I'm sorry to hear about your recent dx's
I have no experience with the BV but I did find a link that contains some info on it's symptoms, causes, treatment & prevention:
Bacterial Vaginosis overview
Perhaps something in there can help you with your questions & concerns...
As for the Menopause, unfortunately, yes it is very possible for you to be experiencing it. When the Uterus is removed, sometimes the blood flow to the Ovaries is altered/damaged resulting in our Ovaries having diminished function or to shut down all together <sigh> The good news is that they will still continue to produce small amounts of those much needed Hormones
Which, for some, can be easier to supplement for what is lost than to totally replace them!
I am 4 yrs Post-TAH in which I retained both Ovaries at the time opf my Hyst. Due to some complications from Adhesions, I lost my right Ovary at 12 weeks Post
I underwent an emergency surgery for Bowel Obstructions about 7 weeks after the RSO. During one of my surgeries, the blood flow to my left Ovary was altered to the point of it being nonfunctioning. So I was anywhere from 3-5 months Post when mine occurred. Here are a couple links that I thot may be of some further insight to you on how/why this happens:
Ovarian Failure Following Hysterectomy
Premature Ovarian Failure
There is also some good info in our Resources forum:
Good Luck with everything
I hope that infection clears up soon...Pls keep us posted on how things are going...(((hugs)))
