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 <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> is also telling me this week if fertile week...what cd did you get your smiley?
