When do you think my period will comme?

I am 12 and 4 months, I am 5"4 and 116 pounds, I am an A cup, I have had discharge for like 4 months or so, I have had pubic hair for a year and a half, arm pit hair for about 7 months, I have cramps, head acs, back pain and cravings. My mom got hers wen she was 16 but on the other side of the family they all got it at 10-11-12 years old. Wen do you think I will have it around.
