			Endometrium breaks down, menstruation begins. The cells of endometrium, secretions, blood and the unfertilized ovum constitute the menstrual flow. Progesterone and LH production is reduced
		
		
			
			Follicular phase (proliferative phase)
			
			$6-13$
			Endometrium rebuilds, FSH secretion and oestrogen's secretion increase
		
		
			Ovulatory phase
			$14$
			Both LH and FSH attain a pea level. Concentration of oestrogen in the blood is also high and reaches its peak, Ovulation occurs
		
		
			
			Luteal phase (secretory phase)
