    Hormonal imbalance is a common factor that causes irregularities in this phase of menstruation. This can be due to thyroid issues, Perimenopause, or Polycystic Ovary Syndrome (PCOS).

    According to a study, excessive or low thyroid affects hormone levels and can lead to irregularities in one’s periods. This may sometimes cause spotting before periods and result in 2 periods.

    In PCOS, women experience hormonal imbalances due to ovarian cysts. This can often lead to irregular ovulation. As a result, women experience irregular periods during PCOS, causing more than one period in a month.

    Hormone levels can also fluctuate during Perimenopause (the transition phase before Menopause), resulting in unpredictable ovulation patterns. This makes menstrual irregularity one of the symptoms of Perimenopause.

    Uterine or Cervical Issues

    Most women with uterine or cervical issues may experience more than one period in a month. Women who have Uterine Fibroids (non-cancerous growths in the uterus) may also experience this symptom.

    In the case of Uterine Fibroids, women may experience bleeding between periods and frequent periods. It is also similar in women who have Cervical or Uterine Polyps.

    One of the most common symptoms of Polyps is abnormal uterine bleeding. It is often followed by period cramps and pelvic pain.

    In case of a condition like Endometriosis, an individual may face severe pain and irregular menstrual cycles. 

    Polyps are non-cancerous growths that form on the lining of organs like the uterus or colon. It leads to irregular bleeding or other symptoms depending on their location.
    Endometriosis is where tissue like the uterine lining grows outside the uterus. It can cause pain, irregular periods, and sometimes infertility.

    Lifestyle Factors

    Several lifestyle factors can influence menstrual regularity and lead to two periods in a month. 

    Hormonal fluctuations can occur in individuals under severe stress. These fluctuations can cause irregular ovulation and abnormal periods. Women who are obese may also experience two periods in one month. 

    The fat tissues in obese women often lead to more than enough Estrogen in the body, which causes irregularities during menstruation. In some cases, excessive exercise may also lead to this symptom due to physical stress.

    Other Medical Conditions

    Apart from the above-mentioned causes, some individuals can experience frequent periods due to other medical conditions. These are usually infections that change menstrual bleeding patterns.

    Infections, like STIs or PID, can cause inflammation and irritation of the reproductive organs. These irritations usually change the bleeding pattern, leading to multiple periods in a month. 

    If you are using any anticoagulants or corticosteroids and experiencing more than one period in a month, it is best to consult your doctor immediately. Overusing these medications can reduce your body’s ability to regulate menstrual bleeding, resulting in irregular cycles.

    Treatments For Two Periods in a Month

    Since the answer to the question, “Is it normal to have two periods in one month?” is no, women often look for effective treatment options. 

    Experts often suggest maintaining a healthy diet and avoiding excessive exercise to prevent irregular periods. They may also prescribe hormonal birth control pills to stabilize the menstrual cycle.

    Some women may benefit from using iron supplements since they can reduce Anemia caused by more than one period. Doctors may suggest thyroid hormone replacement therapy or antibiotics in cases of thyroid disorders or infections. 

    Women with cervical or uterine abnormalities may have to undergo surgical procedures for a complete cure. In order to reduce pain in these cases, one may also opt for Non-steroidal anti-inflammatory drugs (NSAIDs).


    Two periods in one month are abnormal and can indicate underlying serious conditions. Usually, most women experience it due to hormonal disorders of the thyroid or due to PCOS and Perimenopause.

    Others may face it due to uterine or cervical structural problems. Another common factor indicates a bad lifestyle is the underlying cause of these symptoms. 

    Additionally, medical conditions like PID or STIs and certain medications may also cause this irregularity. As a popular treatment, doctors usually suggest maintaining a healthy lifestyle to avoid two monthly periods. 

    They may also suggest hormonal birth control pills or medications based on the underlying cause. Hence, it is always best to consult an expert for a proper diagnosis and appropriate treatment.
