The wording on this spell is a little confusing to me.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every two slot levels above 2nd.
Does this mean the damage increases when cast as a 3rd level spell, then again at 5th, 7th, etc? Or does it start at 4th, then 6th, and so on?

Spritual weapon is a 2nd level spell. The first part of this description is simply telling you the rules for casting it from a slot higher than it's level, i.e., third level or higher. Many spells have greater effects when they are cast with a higher level spell slot.
The second part tells you specifically what effect casting with a higher slot has and how the spell improves based on which spell slot you use. In other words, casting it from a 3rd level slot doesn't grant any benefit, because that is not two slot levels above second.
The spiritual weapon's damage works out as follows:
