of outright killing a patient and a smaller chance of treating the issue.
Either way, there is no constitutional right to an abortion, and that is the fundamental issue. Call your representatives and demand them to take action on codifying the right to abortion.
