AF (hopefully not 😉) expected 3/26 cycle buddy?!

Hi friends!! So I'm on CD9 my last cyle was 29 days which is pretty normal as my previous ones have been 28 days.  I am using Glow and Ovia and log the same data each day. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> said I'm in my fertile window starting today and my Ovia all says my fertile window doesn't start until Monday? What do you ladies think? Good luck and baby dust to all! ✨Â
