BBT or OPK?

Which one is more accurate? I want to try one. I feel like bbt would be much cheaper? It’s just a one time buy rather than test strips every month.

This is our 4th cycle TTC. If I’m not already pregnant, I’m hoping to shed some light on when I actually ovulate. With my first it was one and done 😂. First time me and my SO had sex I got pregnant.
