Period Horror Stories!

Mine was when it was my first year of having a period and I was at my friends house and I had a heavy flow that day but thought I would be ok, nope! We were sitting on the couch and when I got up there was blood all over the couch! We tried to clean it up with paper towel and ended up turning the couch cushion over lol. So embarrassing. I had blood clots and everything that day. Fuck periods. What's your story?
