Why haven't I started my period?

Hiya everyone I am 13 and I haven't started my period.
could it be because I am tall (5 ft 5)

Thank You x

your height has nothing to do with it. I'm 5'2 and I didn't get mine till the week before I turned 14. Everyone's body is different. weight will affect a girls period. being overweight (a lot overweight) or underweight can cause it to be irregular. don't rush it, it'll come when its time. enjoy being periodless.

xxemjixx,
I don't know if your height has anything to do with it, most likely not. Although two of my friends that are extremely skinny didn't get their period till they were 16-years-old. So sometimes I do think weight/height can play a roll. But, everyones body is different. You're time will come, don't be worried. You should be happy that you don't have it, it sucks!!

That is totally normal, and its not your height. I started mine when I was 12, but my friend didn't start her's until she was 16, and she's just fine. So, no worries, there is nothing wrong with you.
