3 Day Period: What You Need To Know About Short Periods

Have you recently experienced a 3-day period? The average menstrual cycle happens every 28 days, although the normal range is between 21 to 40 days. It’s common for menstrual cycles to last for a full week. However, if they’re shorter then a woman might wonder whether or not it’s “normal.” Health experts explain that the length of the periods isn’t as significant as whether or not the menstrual cycles are similar month after month. If that happens then it’s the menstrual cycle that could be considered “normal.” There are also various factors that could trigger short menstrual cycles including teenagers starting puberty.

It’s important to separate fact from fiction in terms of various factors related to menstrual cycles. For example, in 1920, Hungarian-American doctor Béla Schick wrongly suggested a theory that toxins are produced during menstruation. This was based on observing that certain flowers a nurse handled wilted sooner than others. However, in recent decades many old-school myths about menstrual cycles have been disproven. Menstrual hygiene has also improved over the decades, which has also benefited women’s health. That includes the invention of the “Tampax” tampon nearly a century ago in 1929. Today there are several types available including eco-friendly organic tampons.

What Exactly Is the Menstrual Cycle?

When teenage girls go through puberty it involves their bodies getting ready for a possible pregnancy. Periods are part of the menstrual cycle, which involves regular hormone cycling that happens within the female reproductive system. This process allows pregnancy to be possible.

Menstruation/period is the time when a woman discharges substances including blood from the uterus’ lining. This happens about once every month beginning with puberty. It ends during menstruation, which includes 12 consecutive months of no menstrual cycles. The exception is throughout pregnancy.

The average menstrual cycle lasts from 3 to 5 days. However, sometimes it lasts for a full week. There are various signs/symptoms of menstruation including:

  • Acne
  • Mood changes
  • Bloating
  • tiredness
  • Abdominal pain
  • Breast soreness
  • Headache
  • Food cravings

The menstrual cycle is a hormone-related cycle. The first day of the cycle is Day 1, which involves the period starting. Meanwhile, the ovulation day is around Day 14. In the case, the egg doesn’t get fertilized the woman’s hormone levels drop. Then around Day 25, the egg starts to dissolve and the cycle starts over again. The menstrual cycle ends around Day 30.

Day 1 of the cycle is when menstruation starts. It usually ends around Day 3 or Day 5 of the menstrual cycle. In some situations, it lasts until Day 7.

The average age a female starts her first menstrual cycle is 12. However, it can be as high as 15 years old. The periods continue until around the ages of 45 to 55. In the USA the average age of menopause is 51 years old.

During the menstrual cycle, there are various treatments for menstrual pain. It’s based on the cause of the pain. Some treatments include NSAIDs like Advil and other over-the-counter (OTC) medicines that are non-prescription. They’re used to treat pain/cramping. It’s also important to use good menstrual hygiene during the menstrual cycle.

3-day Period: What You Need to Know

If you have a short period it might seem helpful. However, many women are concerned that it’s a sign that something is wrong.

Going through a monthly period can be difficult. There are various issues to deal with including pre-menstrual syndrome (PMS) and others. Sometimes women have few symptoms due to naturally short/light menstrual cycles. This helps to explain that a short period is normal for some women.

However, it’s important to determine whether a short period is regular or irregular. In the case it’s light/irregular it could be a sign of various issues like menopause, pregnancy, or medical conditions.

One key issue to consider is that “normal” menstruation is different for different women. The length usually ranges from 3 to 7 days. Meanwhile, the total menstrual cycle’s length can range from 21 days to 35 days.

A 3-day menstrual cycle might seem to be short. However, it can be normal if it’s the regular length of your menstrual cycle. In many cases, the short menstrual cycle is normal and is part of a regular period. It’s important to talk to your doctor about the issue if you think there might be medical issues.

Doctors explain that if a woman’s monthly period is X days month after month then it’s her regular pattern. However, if the number of days ranges greatly from month to month then it’s a sign of something else, including health issues.

What’s most important is not to panic if you have short menstrual cycles. It’s important to contact your doctor. He/She can then order tests to determine the cause of the situation. In some situations, it’s due to normally short menstrual cycles. In other situations, it might be caused by something else that requires more tests.

Short Menstrual Cycles: Most Common Causes

There are various causes of short menstrual periods:


If the body doesn’t produce enough estrogen during menstruation cycles the “endometrium” will be thinner. This results in shorter menstrual periods including three days.

It’s common for older women nearing menopause to have short/irregular menstrual cycles. This is related to the ovaries not producing the hormones estrogen/progesterone. This prevents the forming of the endometrium.

Meanwhile, girls going through puberty also produce less estrogen. That’s because the hormone levels haven’t balanced out yet.

Birth control

More specifically, the particular method used could affect the length of the menstrual cycle. Some methods slow down the uterine lining’s growth. This reduces flow levels. It’s considered a benefit of some kinds of birth control yet it could also shorten the length of monthly periods.

Health Conditions

There are various health conditions like PCOS, thyroid problems, pituitary gland, and hypothalamus (brain) are some of the various causes of short menstrual cycles. It’s important to have these issues checked to determine if you have them.


Another cause is an “ectopic pregnancy.” This happens when a fertilized egg doesn’t sit inside the uterus and instead sits in the fallopian tube. When that happens, doctors rule out pregnancy first if the period doesn’t happen on time.

Stress Levels

A high-stress life can affect hormone levels by boosting the stress hormone cortisol. It can also cause other hormone-related issues. In fact, stress can cause a wide range of health issues. So it’s important to deal with high-stress ASAP.

Diet And Exercise

There are various issues related to diet and exercise that might affect the length of your periods. They include eating disorders and low weight. These issues should be addressed to find the main cause, although they could affect your period durations.

Another factor is too much exercise. We usually think of a lack of exercise as a health hazard. However, over-exercising can also cause health issues including muscle fatigue and possibly a 3-day period.
