Opk with glow fertile days please help!

Angel baby🙏🌈👶
Glow says my most fertile day was yesterday with tomorrow being my last day. I still haven't got my peek day on opk. Does it mean I should get it tomorrow as that's my last day on glow (this is assuming that glow has it right). I'm just a little worried as I've had flashy smile face for 4-5 days 😬
