Why might withdrawal bleeding fail to occur after completing a five-day course of Duphaston, and what are the recommended medical approaches for managing the underlying hormonal imbalance?
After finishing Duphaston (dydrogesterone), it can take 7 to 14 days for bleeding to begin. If it doesn't occur, the most common reasons include an early pregnancy, low estrogen levels (meaning the uterine lining was too thin to shed), or hormonal fluctuations from stress or thyroid issues. As a first step, I gently recommend taking a home pregnancy test. If that is negative, please consult your doctor. They can run simple blood tests to check your hormone levels and may recommend an ultrasound or a tailored hormone therapy to help restore your body's natural rhythm.
