8 Reasons Why You’re Getting Your Period Twice in One Month
Many factors can cause your period to come more often than usual. These include natural changes in hormone levels, missing a birth control pill, and lifestyle factors like being overweight or stressed.
Having your period twice in one month might also indicate a medical condition that requires treatment.
1. Normal menstrual cycle variations
A typical menstrual cycle lasts between 21 to 35 days. However, it’s not unusual for women to experience shorter cycles, particularly in adolescence or as they approach menopause.
According to the American College of Obstetricians and Gynecologists (ACOG), a shorter cycle can mean that a woman has two periods in one calendar month.
2. Hormonal imbalances
Hormonal imbalances are a common cause of irregular periods. Fluctuations in hormones like estrogen and progesterone can lead to more frequent bleeding.
Dr. Jennifer Wu, an OB-GYN at Lenox Hill Hospital in New York City, notes that stress, weight changes, and thyroid issues can disrupt hormone levels, potentially causing two periods in one month.
3. Polycystic Ovary Syndrome (PCOS)
PCOS is a condition that affects hormone levels, often leading to irregular menstrual cycles. Women with PCOS may experience cycles that are either too frequent or too infrequent. The Mayo Clinic highlights that irregular periods are one of the hallmark symptoms of PCOS.
4. Uterine fibroids
Uterine fibroids are noncancerous growths in the uterus that can cause heavy or prolonged menstrual bleeding. According to the National Institutes of Health (NIH), fibroids can disrupt the normal menstrual cycle, leading to bleeding between periods or more frequent periods.
5. Birth control
Hormonal contraceptives, such as birth control pills, patches, or intrauterine devices (IUDs), can affect menstrual regularity. Some women may experience breakthrough bleeding or spotting, which might be mistaken for a second period.
6. Infections
Pelvic inflammatory disease (PID) or sexually transmitted infections (STIs) can cause inflammation and irritation of the reproductive organs, leading to irregular bleeding.
The Centers for Disease Control and Prevention (CDC) advises that women experiencing unusual bleeding should consult a healthcare provider to rule out infections.
7. Perimenopause
Perimenopause is the transitional phase before menopause when a woman’s hormone levels begin to fluctuate. During this time, menstrual cycles can become irregular.
Dr. Mary Jane Minkin, a clinical professor of obstetrics and gynecology at Yale University, explains that perimenopausal women often experience changes in cycle length and frequency.
8. Thyroid disorders
The thyroid gland regulates many bodily functions, including menstrual cycles. Both hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid) can cause menstrual irregularities.
The American Thyroid Association emphasizes the importance of thyroid health in maintaining regular menstrual cycles.
When to See a Doctor
If you experience two periods in one month consistently, it’s best to seek medical advice. Persistent irregular bleeding can indicate underlying health issues that require treatment. A healthcare provider can perform tests to determine the cause and suggest appropriate treatment options.
