My period normally last 3 days, sometimes 3 1/2 days. Last month it lasted 2 days and this month it came and it is very light. Should I be concern?

Many things affect your flow such as stress and diet. How old are you? Periods will change as we mature.

Are you getting regular exams?

I am 33 years of age. I am do for an exam

When you get your exam bring up your concerns to your gynecologist. He/she will be able to ease your mind or shed some light.
