I am 13, but my mom got her period when she was 16! The weird thing is that I have a discharge which I had for about a year. I didn t think you were supposed to get it for this long. But then I remember that I am supposed to get it when my mom did. But can you really have the discharge for 4 years? (thats not really my question) I m not sure, I get headaches often, and randomly get cramps, I keep thinking I m going to get my period, but then nothing happens! Do you know about when I would/should (or on average) get my period?
