Endometriosis Support Group
Endometriosis is a common medical condition where the tissue lining the uterus is found outside of the uterus, typically affecting other organs in the pelvis. The condition can lead to serious health problems, primarily pain and infertility. A major symptom of endometriosis is pain, mostly in the lower abdomen, lower back, and pelvic area.

They could donate to any endometriosis awareness organization, I just like the endo march a lot because it's an international movement so it includes all of us endo gals from around the world. But they could also donate to another organization like the Endometriosis Foundation of America (aka Endo Found).
