Apple tastes weird

Nothing is wrong with this apple but it tastes so weird to me, the sourness is like extra noticeable. I don’t think it’s an extra sour apple or anything if that makes any sense ? Like I’m just really tasting the sour notes of the apple… i am 5 weeks pregnant. I haven’t felt nauseous or anything but it’s just tasting dif than normal, and not tasting good to me. Is this considered a food aversion?
