A 57 year old lady attends the GP surgery for her Hormone Replacement Therapy (HRT) review. She has been on oral continuous combined HRT for the last 5 months and explains she has had some light irregular PV bleeding over the last month. She denies any other side effects and is keen to continue with HRT. She denies any flushes, night sweats or vaginal dryness.
What is the most appropriate management option in this patient?
