Understanding ovulation & my cycle

Ok so SO works away from home a lot. He left the 10th and surprised me with coming home yesterday evening!

I ALWAYS have ovulation pain. So I never use test to track it I am or not. This last month I woke up the morning of the 14th (early morning) with that ovulation pain. Which was unexpected because it’s always been day of or up to 2 days after this app predicts it. So that would me around 5 days after the last time. And I keep hearing that sperm can live up to 5-7 days inside and wait around for ovulation. Small chance. But a chance.

Now my biggest question, I was reading and seen that ovulation pain can actually happen before or during or even after you actually ovulate…. That alone could make a world of difference in this situation.

Maybe I had the pain the 14th but still ovulated the 16th/17th?

Does anyone have ovulation pain but still test when they actually ovulate that could confirm?

And with the days we were able to try, what could be my chances?
