No noticeable CM?

Kati • Hi im Kati Tess. Im 33 w a 4 yr old daughter. Right now im a sahm while i finish school. My husband and i have been ttc for over a yr. We had a MC last spring but are still hopeful and ttc again.
I'm TTC and my chart says I'm ovulating today but I never notice any change in my CM ever... Why would this be. Its always clear and sticky, sometimes more of it than other times. But I never get the ewcm that you're supposed to when ovulating... Any ideas???
