By Dr. Soma Kumari – Consultant Gynecologist, Gurugram. If your periods have become irregular after 35, you're not alone. As women approach their late 30s, hormonal changes can start to shift the menstrual cycle. You might experience longer or shorter cycles, missed periods, heavier bleeding, or spotting. These could be early signs of perimenopause — the phase leading up to menopause — but they can also point to issues like thyroid imbalance, fibroids, PCOS, or high stress. If your cycle feels unpredictable or your symptoms are disrupting your daily life, it’s a good idea to check in with a gynecologist. Understanding what’s behind the change can help you take control of your health and plan ahead. Dr. Soma Kumari offers compassionate guidance and personalized care to support women through every life stage.
