Re: Irregular Menstruation Problems

Hello, I am 20 years old and I've always had an irregular menstruation from the first time I ever had one. Recently I haven't had one. I was and still am a little worried. I had my last period when I was in Italy over Christmas break which was in December. My period came in the last week of December and went into the first week of January. As stated before, I haven't had one since. What could be my problem? Please answer me ASAP. Thank you.
