Have i stopped growing???? :O?

i think i've stopped growing,since i already had my period for about 2 years.My parents aren't tall.My dad is 5'8, my mom is 5'2 And i'm 5'2 too.I know i've stopped growing cuz over the last year i was about 1 millimetre away from touching the basement ceiling.And it's been a year and i still can't touch it.And i've also measured myself and i'm not growing.Have i stopped growing??i'm 13!!And if i have,is 5'2 too short? When i was little i was always the tallest in the class,and i thought i would be so tall that it would be weird,and now i'm worried that i'll be too short :(
