How soon to track AF...

How soon after your AF do you start <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>! I am currently on my AF, and don't want to miss out on a single thing. This will be my first month trying OPKs, any advice would be good! 
Test kind? How dark should they be? When should I test (morning, noon, night)? How long do you test? When do you stop after your surge. The only bad advice (I feel) is not giving advice! Should I test with FMU or SMU or EU. Second morning urine and evening urine
