Peak smiley 6 days ago, still pos opks

Em

I started testing at cd 12 with clear blue digi and immediately got peak smiley, not even flashing which was a bit early. Now 6 days later I randomly decided to take another pregmate opk, I never do more tests after peak smiley usually and it turns out to be the darkest line I've ever got and appeared less than 1 min after dipping....
