Positive OPK? Second month TTC #1

First time ever doing one of these and according to Glow and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Period Tracker</a> I'm ovulating tomorrow? Is it a positive and if so when is the best time for us to have sex we've had sex every day of my fertile window so far apart from yesterday because we were so full after our Christmas dinners but even now I'm stressing that I've missed the prime time. Someone help😂 This is only our second month of trying but last month broke my heart!
