Mine are no fun, but it could be far worse. Like a weird number of ladies out there and on here, I know a few dudes that previously thought women just had random moodswings monthly and that's what a period was. Funny everytime I think or hear about it.
In terms of personal funnies(?), I had a lot of period-related incidents that sent me home from school when I was a teen. The last one I dealt with before my cycle started pumping the brakes a bit was when I was seventeen. The teacher came up to help me with something after I'd asked for it during class, I felt a brief pinch in my lower body, then a pain in my upper back before I fainted. Eventually woke up on the floor with the teacher next to me., and while none of that sounds too funny, I sincerely thought I had some kind of seizure off of the bare essentials I knew of how those worked. So I kept loudly, repeatedly asking her if I'd pissed myself. I hadn't, but I'd gotten a mild concussion from hitting my head on the edge of a table. I even had a bump, just without the pain.
Went to the doctor after getting picked up and they couldn't tell shit from piss what exactly had happened beyond the "proctalgia fugax" reaction (aka muscle spasms in/around the ass that can make your other muscles briefly freak out). Concussion itself was cleared within a day or two, no harm done!
