17 days since positive OPK

Ch

It’s now been 17 days since I got a positive OPK, I believe I’m 16 dpo. I stopped testing after I got this results (pics below) but now I’m concerned that I maybe stopped testing too early and that I may have gotten a stronger peak a couple of days after... would love people’s thoughts and experience.
