Important Monthly Cycle Hormones
The reproductive system is influenced by hormones that are regulated by the hypothalamus and the gonadotropin-releasing hormone . GnRH causes the cells in the frontal part of the pituitary gland to produce two types of hormones.
The first hormone is follicle-stimulating hormone , and the other is luteinizing hormone . These hormones travel all the way to the ovaries, where they influence estrogen and progesterone levels and help the follicles inside the ovaries mature.
Some of the matured follicles will eventually release eggs, which travel down the uterine tubes, where they can be fertilized before moving to the uterus. The complex hormone interaction that makes this possible is called the hypothalamic-pituitary-ovarian axis.
At the end of a cycle right before menstruation, estrogen and progesterone levels drop, causing an increase of FSH and GnRH levels.
All the hormones involved in the hypothalamic-pituitary-ovarian axis rise in one phase of the menstrual cycle and drop in the other. All of these fluctuations affect ovulation and can cause symptoms like acne, negative mood, headache, weight gain, bloating, and appetite changes.
Now lets take a look at how hormone levels change during the cycle stages.
How The Menstrual Phase Makes You Feel
The physical symptoms during this phase vary from woman to woman, though it typically includes bleeding, abdominal cramping, and bloating. Cramping ranges from light to very painful due to the presence of prostaglandin, a hormone-like compound that causes the uterus to spasm. However, if you’re experiencing heavy bleeding that lasts longer than a week, you should speak to your doctor. “Very heavy or extended bleeding could indicate the presence of fibroids or other disease states such as precancerous changes or symptoms of endometriosis,” says Bruce McLucas, M.D., OB/GYN, assistant clinical professor at the UCLA School of Medicine and founder of the Fibroid Treatment Collective. Menopause may also result in an irregular period, he adds.
According to Healthline, you may feel a bit fatigued during the bleeding phase, and it has to do with you guessed it hormones. “When your uterine lining isnt invaded by a fertilized egg, the hormones sustaining the environment arent needed anymore and the hormone levels plummet,” Dr. Molly OShea, M.D., Detroit-based pediatrician, told Good Housekeeping. “When this happens, your body goes from high alert to nothing hormonally and that shift causes other changes, too, and all of those changes are exhausting. Until your hormone levels increase again, you are really tired.”
What Happens To Hormones During The Menstrual Period
Your pituitary gland is the master gland that controls the hormone production between the ovaries and the brain during your menstrual cycle. It controls essentially the menstrual cycle, because if the balance of hormones is completely out of alignment, no period will occur.
An example of this is seen in those who have anorexia. Their hormone production of both estrogen and progesterone is so low that they dont have periods. The pituitary gland shuts them off because the body would be unable to support a pregnancy.
Your menstrual cycle is about 28 days for most women. However, it can be as little as 24 days and as most as 35 days. If your girlfriends are menstruating at the same time but you arent, amazingly, your body will start to sync to the same rhythm as your girlfriends.
On the first day of your period, your two female hormones estrogen and progesterone are low. This causes the pituitary to start producing follicle stimulating hormone or FSH for short. The purpose of the FSH is to make an egg located in the ovary start to mature.
This egg is going to need more estrogen to mature in the uterus so estrogen levels start to rise. It will take about 12-14 days for the egg to mature. Then the high levels cause the pituitary gland to release luteinizing hormone which miraculously releases the egg from the follicle.

How To Balance Hormones Causing Irregular Periods
While there are lifestyle changes you can make that can help regulate your hormones, its best to see a doctor if youre having symptoms of hormone imbalance or if your periods are irregular.
They will be able to monitor hormone levels and make sure theyre where they need to be. They can also determine whether or not treatments are working.
Depending on the underlying cause of the hormone imbalance or which hormones are irregular, other treatments might also be used.
How To Feel Your Best During This Phase
If you’re extra tired during your period, take it easy and rest more than you usually do. Erika Schwartz, M.D., an internist and author of The Hormone Solution, recommends using heating pads for aches and discomfort as well as low doses of Advil, Aleve, or Tylenol with codeine if pain is persistent. And avoid caffeine, she says, as it constricts blood vessels and increases tension.

How Your Energy Levels Change On Your Menstrual Cycle
Carly Snyder, MD is a reproductive and perinatal psychiatrist who combines traditional psychiatry with integrative medicine-based treatments.
Mood changes and discomfort are common before and during a person’s menstrual cycle. You’ve likely learned what to expect from your body during menstruation, but hormonal fluctuations affect your body throughout the entire month.
Your mood and energy levels consistently change due to hormonal shifts during your cycle. This is why you may find you’re more productive during certain weeks than others.
Let’s explore the sequence of events your body goes through each month and learn more about identifying these changes so you can maximize your mood and productivity during different points in your cycle.
The Luteal Phase Is Named For The Corpus Luteum The Corpus Luteum Produces Progesterone Which Ripens The Uterus Lining
Mood and hormones: Levels of oestrogen start to deplete, which can lead to lower moods, and you may feel low or snappy. On the positive side, some find a low mood is combined with a new-found desire for physical interaction.
Mind: Its worth reminding yourself that in a few days your oestrogen will start to rise, and it is likely that your mood will begin to shift in a positive direction.
Nutrition: As your brain looks for ways to boost energy it may send out messages to eat sugar. Due to rising progesterone and its effect on the gut, many women often feel bloated for some they could experience loose bowel movements while for others its constipation.
Exercise:How you treat your body as it moves toward the menstrual phase may affect how you experience your period: if you feel lethargic and achy, cut yourself some slack. Consider pilates or steady-state cardio.
Sleep: During this stage in your cycle levels of progesterone will increase, which, for many, can have a sedative effect and encourage a deeper, more restful sleep.
Good to know:Daily supplements of calcium, magnesium and vitamins D and B6 have been shown to mitigate cramps, also mood swings and food cravings. Drinking less caffeine in the luteal phase may also reduce PMS symptoms.

Week 3 Begins The Day After Ovulation And Lasts 8 Days : Progesterone Rises Estrogen And Testosterone Drop The First Half This Week Then Estrogen Rises Again
Your Week 3 is really a two-parter: During the first half, you can experience a pre-PMS phase. The symptoms are like a shorter, less intense version of premenstrual syndrome and may include irritability, fatigue and a down mood. Like PMS, this pre-PMS phase is also caused by plunging estrogen. While most women are aware that estrogen plunges once in their cyclein the six days before their periodnot many realize there are actually two estrogen dips every cycle .
Luckily, by the second half of your Week 3, estrogen rises again, putting a stop to any annoying pre-PMS symptoms youve experienced, which helps level out your mood.
Progesterone rises throughout your Week 3 and, as it does, it slows you down and makes you quieter, more cautious and a bit foggy and physically fatigued. Thats because progesterone is a sedating hormone. If youre sensitive to progesterone, this can be a cycle phase when you experience bouts of sadness or crying.
During your Week 3, progesterone has you craving favorite comfort foods that are high in fat and calories. Your appetite is also greater and youre hungrier more often, so you tend to eat more at meals and snack more frequently. All this is because your body thinks you might have gotten pregnant during ovulation, so progesterone wants you to eat enough for two.
What Is Toxic Shock Syndrome
Toxic shock syndrome is a rare but sometimes deadly condition caused by bacteria that make toxins or poisons. In 1980, 63 women died from TSS. A certain brand of super absorbency tampons was said to be the cause. These tampons were taken off the market.
Today, most cases of TSS are not caused by using tampons. But, you could be at risk for TSS if you use more absorbent tampons than you need for your bleeding or if you do not change your tampon often enough . Menstrual cups, cervical caps, sponges, or diaphragms may also increase your risk for TSS if they are left in place for too long . Remove sponges within 30 hours and cervical caps within 48 hours.9
If you have any symptoms of TSS, take out the tampon, menstrual cup, sponge, or diaphragm, and call 911 or go to the hospital right away.
Symptoms of TSS include:10
- Sudden high fever

Whats The Follicular Phase
A few days after the first day of your period, FSH and LH are released. These hormones prompt your ovaries to produce from 15-20 eggs, each housed in their own follicle. Right now, theyre growing and competing on the lead up to ovulation as – usually – only one egg will be released! Its a bit like Americas top model for eggs only the best make it down the fallopian tube catwalk.
As one follicle begins to dominate and outgrow the rest it starts pumping out oestrogen, reducing FSH. It also helps your uterine lining develop, ready for the possibility of a fertilised egg. You could also notice an increase in cervical fluid and vaginal lubrication as your body moves towards ovulation in the second week.
Phase : Ovulation Phase:
When: About halfway through the cycle, around day 13-15 .
What happens: The release of the egg from the ovary, mid-cycle. Oestrogen peaks just beforehand, and then drops shortly afterwards.
The dominant follicle in the ovary produces more oestrogen with its increase in size. It can usually reach up to about 2 cm but can also be up to 3 cm at its largest right before ovulation.
When oestrogen levels are high enough, they signal to the brain causing a dramatic increase in luteinizing hormone which in turn causes ovulation to occur.
Ovulation usually happens about 13-15 days before the start of the next period. During this phase, we are at our brightest, most energetic, with lots of motivation to get things done. Keep in mind that good nutrition during this phase is very important to fuel that energy
It is also worth noting that during this phase, an extremely common condition known as an ovarian cyst can form. Have a peek at our dedicated article to know more about it

How Your Menstrual Cycle Affects Your Behavior
Feeling moody? It could be your menstrual cycle. Find out how your hormones can impact your emotional health all month long.
When a task as simple as a trip to the supermarket becomes an emotional ordeal, Morgan Sheets knows that her period is just around the corner.
The 29-year-old from Indianapolis says that during some months, she notices her emotions becoming more unstable in the five days or so before she is due to start menstruating.
I begin feeling like everything in my life is wrong and that I’m leading the wrong life, says Sheets, a marketing director.
Little things like making decisions about groceries to buy or getting dressed in the morning become monumental, and I agonize over them. Sheets says she also becomes much more sensitive and cries more easily.
Sheets is just one of the many women who experience premenstrual syndrome, or PMS, a collection of unpleasant symptoms, such as anxiety and bloating, that typically occur one to two weeks before menstruation and might influence behavior through in the menstrual cycle.
An estimated 85 percent of women experience at least one symptom of PMS per month, the American College of Obstetricians and Gynecologists estimates.
While PMS and its related hormonal changes are often talked about and are even the subject of endless jokes on TV sitcoms, the truth is that the hormones in a womans body can influence her moods and actions throughout the month.

Hormones And Your Menstrual Cycle
Chioma Ndubisi, MD, is a board-certified OB/GYN who specializes in sexual and reproductive health in New York, New York.
Your menstrual cycle is controlled by hormone signals in the brain. Each month, your ovary will release an egg after the egg has matured. The egg enters into the fallopian tube and makes its way down to the uterus with hopes that a sperm will fertilize it. Your monthly menstrual cycle begins on the first day of your period and lasts until the first day of your next period.
