Taking opks every day after ovulation

Have any of you ladies used opks to detect early pregnancy? I’ve been charting my fertility and I’m 2dpo right now and still taking opks and the line isn’t fading like it usually does, I’m thinking of taking the opks every morning until I start taking hpts at 7dpo to see if the line stays dark or fades to almost nothing.

This is our first month trying but I’ve been taking opks for a couple months now to kind of get a feel for how my body works. Usually a few days after I ovulate the line is barely there anymore but it still looks pretty strong, I don’t want to get my hopes up😅
