Hi hystergirl, just a quickie to add to what the others have said - I found both Yes VM & Yes OB irritant, but get on OK with Yes WB & better still, Sylk. I also use a thin smear of the weaker of the 2 Estriol creams (externally) daily + Vagifem 5 nights a week. I find Vagifem doesn't dissolve well so apply a blob of Sylk to the tip of the applicator to help it adhere to the vaginal wall. Hope you make progress. Perseverence is key with VA treatment.
Oh forgot to say - if you are on systemic HRT & have yet to try Testosterone, that can help with GSM. I've had oophorectomies & later total hysterectomy & do find T improves systemic dryness.
