Ovulation ? Can someone chat ?

So my first day of ovulation is today my first green day, but me and my partner Had sex on Friday before he went away for 3 weeks is it possible for me to get pregnant 3 days before ovulation because now I know it's early but I'm getting a lot of left stomach pains and gooey white discharge (sorry if that is tmi) and i have been drained since yesterday don't want to do anything
