I have heavy period bleeding, and when i wake up in morning in periods days its really messy because of heavy bleeding, what's wrong with me?

Menorrhagia: If this heavy bleeding is new for you, and if it's been happening for more than one cycle, then i would see a doctor to rule out an anatomic cause of bleeding like fibroids or polyps. These can be easily corrected and make your periods lighter and easier. If there is no physical problem, then your doctor may suggest hormones or medications that could help you manage your bleeding.
