CM question

Alex • Married. 29. Boy Mama to Remington, our rainbow baby 🌈 ❤️

Hey! So last night I took an opk and it said negative. I am at 8% chance of ovulating today according to glow and I have lots of clear, stringy cm which I know normally means it’s fertile. I’m just confused since the opk said no last night and I’m only at 8% chance today so just curious on y’alls thoughts 💭
