Extremely irregular period! HELP

I have had my period for over 2 years now, and it's still extremely irregular! My cycle has never been the same length, and ranges from 30-60+ days. One month I'll get my period after 40 days, and the next month 63 days, then the next month 54 days, etc. My period is so unpredictable and I never know when to expect it. Just wondering if this is similar to anyone else?
