Anovulatory cycles in the absence of PCOS or other disorder?

Sa

Hey all! Have any of you ladies simply missed your period in the absence of pregnancy during a random month of the year? I’m 7 days late and having negative HPTs. My doctor said I could still be pregnant (which I don’t believe bc I don’t feel pregnant at all) or just didn’t ovulate last month bc of stress etc. So have any of you ladies not ovulated during a random month like that?
