Why do I have 2 menstrual cycles per month?

It is not normal to have two menstrual cycles per month. A typical menstrual cycle lasts between 21 and 35 days, with the average cycle length being 28 days. However, some women may experience occasional variations in their cycle length.

If you are experiencing two menstrual cycles per month, there may be an underlying medical condition causing this irregularity. Some possible causes of frequent menstrual cycles include:

- Hormonal imbalances: Conditions such as polycystic ovary syndrome (PCOS) and thyroid disorders can affect the balance of hormones in the body, leading to irregular menstrual cycles.

- Uterine abnormalities: Certain abnormalities of the uterus, such as fibroids or polyps, can cause heavy or irregular menstrual bleeding.

- Infection or inflammation: Pelvic inflammatory disease (PID) and other infections of the reproductive organs can cause abnormal bleeding.

- Stress: Chronic stress can affect hormone levels and disrupt the menstrual cycle.

- Certain medications: Some medications, such as birth control pills and certain hormone replacement therapies, can cause changes in menstrual cycle patterns.

If you are experiencing two menstrual cycles per month, it's important to see a doctor for evaluation to determine the cause and receive appropriate treatment.
