Ovulation

Okay, so I've been taking digital ovulation tests since Saturday which would have been the 11th cd.. and I still haven't gotten a smiley face but the lines were darker than others Monday and then darker again yesterday cd 16. I cramped really bad yesterday...and I know people say the lines don't matter, but they seem to be getting lighter except for yesterday..I'm so confused ....and then eve is also telling me this week if fertile week...what cd did you get your smiley?
