mid cycle bleeding, anyone?

Anita 💓 married 2 yrs, 💍 ttc #1,
Does anyone have 1-2 days of spotting, very light in mid cycle? I had a positive opk about 5 days before, we made sure to BD a LOT ;) but then this past weekend I had spotting! Just a slight amount. I read that spotting can be a sign of ovulation. So did I ovulate late? We've been trying for awhile now. 
So now I'm confused! We BD again... but why is this so complicated! help.
