Hey OP here! This actually happened when I went on a two week trip to Italy back in the beginning of March. The rest of the trip was actually great I toured the entire country! As for what happened, I was on my period with a pad on and it took me 6 hours of the 8 hour flight to fall asleep, but as soon as I did fall asleep all hell broke loose apparently. I didn’t tell the flight attendants because I was too embarrassed so I kind of just got up and awkwardly waddled away. Could have been worse though!
