The Ovestin really helped with the VA, at that time I was in the peri stage, I then changed to Vagifem, but once post meno I needed systemic HRT plus the topical estrogen to control the VA, so I have done it a different way round to you.
When I was peri I had a couple of UTI infections, I had never had one before and since starting the Ovestin I haven't had one since, so about 6 years now. If I have run out of Vagifem and don't use it for a couple nights I do feel the need for a wee in the night and that's not normal for me.
