OPK help... positive?

I took 3 OPK’s yesterday. Having trouble analyzing them. The first was at 11:00am and it was a definite negative. (First pic) Then I took another one at 3:00pm and it was much darker, I can’t tell if it’s positive or not. (2nd pic) The last test I took was at 7:00pm and it was negative. (Not pictured) Was my 3:00pm test positive?
