Iit i got so nervous i thought i felt an orgasm?

I needed to hand in the most important document of my entire life and I realised I was not gonna finish on time. I had 5 minutes left and I still had to fill up a whole chart. I got so stressed... as I was getting stressed, I also felt like tickling in my vagina, and the usual pre-orgasm feeling. Am I crazy? It was the worst moment of my life stress-wise.
