OPK Confusion

Ma

Which do I go by? I got my peak yesterday... I tested last night and it was fading. Then this morning it was the same color as the control, so considered positive. Not nearly as dark as the one I had yesterday. Which do I go by? This is my first month using opk’s and I’m pretty confused. When do you think I actually ovulated? Now bc of my test this morning premom and glow are both saying I’m ovulating today instead of yesterday
