Well, this is mine. I was at home and I was playing on the computer when I needed to go to the bathroom. I went and saw this HUGE bright red stain on my underwear, but I thought it was spotting. I just got new underwear and continued to play the computer game when I was done in the bathroom. It happened again for four more days. Then I decided, "next month I will ask the doctor at the appointment." So I did, and the doctor said I was starting my period! :D
