I'm 11 how many years till I be on my period I know it's 11 to 14?

Just be patient it will come,

I am 11 also and on the contrary have had my period. It is awful, annoying, and just a pain in my butt. Plus, there is no set age for your period to come. Hope this might have helped!
P.S. Don't hope for your period, it stinks!
