hey, i saw ur question (it was about y u didnt get ur period wen ur mom and sisters did) welll... although alot of ppl think they get their 1st period wen their moms did, thts a MYTH! chances r ur sisters just got it randomely at the same age as ur mom got her first. my mom was 15, my sis was only 11, and im 12 1/2 and i just got it a day ago (sry tmi) and if u notice ur getting cramps, backaches, migranes, tht means its coming in a lil bit! i got cramps and pms and then 1 week later i got it, also if u get discharge, you'll get it around a yr to a yr and a half after u start getting discharge, and plzzz dont stress about it becuz EVRYONE(well grls) will get their period eventually, i hope i helped <3
