Advise?! First time using OPKs

Hello! I'm hoping someone can give me some advise.

This is my first time using OPKs to track ovulation and the first month my husband and I are trying for our first. I have irregular cycles lasting anywhere from 38-45 days, been off the pill for about 15 months after being on it for 10 years. Do either CD 21 or 25 look positive? Or maybe close?

I have a couple different cycle tracking apps that say I may be ovulating anywhere from today (CD 25) to this coming Tuesday (CD 28).

Thanks in advance for your response!
