I'm 14 years old and i started my period in June 2009 for the first time. Up until this month (August) I have been starting my period every 28-30 days. August the 6 was when i was supposed to start this month. It is now august 15 and i have had no spotting or anything. I am very worried that something is wrong. I am not sexually active at all so i know that i am not pregnant. I keep a record of my periods on a calendar i have in my room. So when i didn't start when i was supposed to i became worried. Because i havent had a period for very long and i don't really know what to expect and i am scared that something is wrong with me. Please help!!
