I was very athletic (played softball for 2 teams and fieldhockey) and I got my period when I was in 5th grade. I remember a girl when I was in 5th grade got her period she was out of school for like a week (I kinda think that's really pushing it...) But it I was so scared when I got my period first. I was going to a day-softball camp at a local college which was about 3 blocks away from my house or so. But I had got it the during the middle of the week (since the camp was Monday-Friday) and I got it the one night after the camp. Then I remember this awkward feeling since my dad went up to the college players that instructed us to "take it easy on me" since I just got my period for the 1st time lasts night.
