Late ovulation - CD24

This is my first cycle being off birth control pills. My first 'normal' period came on day 34 (8/28). I started using opk strips three days after my period on 9/5. I finally got a positive yesterday... Which was CD24. I've heard that late ovulation can cause early miscarriages. But I have also heard that it doesn't matter. Anybody else have this happen? Experiences?
