OPK...TTC What do you see?

Kimberly
My husband and I have been TTC since May 2016... starting to track ovulation because of CRAZY long cycles. Last Cycle was 54 days with 13 day periods. Do any of these look positive? Top pic is cycle day 16...then 17,18 and cycle day 19 being the bottom... just Trying to get others opinions. The lines all start looking the same after awhile. Or anybody have an idea of what's going on? Please and thank you for any help.
