So confused

Ta

I’m starting to get a little irritated with my OPKs. Top is yesterday afternoon and bottom is at 2:30pm... the past 4 days I’ve had ewcm and now it’s turning into creamy lotion like. Yesterday was the darkest opk I’ve gotten so far.... I just want to know when I ovulate 😭😩 CD 15. (I usually take one am and early afternoon.) (by the way, I’ve been getting lines like today for the past 7 days.....)
