Hi,
Welcome to ehealthforum,
The prolonged bleeding and the symptoms that you describe are not normal. It is difficult to comment on the exact cause for your symptoms without examining you and going ahead with further evaluation. You should consider visiting your doctor/gynecologist at the earliest for further evaluation to look for the underlying cause for the vaginal bleeding and symptoms that you describe. Treatment as appropriate (based on examination findings and investigations results) would be started to help you control the bleeding and regulate your periods. Consider being 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.
