Anonymous, hey this sounds like you could get it soon, but also some things say you won't get it quite yet. Some of the cramps your describing could be a sign of your period, but your usually won't get your period until you start having discharge.

@Jaye, The more you exercise the later your period is most likely to come, but just because you run a lot does not mean your period wil never come. I know a girl who was very athletic and ran a lot, but she still got her period. it was later than the girls in her class (16) but sh still got it and is healthy.

@KAt Chan, It can be anywhere from a bright red to brown, but for your first period I would expect a darker color. YOu might not even realize you have it, some girls think that its poop. (sorry, I know akward.)

@H gang, good luck!

@Ella, THanks!!
