POSITIVE OR NEGATIVE OPK?

My fertile week ended today, the past two days before I had EWCM, and slight boob tenderness and today the boob tenderness is a lot worse... does this happen after ovulation? Or am I ovulating late? I took this opk today and the line is dark but not as dark as the control line, but my test lines have never been that fully shaded. What do u think? Im so confused on if i already ovulated or havent yet?
