If you have missed your period and you are not pregnant, it is important to figure out what the cause could be. There are many reasons why you might have skipped your monthly cycle, and some of them are more serious than others.
In this article, we will discuss 10 of the most common reasons why women miss their periods other than pregnancy. So, without further ado, let’s get started!
1/10 – Stress
One of the most common reasons for missed periods is stress. When you are under a lot of stress, your body can go into “survival mode” and begin to shut down non-essential functions like your reproductive system. If you have been under a lot of stress lately, it might be the reason why you missed your period.
Stress can come from many sources, including work, school, relationships, and finances. If you have been feeling particularly stressed lately, try to take some time for yourself to relax and de-stress. There are also many natural methods that can help reduce stress levels, such as exercise, meditation, and aromatherapy.
2/10 – Polycystic Ovarian Syndrome (PCOS)
PCOS is a hormonal disorder that can cause missed or irregular periods, as well as other symptoms like weight gain, acne, and excess hair growth. If you have PCOS, your body produces high levels of the hormone testosterone, which can interfere with ovulation.
There is no cure for PCOS, but there are treatments that can help regulate your hormones and reduce symptoms.
If you think you might have PCOS, it’s important to see a doctor so they can diagnose and treat the condition.

3/10 – Extreme Exercise
If you’re working out excessively, you may miss your period due to what’s known as “amenorrhea.” This is when your body doesn’t produce enough of the hormone estrogen, which can disrupt your menstrual cycle.
If you think your extreme exercise habits may be causing you to miss your period, it’s important to talk to a doctor. They can determine if you have amenorrhea and recommend ways to help regulate your hormones.
4/10 – Weight Gain or Loss
Significant weight gain or loss can also disrupt your menstrual cycle. This is because your body fat percentage needs to be within a certain range for you to ovulate regularly.
If you’ve experienced sudden weight gain or loss and are missing your period, it’s important to see a doctor. They can help you manage your weight in a healthy way and get your hormones back on track.
5/10 – Certain Medications
Certain medications can interfere with your body’s ability to ovulate, which can lead to missed periods. These include some types of birth control, antipsychotics, and antidepressants.
If you’re taking any medication that could potentially cause amenorrhea, it’s important to talk to your doctor. They may be able to switch you to a different medication that won’t have the same effect.

6/10 – Irregular Sleep Patterns
Getting too little or too much sleep can throw off your whole system, including your menstrual cycle. Try to stick to a regular sleep schedule as much as possible and get at least seven hours of sleep each night.
If you’re having trouble sleeping, talk to your doctor. They may be able to prescribe medication or suggest other treatment options.
7/10 – Thyroid Problems
Your thyroid is a small, butterfly-shaped gland in your neck that produces hormones that regulate your metabolism. If it’s not working properly, it can cause irregular periods.
An underactive thyroid (hypothyroidism) is the most common type of thyroid problem and can often be treated with medication.
If you think you may have a thyroid problem, talk to your doctor. They can do a blood test to check your hormone levels and make a diagnosis.
8/10 – Changes in Birth Control
If you’ve recently started or stopped taking birth control, it can affect your hormone levels and cause you to miss a period.
It can also take a few months for your body to adjust after starting or stopping birth control. If you’re concerned about changes in your period, talk to your doctor. They can help you figure out if your birth control is the cause and whether you need to make any changes.

9/10 – Perimenopause
Perimenopause is the transition into menopause. It usually starts in your 40s, but it can start earlier or later.
During perimenopause, your ovaries make less estrogen. This can cause changes in your period, including missed periods.
If you’re in perimenopause and missing periods is a concern, talk to your doctor. They can help you manage your symptoms and figure out if menopause has started.
10/10 – Serious Health Problems
Rarely, missed periods can be a sign of a serious health problem, such as:
- Cancer
- Thyroid disorders
- Pituitary tumors
If you have any other symptoms along with missed periods, talk to your doctor. They can help you determine if there’s an underlying cause that needs to be treated.
Conclusion
If you’re experiencing any of the symptoms above and you’ve ruled out pregnancy, it might be time to visit your doctor for a check-up.
