Okay where to begin.

I am 18 years old and I have never been regular(you know in the period sense) it seems like whenever I have a month that is traumatic in the past it comes, but regardless it never does by its self. I started when I was 16 and even then and now I am very infrequent (yet I am fully developed regardless its pesky problem).

I haven't gotten it in December at all. And I am wondering what can be helped with this. I heard the pill helps with adjusting hormones. Is that my problem low hormones or maybe more? Has anyone else had this problem and would like to share what they did for help? Or is it a case for the gyn to step in? I am very confused by this.

Thank you for your help or suggestions
