For the past 5months or so i have had my period on and off, what should i do?

At this point: You'd be best served by an in-person evaluation with your primary care doctor. But in the meanwhile you should try to attempt to better document the timings of your period, the length of your bleeding, the heaviness, and any other associated symptoms like odor abdominal pain, painful intercourse, vaginal discharge. This information combined will help better guide your doctor as to possible causes.
