What does a womans cycle look like
Back to Health A to Z. Period pain is common and a normal part of your menstrual cycle. Most women get it at some point in their lives. The pain sometimes comes in intense spasms, while at other times it may be dull but more constant.
The first part of the cycle prepares an egg to be released from the ovary and builds the lining of the uterus. The menstrual cycle is more than just the period. In fact, the period is just the first phase of the cycle. The menstrual cycle is actually made up of two cycles that interact and overlap—one happening in the ovaries and one in the uterus.
The brain, ovaries, and uterus work together and communicate through hormones chemical signals sent through the blood from one part of the body to another to keep the cycle going. A menstrual cycle starts with the first day of the period and ends with the start of the next period. An entire menstrual cycle usually lasts between 24 and 38 days 1 , but the length may vary from cycle to cycle , and may also change over the years.
Cycle length changes between menarche when periods first start during puberty and menopause when periods stop permanently 2,3. Understanding the menstrual cycle is important because it can impact the body from head to toe.
Some people notice changes in their hair , skin , poop , chronic disease symptoms , mental health , migraine headaches , or the way they experience sex at different points in the menstrual cycle. Hormonal methods of birth control prevent some or all of the steps in the cycle from happening, which keeps pregnancy from occurring.
Read on for the breakdown of each phase of the cycle and what is happening in the uterus and in the ovaries. Menstruation: The period —the shedding of the uterine lining. Levels of estrogen and progesterone are low. The follicular phase: The time between the first day of the period and ovulation. Estrogen rises as an egg prepares to be released.
The proliferative phase: After the period, the uterine lining builds back up again. Ovulation: The release of the egg from the ovary, mid-cycle. Estrogen peaks just beforehand, and then drops shortly afterwards. The luteal phase: The time between ovulation and before the start of menstruation, when the body prepares for a possible pregnancy.
Progesterone is produced, peaks, and then drops. When: From the time bleeding starts to the time it ends What: Old blood and tissue from inside the uterus is shed through the vagina.
Each menstrual cycle starts with menstruation the period. A period is the normal shedding of blood and endometrium the lining of the uterus through the cervix and vagina. A normal period may last up to 8 days 1 , but on average lasts about 5 or 6 4.
When: From the start of the period until ovulation What: Signals from the brain tell the ovaries to prepare an egg that will be released. During the period, the pituitary gland a small area at the base of the brain that makes hormones produces a hormone called follicle stimulating hormone FSH.
FSH tells the ovaries to prepare an egg for ovulation release of an egg from the ovary. Throughout the menstrual cycle, there are multiple follicles fluid filled sacs containing eggs in each ovary at different stages of development 5,6.
About halfway through the follicular phase just as the period is ending one follicle in one of the ovaries is the largest of all the follicles at about 1 cm 0. This follicle becomes the dominant follicle and is the one prepared to be released at ovulation. The dominant follicle produces estrogen as it grows 8 , which peaks just before ovulation happens 7. For most people, the follicular phase lasts days, but this can vary from cycle-to-cycle 4.
When: From the end of the period until ovulation What: The uterus builds up a thick inner lining. While the ovaries are working on developing the egg-containing follicles, the uterus is responding to the estrogen produced by the follicles, rebuilding the lining that was just shed during the last period.
This is called the proliferative phase because the endometrium the lining of the uterus becomes thicker. The endometrium is thinnest during the period, and thickens throughout this phase until ovulation occurs 9. The uterus does this to create a place where a potential fertilized egg can implant and grow When: About midway through the cycle, but this can change cycle-to-cycle.
Ovulation divides the two phases of the ovarian cycle the follicular phase and the luteal phase What: An egg is released from the ovary into the fallopian tube. The dominant follicle in the ovary produces more and more estrogen as it grows larger. The dominant follicle reaches about 2 cm 0. When estrogen levels are high enough, they signal to the brain causing a dramatic increase in luteinizing hormone LH This spike is what causes ovulation release of the egg from the ovary to occur.
Ovulation usually happens about days before the start of the next period When: From ovulation until the start of the next period What: The sac that contained the egg produces estrogen and progesterone. Once ovulation occurs, the follicle that contained the egg transforms into something called a corpus luteum and begins to produce progesterone as well as estrogen 10, Progesterone levels peak about halfway through this phase The hormonal changes of the luteal phase are associated with common premenstrual symptoms that many people experience, such as mood changes, headaches, acne, bloating, and breast tenderness.
If an egg is fertilized, progesterone from the corpus luteum supports the early pregnancy If no fertilization occurs, the corpus luteum will start to break down between 9 and 11 days after ovulation This results in a drop in estrogen and progesterone levels, which causes menstruation.
The luteal phase typically lasts about 14 days, but between 9 and 16 days is common 4, When: From ovulation until the start of the next period What: The lining of the uterus releases or secretes chemicals that will either help an early pregnancy attach if an egg was fertilized, or help the lining break down and shed if no egg was fertilized.
During this phase, the endometrium prepares to either support a pregnancy or to break down for menstruation. Rising levels of progesterone cause the endometrium to stop thickening and to start preparing for the potential attachment of a fertilized egg.
The secretory phase gets its name because the endometrium is secreting producing and releasing many types of chemical messengers.
The most notable of these messengers are the prostaglandins , which are secreted by endometrial cells and cause changes to other cells nearby. The amounts of these prostaglandins rise after ovulation and reach their peak during menstruation 16, The cramping caused by this prostaglandin helps trigger the period. If pregnancy does not occur, the corpus luteum stops producing estrogen and progesterone.
The drop in hormones, along with the effects of the prostaglandins, cause the blood vessels to constrict tighten and tissue of the endometrium to break down Tracking symptoms throughout your menstrual cycle in Clue can help you feel more in control by helping you notice patterns and anticipate changes.

The first day of your menses — or period — is day 1 of your cycle and the start of the follicular phase.
Stages of the Menstrual Cycle
Menstruation is also known by the terms menses, menstrual period, cycle or period. The menstrual blood—which is partly blood and partly tissue from the inside of the uterus—flows from the uterus through the cervix and out of the body through the vagina. A menstrual cycle is considered to begin on the first day of a period. The average cycle is 28 days long; however, a cycle can range in length from 21 days to about 35 days. The steps in the menstrual cycle are triggered by the rise and fall of chemicals in the body called hormones. The pituitary gland in the brain and the ovaries in the female reproductive tract manufacture and release certain hormones at certain times during the menstrual cycle that cause the organs of the reproductive tract to respond in certain ways. The specific events that occur during the menstrual cycle can be described as follows:. Girls start menstruating at the average age of However, girls can begin menstruating as early as 8 years of age or as late as 16 years of age.

This series of hormone-driven events is called the menstrual cycle. During each menstrual cycle, an egg develops and is released from the ovaries. The lining of the uterus builds up. Then the cycle starts again. The menstrual phase is the first stage of the menstrual cycle. The thickened lining of your uterus, which would support a pregnancy, is no longer needed, so it sheds through your vagina.
With each cycle your body prepares the lining of your uterus to create the ideal environment for a possible pregnancy. Your menstrual cycle is the time between one period and the next. Every month there is a complex interaction between the pituitary gland in the brain, the ovaries and the uterus or womb. Messages and hormones are being passed around the body to prepare it for a possible pregnancy. An egg is produced, the lining of the uterus thickens up, hormones prepare the vagina and the cervix to accept and support sperm.
