OPK help for newbie please!!

So my period came today - disappointed but also deep down I knew this cycle had no hope. I was 4 days late and had 2 LH surges/ovulations. Weird.

Anyway, glow is predicting my next ovulation date for Nov 5. When/how frequently/what time of day do I start opk testing considering that I'm having some ovulation weirdness? Should I try at the start of my fertile window on the 31?

My SO works on a contract out of town and it's very difficult for us to get together and BD. I pretty much have to tell him "be here in two days" and he works it out (when we're lucky) and comes home. Trying to find the optimal way of predicting when he needs to try

to get home.

Cycle calendar attached. Any advice is appreciated. My daughter was a complete surprise pregnancy in 2015 so I've never really done all this tracking before.
