Hi,
Welcome to ehealthforum,
The heavy and repeated bouts of vaginal bleeding (after missing periods and having symptoms suggestive of pregnancy), could indicate chances of early pregnancy loss. Do not delay in visiting your doctor/gynecologist for thorough evaluation to look for the underlying cause for the abnormal bleeding that you describe. Hormonal and blood work-up along with ultrasound scan done will help to look for the underlying cause. Treatment as needed (based on examination findings and investigations results) would be started to help you control the bleeding and regulate your periods. If ultrasound scan reveals retained products in uterine cavity, you will need to have D&C (dilatation and curettage) procedure done to clean up the uterus and stop the bleeding. 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.
