If she is your birth mother, she is your mother by necessity of implied Definitions, and physics. Some folks, who were adopted at birth, regard the adoptee's as the true parents, but the Fact is, you can only have one Birth mother, so you could refer to her as, "My Birth Mother" this does not prevent you from calling your adoptee Mother, Mother as well. The Traditional Roles of Females Via History, would more then suggest that "Mother" is not necessarly the Birth Mother, but rather the Care Provider of any and all, as in Motherhood.,,Mother Earth, Mother Teresa, Mother Nature, Etc.
