Period question (girls only plz!)?

O.k. Well usually you get your period the same time your mother did. But, you can get it from your grandmothers or sister siblings. And if your like me, having 1 sister have her period around 13 or 14 and my mom 15 and my other sister 9 it can vary. It also depends if your body is ready. If you already had discharge, that means your body is getting ready for a period. (A discharge is when a women cleans out her . It can be white and moist or white and dry. It can also by yellow and dry. If it is any other color tell a doctor). All girls bodies are different and sometimes your period doesn't have to be related to when your mother got her's.
