Experiencing heavy blood flow during periods? Needing to use double sanitary protection to control your menstrual flow? It may be Menorrhagia. Menorrhagia is a term used to denote abnormally heavy or prolonged uterine bleeding in female. Although heavy menstrual bleeding is a common concern among premenopausal women, most women don’t experience blood loss severe enough to be defined as menorrhagia. In some cases, bleeding may be so severe and relentless. Menorrhagia causes enough blood loss and cramping that your daily activities become interrupted.
