Marisa, I also did not have my period until 16 and this is normal. Ask your mom when she had hers. If it was late, most likely yours will be too. If you do not have it by the time you turn 18, then you should see a doctor. Don't give up hope! You don't want it!! Enjoy life without. Skinny people usually have theirs later by the way (I am 5'4" and weigh 110 lbs) How tall are you and what do you weigh? If you are realllly thin you could not have enough body fat to have your period and that could be the problem. Hope I helped!
