You might not be getting enough oestrogen down there. When the vaginal atrophy is bad every day treatment is usually required until you start to feel the benefits. 2 months is not long perhaps another month you might start to feel better, trial and error dealing with this awful condition.
But as an example I use Vagifem pessary and an oestrogen cream used topically every day with a feminine moisturiser thrown in the mix. Three years on and I am free of all the symptoms, you will get there in the end with constant VA treatment.
