Does this seem too dark for CD5?

Ashley

Kind of freaking out a bit here. Cycles are usually 28 days but for whatever reason my last was only 21 days and I ovulatee on CD7, completely missing any chance I had of TTC. Started my first cycle with Clomid and I still have 2 days left and this is my OPK on CD5. Does it look like I'm going to O sooner than expected?
