First Time. Help, please!

Sh

Can someone explain this to me? This is my first month using ovulation tests and idk what I'm looking at (sorry if that sounds dumb). I took these

(1.) Yesterday evening around 6

(2.) This morning around 7:45 and

(3.) Today at about 5:30.

How do I read this? Have I ovulated already? Or not yet? Based on these, how do we know the best time to start trying?

Again, sorry if this is a dumb question, I just want to make sure we are using these right!
