Googley - that's how I hid it from my parents was the old toilet paper trick. One day at school thought I started and, because I had hid it from my parents and, therefore, had no pads or tampons, I bled right through my jeans. (of course we were on a field trip and I couldn't run to the restroom).

eve - 7! That's crazy! Glad that wasn't me or I would have kept it a secret for a decade!
