OPKs help please

Laura • After 4 years of TTC, finally conceived my miracle baby boy and gave birth in June 2020.
Hi ladies! I need help determining when I am ovulating. I feel like I am the only woman who cannot pinpoint when I am ovulating on the exact date. I have been taking opk's consistently for the last 4 months but i'm still not 100% sure of what day I ovulate.
Please take a look of my current tests and give me your opinion on when you think I am ovulating. Today's test has been the most positive so far (darkest line). And I have had pelvic pain the last two days...especially on my right side so maybe that is the ovary that will release the egg this month.
We have been trying for exactly 1 year now.
