what are my chances?

hey guys so according to glow today I'm supposed to be ovulating and says i have a 22% chance of pregnancy. Well i didn't know this till a couple mins ago. Well i had unprotected sex earlier. He didn't cum in my vag he came in my butt. Anyway what are my chances. Also before i get lectured, yes i am old enough to have sex, I've had unprotected sex with this guy before, i know at anytime during sex there is a chance of pregnancy I'm just curious because there is a higher rate. Please no rude comments I'm just wondering.
