Clomid is actually an oral supplement that can be used to stimulate ovulation. It works by blocking estrogen receptors during the hypothalamus, which is an important "hormonal controls centre" for the figure. Whenever this happens, the hypothalamus is stimulated to release follicle stimulating hormone (FSH), and luteinizing hormone (LH). These are really the of course happening ovarian stimulants, which prompt ovulation in a normal pattern.
