OPK confusion

Va

Hey y’all hoping you can help.

I have been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> using OPKs & the digital photo scanner.

My OPK was pretty high last night and this morning’s FMU provided a lighter color line. Does that mean O has already happened? The photo test reader says my peak was yesterday. We’ve been BD every other day (blue triangle below) + second day in a row yesterday. Should we BD again today?
