The 10 Common Clear Reasons for a Missed Period

A missed period or even a delayed one is a common concern for all women. You have probably asked yourself this question before “why is my period late?”. You get so worried and scared to the point of even googling on your phone or computer. Some women even feel shy or embarrassed to talk to their mates or friends simply because they think they will be told they are pregnant! Something no woman wants especially if they are underaged, still in school, or not married yet. You are not alone. Many women out there go through this every day.

When you miss a period, the first thing that comes to your mind is pregnancy, especially if you are in a physically romantic relationship. I want to tell you that a missed period does not necessarily mean that you are pregnant. There are several other reasons for a missed or delayed period other than that.


You may have missed your period because you are stressed, exercising excessively, have low body weight, are going through menopause, or are pregnant. Other factors include being overweight, illnesses, birth control, hormonal imbalances, PCOS, or thyroid issues.

This article will take you through all of the possible reasons for a missed or delayed period. And most importantly, what to do if you do not get your period.

Let’s get started.

Reasons for a Missed Period

1. Pregnancy.

The most common cause of a missed period is pregnancy. That is, if you did not use birth control and have had unprotected sex. You are pregnant if you have not had your period in a while and have had unprotected intercourse.

Do not make any assumptions; instead, purchase a home urine pregnancy kit from a nearby chemist or store. You will know if you are pregnant or not after you receive your results. If the test is positive, contact or see your healthcare practitioner to set up your first prenatal appointment.

If you did not have sex and your period is missing, it could be due to a variety of other factors such as stress or underlying ailments, which we will go over one by one below.



  • Examine yourself for pregnancy symptoms.
  • Take a urine pregnancy test kit to be sure.
  • Always use a condom if you don’t want to get pregnant yet.
  • Take note of your cycle. Know yourself.
  • Abstain.

2. Stress.

Gonadotrophin-releasing hormone, a hormone that governs ovulation and the menstrual cycle, is disrupted by high-stress levels. Your body can stay in a switch-mode if you are under a lot of mental or even physical stress, which can cause you to cease ovulating momentarily.

Lack of ovulation might cause your period to be delayed because you will not have a period if you have not experienced ovulation. Stress can lead to illness or unexpected weight gain or loss over time, all of which can disrupt your cycle.

How to handle stress causing a missed period


  • Practice relaxation techniques.
  • Talk to someone you trust about your problems.
  • Visit a counselor.
  • Try some workouts or yoga.
  • Lifestyle changes.

3. Excessive exercise.

Excessive activity could be another reason for a missed period. Especially if you have only recently begun exercising and your body is still adjusting to the changes. The menstrual cycle is influenced by exercise since it raises the metabolism.

Metabolism is in charge of sustaining chemical reactions in the body, such as menstruation. Activity-induced amenorrhea occurs when you miss your periods as a result of strenuous exercise. A female athlete triad is a severe form of exercise-induced amenorrhea. If your periods do not arrive as a result of this, do not rejoice because exercise-induced amenorrhea has major long-term health repercussions.

While at the gym, do not exercise with too heavy weights. Consider smaller weights.



4. Birth control.

Birth control

The pill and emergency contraception are two different types of birth control. Depending on the birth control technique you use, periods might be longer, shorter, heavier, or lighter. The pill can influence your menstrual cycle because it operates by delivering different hormones into your system.

Birth control prevents ovulation, thins the uterine lining, prevents fertilized eggs from implanting, and thickens the cervical mucus, preventing sperm from reaching the egg. The truth is that each person is unique, and drug effects are not always predictable. If a person begins taking a new drug for the first time, the body may need time to acclimatize, resulting in a missed period.


  • If the form of birth control you are using affects you, try a different one.
  • Talk to your doctor.
  • Use a condom.
  • Stop using birth control.

5. Low body weight.

Another reason for a missing period could be low body weight. Eating disorders or even stress might cause this.
Missed periods are common among underweight women. Being underweight or having a low body-fat ratio can cause reproductive hormone levels to drop to dangerously low levels, preventing ovulation and menstruation.

Rapid weight loss can also put a strain on the body. If a person is on an extremely low-calorie diet, a shortage of calories can impede the release of hormones necessary for ovulation. Everything you do has consequences, so before restricting your body’s essential nutrients in the name of being on a diet, consider the consequences.


  • Eat healthily.
  • Make wise decisions when it comes to a balanced diet.
  • Seek medical help if you have eating disorders.


6. Menopause.

Because you are going through menopause, you can miss your period. The period preceding menopause is known as perimenopause. A change in your normal menstruation pattern is usually the first indicator of menopause. Some subtle and not-so-subtle changes in your body may occur during the menopausal transition.

You might have the following experiences: Irregular Periods. The length of time between periods may be longer or shorter as ovulation becomes more unpredictable, your flow may be light to heavy, and you may skip some cycles.

7. Being overweight.

Another possibility for a missing period could be your weight. Obesity might also disrupt your menstrual cycle.
If you are overweight, your body may create too much estrogen, a hormone that helps women manage their reproductive systems. Excess estrogen can influence the frequency of your periods and even cause them to cease.

Menstrual periods are sometimes disrupted by being significantly underweight. When the body is deficient in fat and other nutrients, it is unable to generate hormones as efficiently as it should. Rapid weight loss or gain due to sickness, medicine, or dietary changes might cause hormone production or release to be disrupted. As a result, you might miss one or more periods.


  • Work on your weight.
  • Eat healthily.

8. Illnesses

You may miss a period due to an ailment that you are unaware of. Certain illnesses might disrupt periods.
The polycystic ovarian syndrome is the most common. Hormone production can be affected by conditions such as PCOS or hypothyroidism. The hormonal changes associated with both illnesses might cause uterine lining changes, resulting in irregular periods.

These illnesses include:

  • Diseases of the adrenal gland.
  • Diabetes.
  • Liver dysfunction.
  • Ovarian cysts
  • Thyroid disease.
  • Polycystic ovary syndrome (PCOS).
  • Pituitary tumors.



9. Some medical conditions.

You may miss a period due to some medical conditions. Acute illnesses like pneumonia, heart attacks, kidney failure, and meningitis can cause rapid weight loss, nutritional deprivation, and hormone disruption. Missing a period can also occur as a result of certain situations.


  • Visit the doctor.
  • Go for various tests to ascertain the problem.

10. Medication

You may miss your menstruation if you use certain drugs. Aside from birth control, Druet lists thyroid and steroid drugs as medications that may cause your period to be delayed because they affect the hormones that control your cycle.
Antidepressants, antipsychotics, thyroid drugs, anticonvulsants, and some chemotherapy medications can all cause your period to skip or be late.



Apart from pregnancy, the post has taught you that there are a variety of reasons for a missed or delayed period. This is quite natural and has most likely happened to you or a friend. Take a peek at a woman’s phone and her Google search history and you will see what I am talking about.
