Question about ovulation day cm?

Shannon
So I don't temp or take opks (yet) but for the ladies who do do you notice the most ewcm on the day you ovulate? Does it stop the next day or a few days later? I have been going by my cm to guess ovulation. Glow predicted o day is usually pretty accurate but not this cycle.. It's been a strange cycle as far as fertile cm. Any input is appreciated! Thanks y'all!
