Is There A Pregnancy Risk If We Had No Penetration But Genital Contact During Ovulation?

Hi, my gf and I were intimate on Tuesday afternoon. We did not use any protection nor did we have any penetrative intercourse. Nevertheless, we did bathe together and my penis was around her reproductive area. We did shower properly and after bathing, I tried to rub my penis on her bum. I didn t penetrate her bum. After that, my gf used tissue and wiped her private parts and her bum. Is there any chance of her getting pregnant doctor? Based on the Flo app, she is ovulating and has high chances of pregnancy. Should she take the morning after pill?
