Ovulating tomorrow? Or missed it??

Brianna • Little Bubs in the clouds 👼🏽👼🏻 👼🏼👼🏻 , finally got my double rainbow 👶🏻🌈

Hey guys so I'm not new to tracking my ovulation but I'm unsure of what's happened as this happened to me this week but not before. I usually take my tests around lunch time so when I though I started to get a positive on CD 11(yesterday) I thought I'd take another one last night to see if it was going to get me a positive. But as you can see with the PM one the line got fainter so I thought I missed it but I just took one today (CD12) and it's a positive.. was the second CD11 test faulty or?? I'm confused and was wondering if any of you guys know??
