Ovulating late

November 20th-26th. I didn't have any cm until the past few days -very little though. I think I'm ovulating today. I had the stretchy, egg-white cm this morning. Unfortunately we couldn't bd. Hopefully I'll still be ovulating tonight. Anyway, af is scheduled for December 9th. Anyone else ovulate that late, or close to their period? My cycles don't seem to be even running for 28 days anymore. It's just changed in the past year since I've been off birth control.
