Having two periods in one month is not common and may indicate an underlying issue. Here are some possible causes of having two periods in one month:

• One-time anomaly: A person may occasionally have a shorter menstrual cycle that includes two periods in a month. Following this, their periods may return to their regular cycle.

• Young age: Irregular menstrual cycles are common in young people who have just started to have periods. People tend to have shorter or sometimes longer menstrual cycles during puberty, which may lead to them having two periods in one month. Hormone levels fluctuate significantly during puberty, and research suggests that a young person’s menstrual cycle can take around 6 years to become regular from the time they start having periods.

• Endometriosis: This is a condition where tissue that is similar to uterine tissue grows in other areas of the body. Endometriosis can cause abdominal pain, abnormal cramping, and irregular bleeding. Sometimes, bleeding can be heavy enough to seem like another period.

• Perimenopause: This is the phase that leads up to menopause, during which hormone levels fluctuate and periods may become irregular. Perimenopause can be an underlying cause of having two periods in one month.

• Thyroid problems: Hormonal imbalance or problems with ovulation caused by thyroid dysfunction can cause irregular vaginal bleeding.

• Uterine fibroids or cysts: These are noncancerous growths in the uterus that can cause heavy or prolonged bleeding.

• Stress, too much exercise, and weight changes: These can cause two periods in one month.

Its important to note that getting two periods in one month isnt always a cause for concern. For example, people with short menstrual cycles frequently have periods at the beginning and the end of a month. However, if youre familiar with your cycle and have noted recent changes, or if you just feel like youre bleeding more than you should be, its important to talk to your doctor. They can help get to the bottom of your issue, and if warranted, can help you balance your hormone levels and provide personalized treatment options.
