School Trip Overnight

I got my period when I was 12 I'm still 12 but what the heck on April 5th 2012 every year the 6th grade class goes on a trip to a place called ferry beach ecology school we got there and things were good it's one of those overnight trips. I was my dorm with my friends some flat chested not even close to puberty. I was falling asleep then I got cramps I thought it was what I ate so I just fell asleep. In the morning i got up to go to the bathroom I went pee and looked at the toilet it was a bloody mess then I looked at my under wear they were coverd in blood and we are assigned shower times mine was at night I was so nervouse I used toilet paper and it was a heavy flow I wasn't prepared for that moment but my very close friend who already got her period had extra pads and gave me some but she only had a couple and she gave me 1 and we had 3 more days of the trip to go so I went to the nurse there and told her she gave me tampons and pads and of corse being who I am I told her that they were cheep and huge and I refuse to wear them at that moment of me looking at smaller pads my crush walks in he starts walking over and looks at the box filled with Ramon's and pads and gives me pat on the back and leaves when I got back to my dorm there was blood all over my bed I didn't even notice and all my dorm buddies looked at me and said that it's normal so I took out my extra sheets and changed them later that day I tooka shower and went to bed hoping to be home soon when the coach but dropped us off at the school I stilled had and hour before my parents could pick me up so I took extra cloths and pads from my bag and took a shower in the locker room later my mom picked me up and I told her she td me it's all apart of growing up but my dad still doesn't know but I would like to thank my school in mass. For having showers thank u st marries
