Where'd the percentage go?

Heidi • We are trying again. We have a 2 year old & had a stillbirth prior. And I have a YouTube channel. YouTube.com/heidikimTV
Glow had a place where is told you on any given day what your percentage likelihood of getting pregnant that day was. Now I feel like I'm crazy because I can't find where they posted it. Can someone tell me where I can find it?
