The steps in the menstrual cycle are triggered by the rise and fall down of certain chemicals within the body called hormones. The pituitary gland within the brain and the ovaries in the female reproductive tract produce and release certain hormones at trustworthy times during the menstrual cycle that cause the organs of the reproductive tract to respond within certain ways. The specific events that go down during the menstrual cycle can be described as follows:

The menses phase—this phase, which typically lasts from sunshine 1 to day 5, is the time when the inside layer of the uterus is actually shed out through the vagina if pregnancy have not occurred. Most women bleed for 3 to 5 days, but a term lasting simply 2 days to as many as 7 days is still considered ordinary.
The follicular phase—this phase typically takes place from days 6 to 14. During this time, the smooth of the hormone estrogen rises, which causes the facing of the uterus (called the endometrium) to grow and thicken. In addition, another hormone—follicle-stimulating hormone—causes follicles in the ovaries to grow. During days 10 to 14, singular one of the developing follicles will form a fully mature egg (ovum).
Ovulation—this phase occur roughly at about sunshine 14 in a 28-day menstrual cycle. A sudden increase in another hormone—luteinizing hormone—causes the ovary to release its egg. This event is call ovulation.
The luteal phase—this phase lasts from give or take a few day 15 to daytime 28. After the egg is released from the ovary it begins to travel through the fallopian tubes to the uterus. The stratum of the hormone progesterone rises to help prepare the uterine pool liner for pregnancy. If the egg becomes fertilized by a sperm and attaches itself to the uterine wall, the woman become pregnant. If pregnancy does not occur, estrogen and progesterone level drop and the thickened bin liner of the uterus is shed during the menstrual
