Ovulating late?

Ashley • Proud wife, mom, bonus mom (step-mom), and physical therapist! Expecting baby #2 February 2018. Loving my hectic life!!
Out of curiosity I took and OPK this afternoon. I haven't tested in 2 days since my fertile window is over with. All my OPK before were very faint. This is my test from today. Maybe I'm going to ovulate late? What do yall think?? Maybe I should keep testing and keep BDing??
