Irregular Period

I'm 17, in college and my periods are out of control! About a week ago I had period, it was utterly painful and I had a heavy flow. A week passes and I start my period FULL FORCE, again. I'm currently on the last two days but the cramps have only gotten worse and I'm pmsing like hell. Is this normal? Should I be worried? If so, what should I do?
