I hate periods

So today I was on the bus home from school and I was sitting next to my guy friend like I always do everyday before and after school. I put a snapchat filter on him and he made a face so funny that I laughed and got period blood all over my jeans, ruined my panties, soaked my pad and got it on the seat I was sitting in. Even though before hand I told him to not make me laugh because when I laugh my period comes out. Luckily I had worn two jackets today so I wrapped one around my waist. To make matters worse when I got home my older brother asked me what was wrong, I told him and then he laughed at me.
