I found the answers myself. I will post it here incase there are others who feel like their head is spinning about this whole endo diagnosis...
Stage One - few endometrial implants, most often in the cul-de-sac in the woman's pelvic area.
Stage Two - mild to moderate levels of endometrial implants affecting one or both ovaries.
Stage Three - moderate levels of endometriosis with implants in several reproductive areas, perhaps in one or both ovaries.
Stage Four - the most severe of the endometriosis stages with widespread endometriosis implants throughout the pelvic area. The more widespread the endometriosis, the more likely fertility problems will be experienced.
