Confusing OPK

Took a non digital opk this morning and to me looks like a positive. Digital said no this morning tho and have me a positive yesterday (although the line always looks lighter and fainter on the digital to me when I pull it out and the blue dye looked smudged over in the positive yesterday morning) here's the non digital pic... My temp was 97.22 (most AMs since AF have been 97.1-2ish)... BDed last night. Plan on continuing. What do u ladies think? (And the non digital looked like this after 3 min like the directions say. I didn't wait any longer to read my result)
