-Menstruation: the shedding of the uterine lining. Levels of estrogen and progesterone are low. -Follicular phase: The time between the first day of the period and ovulation. Estrogen rises as an egg prepares to be released. -Ovulation: an egg is released from the biggest follicle and delivered to the falloppian tubes. Here it can be fertilised or, if not, it dissolves in about 24-48h. Very high levels of LH in this phase -Proliferative - luteal phase: After the period, the uterine lining builds back up again. Sudden increase in progesterone levels after ovulation
