I don't get much bloating or cramping but I get diarrhea a lot,
I have lots of pubic hairs and my longest one is like 1 inch and a halve and I've had it since the beginning of 6th grade and it's black and starting to curl,
I get discharge every day since like one day last summer,
I don't spot at all,
I had a hip cramp so bad that I couldn't even walk,
I don't have that many upper leg soreness ( I ride horses and they get sore does that count?),

I've been so emotional that I cried over a game and I get mad over the slightest of things,

Ahh I see how you feel. And I noticed and getsemani noticed too I was wondering when you were gonna be back lol but it's okay I normally just ask everyone what they are talking about rather than going back but I do understand!

@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!!
