I had my first period when I was 14 and they came once a month for about a year and a half. Then they would be late...like a month or so, then grew to 3 month late, then 5, then 7....my last period was Aug. of 06. So its been almost 11 months...whats the deal?? I dont have any type of pain, my diet is fine, my stress level is normal for an 18 year old going to college I suppose. Im just worried it could be something major that need surgury or will hurt my chances of having children later on.
