O pain and O date

Is it possible to O a few days after having O pain? Or does usually the pain mean you O that day or maybe the day after?

I had distinct O pain on my right side last Friday. Is it possible I O'd during the week?

I'm confused because I have longer cycles (33 days) and I used an online calculator and it said my most fertile days were yesterday - Tuesday.

That seems too late if I had the pain last friday - 1 week ago? Maybe I will have a shorter cycle this time around (sometimes they are 28 days)?

Honestly i dont think those calandars hold much ground. I think the only way to know for sure is opks or temping, but i would definitely pay more attention and trust your physical symptoms over the calandar.
