Do you typically ovulate 12-36 hours after your FIRST positive or MOST positive? I’m confused!

I got a positive on the clear blue advanced digital (static smiley) on CD 16, when I got very close to a positive on the easy @ home strip. But the next 2 days I’m getting peak results on the easy @ homes still. So question is when do you think I’ll ovulate?? Of course I worked night shift the last 2 nights and was up with my toddler last night so my bbt is going to be no help
