Period????????????????????????…

Ok so I have around 3 main questions to ask you. First one is, every website I read they say that you should get your period around 2 years after breast development, and about 6 months after getting discharge. (Yes, I do know that these varry from person to person, and that Im not listing pubic hair and other things because thats not what Im wondering about.) But it will be 2 years from breast development this month exactly, but Ive had discharge for almost a year, so which one should I be reffering to, to know about when I'll get my period? Also is it normal for me to always think that every time I feel lots of discharge Im always thinking (and really believing) that its my period, and every night and everytime I go to the bathroom I always expect (and really believe that I will) see my period. Is this ok or normal? And lastly, when I do get my period , how should I tell my mom?
