Hi,
Welcome to ehealthforum,
If the bleeding is light and persistent, it could be indicative of pregnancy possibility. Other causes for the prolonged bleeding that you describe include hormonal imbalances, thyroid abnormalities, anemia, bleeding disorder, vitamin deficiencies, probable ongoing miscarriage/incomplete abortion (especially if associated with abdominal cramps and presence of clots), endometrial hyperplasia, etc. It is difficult to comment on the cause for bleeding that you describe without examining you and going ahead with further evaluation to look for the underlying cause. Consider visiting your doctor/gynecologist for examination and further evaluation to look for the underlying cause. Treatment as indicated (based on examination findings and investigations results) would be started to help you control the bleeding and regulate periods. If pregnancy is suspected, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets confirmed, ultrasound scan done will help to confirm the gestational age and viability. 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.
Take care.
