Is It Normal, and What Does It Mean?

While a short period could be an early sign of pregnancy, there are many other possible causes, including lifestyle factors, birth control, or a medical condition.

The length of your period can fluctuate depending on many different factors. If your period suddenly becomes much shorter, though, it’s normal to be concerned.

Read on to learn more about what could cause your period to only last a day or two.

A normal menstrual cycle happens about once every 28 days, but this often varies. Some women have periods every 21 days, while others have periods that are 35 days apart.

When it comes to periods, every woman is different. Most women have periods that last around three to five days each month. But a period that lasts only two days, or goes on for seven days, is also considered normal.

If your period typically lasts several days and suddenly becomes much shorter, it could be due to a variety of causes.

Pregnancy may be the reason for a “period” that lasts only one or two days.

When a fertilized egg attaches to the lining of the uterus, implantation bleeding can happen.

This type of bleeding is usually lighter than a regular period. It most often lasts about 24 to 48 hours. It’s typically light pink to dark brown in color.

Implantation bleeding usually occurs about 10 to 14 days after conception. Not all pregnant women will experience it, though. According to the American College of Obstetricians and Gynecologists, implantation bleeding only happens in about 15 to 25 percent of pregnancies.

An ectopic pregnancy happens when a fertilized egg attaches to the fallopian tubes, ovary, or cervix instead of the uterus. It’s commonly called a tubal pregnancy.

One of the first signs of an ectopic pregnancy is vaginal bleeding along with pelvic pain.

If a fertilized egg keeps growing in the fallopian tube, it can cause the tube to rupture. That can lead to heavy bleeding inside the abdomen.

Seek medical help right away if you experience symptoms of an ectopic pregnancy, such as:

• severe abdominal or pelvic pain, usually on one side
• fainting or dizziness
• abnormal vaginal bleeding
• rectal pressure

A miscarriage can cause bleeding that may be mistaken for a period. Many women may be unaware they’re having a miscarriage since they might not have known they were pregnant to begin with.

The bleeding may be a light spotting or a heavy flow. The length and amount of bleeding will depend on the length of the pregnancy.

Other symptoms of miscarriage include:

• cramping
• abdominal or pelvic pain
• back pain

Breastfeeding can cause a delayed, lighter, or shortened period.

Prolactin, a hormone that helps make breast milk, also prevents menstruation from occurring.

Most women who breastfeed will resume their periods around 9 to 18 months after their baby is born.

Hormonal birth control pills or shots as well as intrauterine devices (IUDs) can cause shorter and lighter menstrual cycles.

The hormones in birth control pills can thin out the lining of the uterus. This can lighten and shorten your period. According to the Cleveland Clinic, women who take progestin-only pills may bleed between their periods.

Other medicines that may affect the frequency, length, or flow of your period include:

• blood thinners
• antipsychotics or antidepressants
• steroids
• herbs, such as ginseng
• tamoxifen (a medicine used to treat certain types of breast cancer)

A lot of different lifestyle factors can affect the duration of your period, including changes to your daily routine.

Let’s take a closer look at some of the most common lifestyle changes that can cause changes to your period.

Stress

High levels of stress can affect your hormones. This, in turn, can affect your menstrual cycle.

If you experience severe stress, you might have irregular, shorter, or lighter periods than normal. Or you may not have a period at all.

Your periods will most likely return to normal once your stress levels go back down.

Significant weight loss

Losing a lot of weight may lead to irregular periods. Eating disorders, like anorexia nervosa or bulimia nervosa, can cause periods to stop altogether.

Excessive exercise

An extreme amount of physical activity can cause irregular periods or the absence of a period.

If you don’t balance the amount of energy you burn with adequate nutrition, your body won’t have enough energy to keep all your systems working. So, it will start to shift energy away from some functions, like reproduction.

As a result, the hypothalamus, a region in your brain, may slow down or stop the release of the hormones that control ovulation.

Some types of medical conditions may affect your monthly cycle, causing a shorter period than normal.

Thyroid disease

Thyroid disease causes your body to produce too much or too little thyroid hormone. This hormone plays a vital role in your menstrual cycle.

When your body doesn’t produce the right amount of this hormone, your periods can become irregular and sometimes shorter than usual.

Symptoms of thyroid disease can vary, depending on what the type of disorder you have. But the most common symptoms include:

• weight loss or gain
• trouble sleeping, or feeling very fatigued
• a faster or slower heart rate than normal

Polycystic ovary syndrome (PCOS)

With PCOS, your body produces more male hormones than normal. This type of hormonal imbalance can stop ovulation from happening.

As a result, you may have a much lighter and shorter period, or no period at all. Other symptoms of PCOS can include:

• excessive facial hair
• fatigue
• a deeper voice
• mood swings
• infertility

Pelvic inflammatory disease (PID)

PID is a type of infection that happens when bacteria enter the vagina and spread to the uterus and upper genital tract. This infection is usually transmitted through sexual contact.

PID may cause irregular periods, but they’re typically heavier, longer, or more painful.

Other conditions

Less common conditions that may cause irregular or shorter periods include:

• cervical stenosis, a narrowing of the passageway through the cervix
• premature ovarian failure (POF), also known as premature menopause
• Asherman syndrome, caused by scar tissue or adhesions inside the uterus or cervix
• anemia
• pituitary disorders
• uterine or cervical cancer

Young women going through puberty may have irregular periods for the first few years after they start menstruating.

Another time when periods may become irregular is during perimenopause. This occurs quite a few years before menopause.

According to the Cleveland Clinic, women can enter perimenopause 8 to 10 years ahead of menopause, meaning it could happen in your 30s or 40s.

During perimenopause, estrogen levels start to drop. This can cause irregular periods.

Bleeding for only a day or two may be a sign of pregnancy, but there are many other possible causes, too.

If you’re concerned about your shorter than usual period, make an appointment to see your doctor. They can help you figure out what’s triggering the change and start treatment, if needed.

Monthly 2 days. Worth a look

Comment from an expert
Gynecologist Anastasia Degteva

“There is no lower limit when determining the abundance of discharge. However, if the nature of menstruation has changed dramatically, then you should immediately take a pregnancy test and consult a doctor. Most often this is temporary and will go away on its own, but it is best to make sure that the change in cycle is not a symptom of the conditions described above. The doctor will conduct an examination, make an ultrasound of the uterus and appendages, sometimes additional tests are required.”

Most women’s periods usually last 3 to 7 days, with an average cycle of 28 days. However, every woman is different, and normal periods are periods that you regularly have. Therefore, if your period always lasts 2-3 days, then this is not a cause for concern – this is a kind of norm.

The length and profuseness of menstruation can vary depending on many life factors, but if such changes occur suddenly and abruptly, then it is quite normal to worry about it.

It is very important to keep track of your cycle and note changes, if any. Most cycle failures are caused by harmless causes, but there are those that are associated with pathology.

Possible physiological causes of short periods:

Pregnancy and lactation

Short bleeding, which is similar to menstruation, can occur as a result of the attachment of a fertilized egg to the uterus and is called implantation bleeding. It occurs approximately 10-14 days after fertilization, occurs in 15-25% of pregnant women. This bleeding usually lasts 1-2 days and is less heavy than normal menstruation. The blood is usually light pink in color or vice versa dark brown.

When breastfeeding, periods may not return for several months after childbirth and may initially be shorter or longer than usual.

Age characteristics

In different periods of life, the menstrual cycle may change due to changes in the hormonal background: first of all, this applies to puberty and perimenopause.

During puberty, hormone levels begin to change within a month and it may take several years to establish a regular cycle. During this period, the duration of menstruation and the length of the cycle may vary.

During premenopause, the body prepares for its last menstrual cycle. Hormone production is reduced and a typical symptom is an irregular cycle.

Stress and excessive physical activity

If you spend more calories than you take in for a long time, your body can enter starvation mode, in which the calories consumed are spent on critical functions at the expense of others, such as the production of reproductive hormones.

Taking hormonal contraceptives or changing them

Hormonal contraceptives, including coils and shots, may cause short or less heavy periods and cause some bleeding in the middle of a cycle. The same features and intrauterine devices.

Taking medicines, herbs or dietary supplements

In addition to OCs, other medications taken may also affect periods. For example, antidepressants, thyroid medications, steroids, certain herbs (such as ginseng), and many cancer medications can shorten periods.

Short periods as symptoms of pathological conditions

Unfortunately, short periods can also be associated with many health problems that require medical attention.

Miscarriage

Miscarriage is a spontaneous termination of pregnancy that results in the loss of embryonic tissue or the fetus. A significant proportion of miscarriages occur in the early stages, even before a woman realizes that she is pregnant. That is why they are often confused with menstruation. Other symptoms may also appear:

• Spotting or drops of blood

• Abdominal pain

• Atypical discharge (tissue, clots, fluids) from the vagina

Polycystic ovaries

In this condition, the body produces too many male hormones that suppress ovulation and because of this, menstruation becomes irregular or disappears altogether.

Other symptoms include:

• Acne

• Changing the timbre of the voice to the lower register (deeper, lower)

• Excessive and unusual pattern of hair growth, especially on the face

• Difficulties with conception

• Weight kit

Polycystic is not a condition requiring immediate treatment, but if you have these symptoms, the sooner you see a doctor, the sooner you can find treatment that minimizes the symptoms of this condition.

Thyroid disorders

Such disorders lead to excessive or insufficient production of thyroid hormones. Thyroid hormones also affect the menstrual cycle and can cause various disruptions, including causing short periods.

• Symptoms depend on the type of disorder but may include the following:

• Decreased or elevated heart rate

• Abundant or scanty menses

• Weight gain or loss

• Drowsiness or insomnia

• Mood swings

These are the main pathological causes of short and scanty periods, but sometimes they can be associated with much more dangerous health conditions and diseases

Asherman’s syndrome

In this rare health condition, fibrous tissue grows in the uterus, which is characteristic of scars. The growth of fibrous tissue in the uterus can cause cycle failures or even their skipping. This rare condition most often occurs in women who have experienced surgery, miscarriage, and uterine cleansing. Since bleeding can only occur in healthy areas of the uterus, the most common symptom is scanty periods or even amenorrhea.

Other symptoms:

Sheehan syndrome

Sheehan’s syndrome is a complication after childbirth that occurs with a large loss of blood and critically low blood pressure. In countries with access to medicine, this complication is extremely rare. Sheehan’s syndrome leads to insufficient production of pituitary hormones, which causes cycle delays and failures.

Other symptoms:

• Low blood pressure

• Weight set

• Increased fatigue

• Difficulties with breastfeeding

• No growth of pubic hair

Cervical stenosis

Cervical stenosis is a rare condition in which the cervix is ​​abnormally narrowed. It usually develops as a complication after surgery. With this narrowing of the cervix, the menstrual flow cannot flow normally, causing delayed periods and abdominal pain.

Premature ovarian failure syndrome

Premature ovarian failure or failure syndrome occurs when the ovaries stop functioning normally before the age of 40, also called early menopause. If the ovaries are not working properly, they will not be able to produce the normal amount of estrogen and release an egg each month, which can lead to cycle delays and failures.

Other symptoms may include:

• Amenorrhea (absence of menstruation) or irregular cycle

• Sudden feeling of heat, flushes

• Infertility

• Vaginal dryness, insufficient lubrication

When should I see a doctor?

If you are pregnant or suspect you are pregnant and you experience unexpected bleeding, you should call an ambulance immediately.

In other cases, it makes sense to first look at the dynamics and consult a doctor if there are oddities in the next one or two cycles. Be sure to keep track of your cycle and unusual changes, if any (such as drowsiness, fast or slow heart rate, weight loss or gain, unusual hair growth, acne, etc.). It is convenient to do this in

cycle tracker app.

All of this information can help your doctor make a diagnosis.

when to go to the doctor

Have you noticed that your cycle has changed and now your periods are not 5-7 days, as it was before, but only three or even two? On the one hand, it’s nice that menstruation has ceased to be long and causes inconvenience for only three days instead of a week. On the other hand, if this happened without any effort on your part, then this is a reason to pay attention to the changes and consult a doctor if everything is fine.

Doctors believe that it is worth worrying if the intensity and duration of menstruation suddenly changes, although it had previously remained constant for a long time.

The normal cycle length is between 21 and 35 days – each of these options is perfectly normal. But if your cycle is 28 days, then its decrease to 21 or a sudden lengthening to 35 is a moment that you need to pay attention to. Such a fluctuation may not be associated with any pathology, but it is better to know that nothing serious is happening to you.

The discharge itself on average lasts from 5 to 7 days, but in some women it almost always lasts no more than three – this is also a variant of the norm. This parameter is influenced by our hormonal background, which is determined not only by external, but also by internal – hereditary – factors.

But, we repeat, in some situations, the duration of menstruation can unexpectedly decrease for you by as much as two times, for example, from six days to three.

You are using hormonal contraception

Contraceptive pills, spiral and other means of preventing pregnancy affect the production of sex hormones. In addition to the contraceptive effect, their intake also affects the duration of the cycle. Your periods may become shorter, less intense, and less painful. In some cases, they disappear altogether, turning into meager spotting.

You are taking medication

Medicines that at first glance have nothing to do with the cycle can affect the duration of menstruation. Among them are non-steroidal anti-inflammatory drugs (NSAIDs), drugs that are prescribed to reduce fever, fight pain and inflammation. Among them are popular antipyretics and analgesics that can be purchased without a prescription. In addition, antidepressants, drugs for the thyroid gland may have a similar effect.

If you have started taking these medications and notice changes in your cycle, it is best to consult your doctor to know exactly what is causing it.

This is premature ovarian failure

After 40 years, the ovaries begin to age – and this is normal. They produce less estrogen and ovulation becomes less frequent. This also affects the cycle – menstruation becomes less regular, and their duration changes.

However, it happens at a younger age. If this condition is observed before the age of 40, then doctors talk about premature ovarian exhaustion. In every hundredth woman, it occurs in the period from 30 to 39years, and every thousandth – at the age of 15 to 29 years. An unexpected shortening of menstruation or their complete stop without pregnancy is a reason for examination by a doctor.

You have adhesions

The condition in which adhesions form in the uterus is called Asherman’s syndrome. It does not occur very often, but it can develop in cases where a woman had to go through medical interventions that were required, for example, to treat gynecological diseases. If the inner surface of the uterus is injured, the epithelium is replaced by connective tissue and adhesions may form.

The appearance of intrauterine adhesions leads to a shortening of the cycle or even the complete disappearance of menstruation.
