Day after ovulation pregnancy possibility??

According to this app (its been 100% accurate as far as my period predictions and I log my information often) I had sex on the day after I ovulated. Whats the chances of pregnancy? I have no signs what so ever of either pregnancy or my period aside from a shit load of cervical mucus like it feels like I’ve just been came in,, and some slight twinging/discomfort in my right side lower abdomen. I usually get cramps the night/day of my period but the other day I had to wake up and have pain relief for it. Also, my breasts are sore, but that’s no biggie because theyre always sore from ovulation to my period time due to hormones. What do you think? Has anyone had similar symptoms/experiences? What symptoms did you have?
