Hi,
Welcome to ehealthforum,
If the bleeding has been heavy, along with persistence of clots, it is not normal, and should not be ignored. Consider visiting your doctor/gynecologist at the earliest for further evaluation (or follow-up check) to look for the underlying cause. Get started on treatment as indicated by examination findings and investigation results to help you control the bleeding and regulate periods. 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.
