Odds of pregnancy

My SO and I had sex on fertile day 1/6, and 2/6 (going off of Eves predictions) today is 4/6. My projected ovulation date is Sept 4 (6/6) but I already feel the side ache.

What do you think my odds are that I’ll get pregnant after BD’ing so early in my fertile window? Days 1 and 2 were our only opportunities this month.

EDIT: I know the overall odds, but for that early in my fertile window. I just wiped off a glob of clear stretchy discharge too so I take it I am in my fertile period.
