Sex AFTER ovulation, what's too late?

My cycle has been super weird this month presumably since I traveled abroad when I was supposed to have been ovulating (w/o DH and to a developing country so I wasn't checking). I was supposed to get AF 6 days ago. Instead of AF I had what I am now realizing was EWCM starting thurs through Saturday. I had lower abdominal cramps Friday night and was still thinking it was AF coming. We didn't BD until Saturday afternoon. Any thoughts on when I might have actually ovulated and what my window was? Think I most likely missed my window?
