I've had abnormal menstrual cycles for approximately 5 years. Recently the past year I went 6 months almost 7 without a period. Then I started what I thought was a menstrual cycle that last day or approximately a week and a half. Shortly after that ended I started randomly bleeding and since then I have been having days where I'll bleed very heavily then it'll stop a couple hours later or it'll keep going. It's off and on, I can go one day without and the next day is the worst. Vice versa.
