What are my chances? Did I miss it this cycle?

I have 35-38 day cycles. Yesterday was CD21 and I was ovulating. I always get extremely painful ovulation cramps. Anyways, My Hubby & I are both military so our schedules are far out there sometimes to say the least. We BD's 3 days ago and 2 days ago, but did not BD the day before ovulation, or yesterday... did I miss my window? I hear so many different time lines on how long sperm live... I'm just soooooooo worried i missed my window of opportunity for this cycle :(
