Missed ovulating?

Crystal

Has anyone ever skipped a month of ovulating? I’m just curious as to this because I know my exactly when my body is ovulating because of my cm but I’ve noticed that I haven’t had it and I was supposed to be ovulating yesterday. This isn’t the first time I’ve noticed it either. Just wondering if anyone has possibly had the same thing and could shed some light. Maybe I’m just being paranoid lol.
