Ovulation over?

So after 1 year and 2 miscarriages I decided I didn't want to use opk's anymore, it just added additional stress. I'm BDing every other day and just notice my CM. My question is, how do you know ovulation is over? I had ewcm for a few days, only one really heavy day (the 20th) 21st it became less, and now 22nd I barely notice any and its not ewcm anymore, it's sticky/cloudy/clumpy. Would that normally mean I ovulated yesterday? Or today even though I'm basically fully dry? Any input would be appreciated 😊
