I was on Vagifem for years before my breast cancer. They told me to stop taking it once diagnosed so I did. Afterwards about 5 months after diagnosis I got cystitis, then 2 UTI's (one of which I was actually passing huge blood clots) and simply put a very unhappy vagina and vulva. Went to the Gyn and she said I could use vaginal estrogen in much smaller doses. So I am using Estradiol cream, and it's ulta low dose and I am not even using the prescribed amount I'm using less. When I was going through menopause and well into my 60's I used 400 mg Indole 3 Carbinol and it was amazing, it totally got rid of my hormone imbalance. For breast cancer survivors they recommend DIM it can give you some mild headaches but some say it's as good as AI's but without the side affects and bonus it alleviates much of what you spoke of. DIM is a more stable version of Indole 3 carbinol. I feel your pain! I had to beg for this estradiol but I'm glad I did! Bonus I had a great checkup with the GYN, she got a great sample from my cervix and all looks good 🙂
