Hello dear user, thanks for consulting Healthcaremagic and sharing your query, I kindly suggest to visit the doctor, after 4 months straight bleeding the causes it could be different, cervical polys( benign) endometrial diseases (polyps, hyperplasia, cancer, inflammation, infection) perimenopause, stopping birth control pills, fluctuating hormone levels, some drugs side effects, severe systemic disease and much more. I advice you to eat a high protein diet, drink enough fluids, take a vitamins supplements and limit your physical activity to avoid further complications. A gynecologist should be consulted only an speculum examination will help you with the right diagnostic and proper treatment. Please kindly rate if my advise has been helpful Wishing you a good health Dr Tania Portelles-Driggs
