Is a chiropractor covered?

S
I tried looking it up online but came up with nothing. Hoping some of yall will know. I'm really interested in going to the chiropractor to ease some of my pelvic pain before I deliver. Does Tricare standard cover any of it? 
Also, the office Im looking at takes Humana. I know Tricare and Humana are linked somehow so does that mean they would take Tricare as well? 
Insurance is seriously the most confusing thing in the world to me.
