Please read and answer.

Just wondering how likely it is to get pregnant when my boyfriend put his penis in me for five seconds? There was no cum, no precum that I know of, and he peed right before. Once I realized he had the tip in, I made him stop because he didn’t have a condom on and I’m not on birth control. I am also in the middle of my cycle and this app says I’m ovulating. (It says 33% chance of pregnancy). My last period was around 8 days ago. I just need help because I didn’t want to take Plan B anymore since I’ve taken it a few months ago.
