Trying to plan a little.. OPK? BD?

As I'm nearing the end of AF week and getting closer to fertile week.. I'm trying to plan ahead a little and would love some insight. Last month was my first month doing opk testing. I only got a chance to test 2 days because I got a low reading the first day, then straight to peak the very next day! Totally skipped High. Started testing at cd7. This month.. I'm going to start testing right away after AF because I think I might ovulate really soon after AF. Does anyone else ovulate super soon after AF? I'm not quite sure I get the opk thing.. I have clear blue digital. OR should we just try to BD every other day this whole month? LOL
