<a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> says I’m ovulating today. I have been using Clearblue advanced digital tests but only started using them 2 days ago, even though I actually started my fertile window 5 days ago. I have had high fertility, flashing smiley face for the past 2 days and had the same again today.

Is there a chance I could still be ovulating today? Or is the tests maybe not showing peak because I did t start using the tests from the beginning of my window and only started them 2 days ago?
