Opk confusion

Le

Okay so normally I ovulate a little later in my cycle. Normally around cd 16 in when it’s typical for me, or at least from my logging.

But the last two days I’ve gotten super dark opks like darker than the control line. Which yes I know that means is positive but normally my opks only get as dark as the control line no darker. Well today’s cd 20 and idk what’s going on. My first positive opk was aug 6th and I also had spotting that day so I had assumed that I in fact did ovulate. But now that I’m getting super dark opks I’m so confused. What do you ladies think? I’ll post pictures in the comments because it’s not letting me here for some reason or another.
