Vagufem Low - anyone done trial of this who is Hormone Receptor +

Just started it after my surgeon checked with my oncologist at my last check up. I have had almost 6 years of anti hormone treatment. Back on Tamoxifen this year after just over 3 years on Femara. My symptoms only started on Femara (Tamoxifen for 2 years before that). Am very hopeful that it will help but too early to tell yet. 
I did feel a bit nervous about it but have put my trust in my oncologist giving the go-ahead. They are the experts.
