Many women notice cycle changes before menopause and ask why is my menstrual cycle getting longer. A lengthening menstrual cycle can occur during the perimenopause transition as hormone levels fluctuate unpredictably. Estrogen and progesterone may rise and fall at irregular intervals, which can affect ovulation and cycle length. Weight changes, stress, and lifestyle habits can also contribute to these irregularities. When individuals notice persistent cycle changes along with fatigue, weight gain, or mood fluctuations, consulting a medical provider may help identify underlying hormonal shifts. Clinics like Align Health and Menopause often evaluate hormonal health to determine whether lifestyle interventions or medical treatments may be beneficial.
