Glow shows my fertile period as starting, like, three days after my period. I know that's inaccurate. Right now, Glow says my peak day was Friday, but according to my CM, that's not right. I also use another app called My Days, and it says my Ov date is Wednesday, which makes more sense. Currently, my CM is egg white and copious! Guess I'll start taking my ovulation tests again just to be sure!
