OPK first time user question!

Amy • Married 5-20-12 to my love since `08 ❤️ Our 🌈 Lucas arrived 5/16 - baby #2 became an 👼🏼 in 9/19

So I’ve never used ovulation tests before. We had sex CD 12 and today on CD14. Does this read like I ovulated today or yesterday? I’m not sure how the peak stuff works :P
