This is when Glow says I ovulated. I think it's going off of my bbt, because I tracked it. And that's where it pinpoints ovulation, on the bbt chart.

This is the day I got my first solid smiley on my CBD tests. So it was my peak day. I also had a ton of EWCM this day and a couple days after. 
Thanks! Opinions appreciated!
