CD 16 POSITIVE!??

I am not sure when I ovulated I was pretty sure I ovulated on Saturday because I had ovulation cramps. But now I'm not sure that would put me at 6 dpo today. I was suppose to ovulate this Monday predicted by the app... I took a test just for the fun of it and I have a light line that was sooo clear when I took the test I waited for it to dry and the picture is edited, but would you consider this positive? It is the TOP TEST the bottom tests are from my previous pregnancy.
