The watery discharge is a symptom of VA. You can use 5 Vagifem a week, which is equivalent to the old dose of 2 x 25 mcg pessaries (we only have the 10s now). You could also ask for some Ovestin cream to apply to the outside. Keep up the treatment, as VA can take a few months to get on top of. It is for life so needs regular treatment. One of the Yes products (VM or OB) or Sylk might help. Have a look at their websites as I think they will send you samples.
