Missed ovulation date


So I think I started testing OPK too late and missed my actual ovulation date. Thinking back to my CM, my best guess of ovulation is the 13th. I started testing after that which were all negative. When would you guys start testing for pregnancy ? We actively tried all week consistent of every other day except I got sick on the weekend after the 13th and we stopped. Thanks ‘

Update: tested today. Period is due in 4 days. Do you see the VVFL or evap?

Here’s an inverted photo of that test too for comparison!
