Re: period problems
For some girls, it takes longer than others. I know a girl who started at 10 and her older sister didn't start until she was 15. I think you should just relax and be glad you're not cursed yet. Trust me, once you do get it, you will want to stop it because of how annoying it is!
My suggestion is that if you still don't get it by the time you are 16, have your mom take you to the doctor for a check up. They say that women who have their period very young and go into menopause late have a higher risk of certain cancers. So, don't be in such a hurry to get it. The longer it takes, the better it is for you healthwise.
