Once my period was really heavy and I made sure to double up with a tampon and pad. Later that day at school, my crush walked up to me and asked me what was on the back of my pants. I didn't know what he was talking about, so I ran to the bathroom. When I came back, I had to tell him it was ketchup. For the rest of the day, him and his friends were trying to figure out how I got ketchup on the back of my pants. It was HORRIBLE!
