The menstrual phase. During the menstrual phase, pregnancy occurs when an ovulated egg is fertilized by a sperm and implants itself in the lining of the uterus (the endometrium).Progesterone and estrogen levels drop if pregnancy does not occur, causing the uterus to shed its unused lining and expel it along with blood (menstruation).here is a basal layer below the shed functional layer, which forms a new layer of tissue for the following month, thickening the uterine lining. Female hormones regulate this monthly cycle, during which the uterine lining is shed and expelled only to be formed anew.
