Faint ovulation test lines

Tiffany • Sat, Mar 04

I've had faint lines on my ovulation strips for the past 3 days, this pic is today's test that I took at 3pm and it's just a tiny bit darker than all the others I took. Wondering how opks work? Does this faint line mean I'm ovulating or should be soon? What will the line look like when I'm ovulating? Anyone have pics of their test while ovulating?
