anderina, using your Vagifem until you go to the hospital next week (you say you are going for hysteroscopy) though your nurse did confirm vagifem can effect fibroids, I don't think its going to effect your fibroid that much at this stage, or try see your doctor for a prescription for Gynest Cream (estriol) which may being relief, until you decide if you are going for a hysterectomy.
Non prescription include Vagisil
•Replens MD®, Sylk® and Hyalofemme® are non-hormonal vaginal moisturisers

Using vagifem etc when you have a large fibroid is a personal choice as I said in my previous posts, its also about awareness and about the pros and cons, and your own personal reactions to it.
