Ovulation discharge?

What should your discharge look like the day before ovulation/day of ovulation/jus after ovulation?

Me and my partner dtd Monday 20th Jan before he went back to work. Which should be 3 days before ovulation as I am supposed to be ovulating today according to app and have been doing Clearblue ovulation tests which have been showing high fertility the past 2-3 days.

Sorry if this is TMI but today I have tacky/paste like cloudy discharge. I’m not sure if this means I have maybe ovulated early or late? Or whether I am ovulating today?
