Trying to figure out around what days I had intercourse on to become pregnant? I'm due on November 3rd and my conception days are between Feb 7th and 15th. How do I calculate exactly when I had intercourse to become pregnant?

No, and actually conception days are not exact, even "due dates" are educated estimates.

Conception dates can be estimated give or take about two weeks at very best.

But really it does not matter which date you conceived, sorry it is all estimated dates
