I'm 13 and haven't started..?

but I've had discharge for a year. Every girl get her period when her body is organized. It can start as young as 10 years out-of-date or as old as 16. Any age is conventional! Some signs your period may be coming are when your breasts start growing, and when you start getting discharge. Usually your time starts after about a year or more of that. Hope this help! =)
Do you have an actual examine?
