What are my chances of pregnancy?

 My menstral cycle ended Friday 04/01 and my fertile window runs 04/04-04/10. My fiancé and I had intercourse, unprotected and he came inside of me this was on Thursday 03/31, 2 days before my period ended. What are my chances of becoming pregnant since there was intercourse and I will be entering my fertile window. I know the rule says sperm can typically live within the body for 5 days, on what day of my fertile window does my egg actually drop? (I know the egg lasts for 12-24 hours roughly), I have a 25/26 day cycle.
