Vaginal dryness, to which your GP refers, actually affects the whole genitourinary area, and is more correctly known as GSM, Genitourinary Syndrome of Menopause. The vagina, labia, clitoral, urethral and lower bladder areas can all be affected. I think your progesterone only pill (Cerazette) might be implicated here, and it may be that you need some local oestrogen treatment. I suggest you join the private Vaginal Atrophy Facebook support group for more information and advice. One of their excellent and knowledgable moderators will know, and there will be other members taking a POP.
