Daska86, don't worry (easier said than done!), just keep on with the daily Vagifem and blob of Ovestin and things will get better. I see from your previous posts that you have been given Canestin unnecessarily and this was bound to irritate and make you feel worse. It will take a bit of time for the local oestrogen to work, maybe a couple of weeks or more before you see any improvement. Let the treatment become part of your routine, like cleaning your teeth! After all, you will be doing this forever, but regular treatment will eventually make you feel more comfortable in the intimate area and will deal with UTI-like symptoms as well.
As to using too much or not enough, you sound just like me! Daily Vagifem, pea-sized blob of Ovestin, and you will get there.
To keep the vaginal flora healthy, try not to get water between the labia as this will flush away the good bacteria, so take showers not baths.
Let us know how you get on.
