I almost shit myself during the geography exam

I woke up really early because of the stress and ate my breakfast around 5am. I went back to sleep and overslept so didn’t have time to go to the toilet before having to leave for school. 5 minutes into the exam I started having stomach pains but I didn’t want to put my hand up because I was too embarrassed. When there was around 20 minutes left I knew that shit was going to go down and a couldn’t stop a rancid fart from leaving my ass. It lasted around 15 seconds and I wanted to Eva smith myself after it happened. I’m in the school bathroom suffering rn.
