Your period can come early for several reasons, mostly related to changes or imbalances in hormone levels. Common causes include:
- Hormonal fluctuations during puberty or perimenopause when the body's reproductive hormones are changing.
- Stress, intense exercise, or changes in routine can affect hormone levels and cause your cycle to shift.
- Weight changes , either gain or loss, can influence your menstrual timing.
- Certain medications or supplements including birth control or blood thinners.
- Medical conditions such as polycystic ovary syndrome (PCOS), endometriosis, thyroid disorders, or diabetes can disrupt your cycle.
- Occasionally, lifestyle factors like diet changes or travel can also lead to early periods.
If your early period is a one-off event, it's usually not a cause for concern. However, if early or irregular periods persist, it might be worth consulting a healthcare professional to rule out underlying conditions or to discuss hormone imbalances.
