Clomid is definitely a mouth supplement that can feel used to trigger ovulation. It works by preventing estrogen receptors during the hypothalamus, and that is an important "hormonal controls center" for the body. When this happens, the hypothalamus is stimulated to release follicle stimulating hormone (FSH), and luteinizing hormone (LH). These are really the naturally taking place ovarian stimulants, which prompt ovulation in a normal pattern.
