Ovulation wrong on Glow?

Question

AF not supposed to show up until a puns 12/21. Glow said my most fertile day was Sunday so I'm assuming that was the day I ovulate. This morning I woke up with very very faint cramps. Just seemed odd. A different app tells me I am ovulating today. Could Glow be off and maybe I am ovulating today?  Has anyone else found that Glow was maybe off by a day or 2?

Answer

every app i had told me a different ovulation date so i calculated it myself and checked cm and glow was way off lol

Answer

Yes. I've been ttc for five months and nothing was happening. So, this month I used an OPK and I ovulated the week after Glow's predictions.
