Discharge before ovulation?

Catharine

According to this app and another one I’m supposed to be ovulating in 2 days I stop tracking with opk cause it stresses me. I am tracking with my bbt. But today I woke up with this discharge is this the kind of discharge you get before ovulation starts? I had wiped the first time which was more brown and ewcm but I forgot to take a pic but this is now that I went to the bathroom.
