Hi,
Welcome to ehealthforum,
It is difficult to comment on the sudden bleeding that you describe without examining you and going ahead with further evaluation. If symptoms have been persistent, or if you develop any other new symptoms, you should consider visiting your doctor/gynecologist at the earliest for further evaluation to look for the underlying cause (hormonal imbalances, thyroid abnormalities, endometrial problems/hyperplasia, uterine polyps/fibroid, pregnancy, etc). Treatment as appropriate (based on examination findings and investigations results) would be started to help you. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
