Anovulatory cycle? Please help!

When you don’t ovulate one month- do you skip your period all together?

Do you not ovulate again until you bleed? I’m so confused.

I’m 13 days late- negative tests and wondering if this may be why?

But also wondering if I should start opks again in case my body ovulates?

Any information would be helpful as I had a miscarriage in March and no period since.
