Irregular cycles and ovulation

Hey ladies! I have irregular periods and have started using OPKS to try and track ovulation. My cycles are anywhere from 30- 48 days. I know you aren't supposed to keep testing once you've gotten a positive opk but I feel like I'm so all over the place, I can't necessarily trust it. So I'm testing throughout to try and get an understanding of my body. I just want to figure out when the heck I actually ovulate!

I got what I thought was my positive opk on CD 13/14 (test not in pic) along with EWCM. Well then on CD 22 I got what I thought a strong positive. Now today on CD 32 I'm getting what I consider the strongest positive yet.

Anyone have any experience with irregular periods and ovulation? When do you think I ovulated? Seems like if I had ovulated earlier in my cycle I would have either gotten AF or a BFP by now. Any input is appreciated!
