Looking for guidance

Currently in my tww but in the event we’re out this cycle I would love some guidance on when to BD. I try to do something different each month but the only thing that’s been pretty much the same is when we BD. So maybe that’s what needs to change? Am I just obsessing? July will be our 5th month ttc.

1. I use the Mira fertility tracker

2. BD day before, on and after my higher level reading (also use cheap OPKs to see when it begins to get darker)

3. Also tracking my bbt

4. Regular cycles and off birth control since sept 2019
