Implantation Bleeding Percentage

“It’s a pain like nothing else,” one woman relates regarding her experiences with endometriosis. “Some days I would be doubled over, completely disabled by the pain.”

This woman is not alone. Endometriosis is estimated to affect more than one million women in the United States – most often during their reproductive years. Endometriosis is the abnormal growth of endometrial cells – similar to those that form the inside of the uterus, but in a location outside of the uterus. As the endometrial cells, or endometrium, attach to tissues outside of the uterus, they become endometriosis implants – most commonly affecting the ovaries, fallopian tubes, outer surface of the uterus or intestines, and the lining of the pelvic cavity.

During menstruation, the displaced endometrial tissue continues to act as it normally would; it thickens, breaks down, and bleeds. Because the displaced tissue has no way to exit your body, it becomes trapped and causes pain each menstrual cycle –sometimes much more often.
