When will I start my period?

Anywhere between 10 years old and 21. You should definitely have it by the time you turn 18.

Some signs are vaginal discharge, sensitivity of your nipples, moodiness, change in behavior, cramps.

pubic hair, breasts, and white discharge from your vagina will come out constantly for about 6months to a year before you get your period. usually 2 years after breast deveolpment is when you get your first period could be around 11 to as late as 18. if you do not have it by age 16 see a gynocologist

Had breast for up to a year, pubic hair growing and heavy discharge.

pms....you can google it if you want, but really you get pissed and cry really easy.

also, if you have had discharge (white stuff on your undies), pubic and armpit hair, breasts and you get more attracted to guys......thats what happened to me xP
