I have my periods problem. it does not come one or two months but when it comes, it remains atleast the whole month. please suggest some precautions.?

Abnormal periods: It is not normal for you to bleed this long in your menstrual cycle. You need to see a physician. Bring your menstrual calendar to clinic with you so that you can show them when your bleeding starts, when it ends, and when your next cycle begins. It also helps to notate on the calendar h (for heavy), m (moderate), and l (for light) on the days when you are bleeding for how much blood flow.
