What is my ovulation day based on my strips?

Hey y’all! I wanted to post my ovulation test strips to make sure I’m reading these correctly. I thought my “peak” was on 5/11 reading my ovulation strip in person, even though the Premom app said 5/12, so I counted in the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> my ovulation day as 5/11. If that’s true I would be 13 DPO. However I wanted to ask you guys, does that sound right? Or would I count 5/12 as my ovulation day and I’m really 12 DPO? I had a

VFL result from a FRER test from this past Friday but since then, my pregnancy tests (I took a FRER and aClear Blue +/ - yesterday afternoon and a FRER on FMU today) looked negative. I am still praying for a positive pregnancy test, and that the VFL I had Friday afternoon is a true positive, even though since then I have not had another positive test. Thank you so much for your help!!!!!
