An occasional early period usually doesn’t raise any issues. Each person has a unique menstrual cycle. The first day of your current period marks the beginning of the process, which finishes on the first day of your subsequent period.
The bleeding days vary from one person to another because a typical cycle can last between 21 and 39 days. The average person bleeds for two to seven days. But what sets off your period early?

There may be an underlying issue if your period usually lasts less than 21 days and causes you to bleed earlier.

What Sets Off Your Period Early?

Some of the causes are:


Between the ages of eight and thirteen, puberty usually starts. Reproductive hormones are a class of substances that control it. These hormones will impact your menstrual cycle throughout your childbearing years.

These hormones may be irregular during the first few years following your cycle. This indicates that the interval between your periods could be shorter or longer.

Puberty may also result in:

– Expanding breast tissue

– Hair growth in the groin area and armpits

– Acne

– Mood changes


The period before menopause is known as perimenopause. Usually starting in your mid-to-late-forties, it lasts for around four years.

Your hormone levels fluctuate significantly during this time, and you might not ovulate every month. You may menstruate earlier or later than usual as a result of this hence resulting in irregular periods.

In addition, perimenopause can lead to:

– The flow of periods that are heavier or lighter than usual

– Missing periods

– Dryness of the vagina

– Hot flashes

– Reluctance to sleep

– Irritability

Intensive workout

Intense exercise might cause irregular periods or even the complete cessation of your period. This condition is often linked to athletes who practice for several hours daily. It most often occurs in weight-restricted sports like ballet and gymnastics.

When you exercise, your periods change when you burn far more calories than you consume. Your body doesn’t create the necessary quantity of reproductive hormones to ovulate if you aren’t getting enough energy.

Weight fluctuations

Significant weight fluctuations are frequently linked to early, irregular, or skipped periods. Period irregularities sometimes accompany rapid weight reduction. Extreme dieting, gastric bypass surgery, or eating problems can cause this.

The body saves energy for vital bodily processes, like breathing, when it goes into hunger mode. Your cycle will become erratic when your body stops manufacturing reproductive hormones.


You face hormonal imbalances if you suffer from anxiety or have just been through a stressful experience.

Additional effects of stress include unexplained weight gain or loss and difficulty concentrating and sleeping.

Change in Routine

Your hormones may change due to modifications in your regular schedule, which could result in an early or late period. For instance, according to some studies, nurses and other individuals who work alternate day and night shifts frequently have irregular menstrual cycles. Similar consequences could result from a time zone change.

It may be caused by a change in your circadian rhythm, though researchers are unsure of the specific cause. The sleep hormone melatonin may then be affected by this.

Blood Thinners

Blood thinners (anticoagulants) may lengthen your period and cause heavy bleeding.

During your period, anticoagulants help to thin your uterine lining so it can pass through the vagina. Anticoagulant use may hasten this process and result in a heavier flow.

Hormonal Contraception

The hormones found in hormonal birth control directly impact menstruation and ovulation.

When you started taking birth control pills during your cycle and whether or not you took a week of placebos (reminder pills) will determine when your next period will start.

Along with what sets off your period early, hormonal birth control may cause you:

– Cramping

– Aching breasts

– Headaches

– Nausea

Emergency Birth Control

To lessen your chance of becoming pregnant following unprotected sex, you can use emergency contraception (EC tablet) or get a copper IUD implanted.

The hormones in EC tablets prevent ovulation from occurring as they should. They could result in an early or late onset of your period. Using them regularly causes period irregulations.

After having an IUD inserted by their doctor, patients frequently experience breakthrough bleeding. The uterus needs a few months to adjust to the IUD, during which the patient can experience daily or irregular bleeding.

The following are other effects that copper IUDs may have:

– Unpleasant menstruation cramps

– Back pain or cramping

– Several sexually transmitted diseases (STIs)

Chlamydia and gonorrhea are two STIs that are pretty prevalent. Usually, these bacterial infections don’t result in symptoms. When they occur, they are known to result in spotting between periods or discharge tainted with blood.

They could also result in sex pain, burning when urinating, and abdominal pain.

Polycystic Ovarian Syndrome (PCOS)

The leading cause of the common disorder PCOS is hormonal imbalance. One in ten females who are of childbearing age are affected by it.

Many people don’t become aware of their PCOS until they have trouble getting pregnant. Other effects include irregular periods, absent periods, and acne with too much facial or body hair and weight gain.

Endometriosis develops when endometrium-like tissue increases in organs other than the uterus, such as the ovaries, abdomen, and colon. It affects around 11% of American women between the ages of 15 and 44.

Severe menstrual pains and sudden bleeding are side effects of endometriosis along with persistent lower back ache discomfort after or during sex.

Thyroid Issues Are the Last of What Sets Off Your Period Early

One in eight women experienced thyroid problems.

When you have a thyroid issue, your body produces more or less thyroid hormone than is necessary. Your metabolism and menstrual cycle, among other bodily processes, depend on this hormone.

You may have different symptoms depending on whether your thyroid is underactive or hyperactive.

Along with early menstruation, you might encounter:

– Heavier or lighter flow of periods than average.

– Quicker or slower heart rate than usual.

– Sleeping problems.
