Hello~some ladies can start menopause in their thirties, it is called "Peri-menopause" and it can cause some of the same symptoms of menopause. I would see a gyn and ask for some tests to determine what your hormonal levels are. I also would start using "Bio-identical" progesterone cream. This matches your bodies progesterone perfectly, so there are no unwanted side effects like a person gets when they take the synthetic that most MD's prescribe. This has been known to help with vaginal dryness as well as other uncomfortable symptoms of Peri-menopause. Dr Jonathan Lee has an excellent book on it, you can probably order it on-line or get it at most book stores. It is called "What Your Doctor May Not Tell You About Peri-Menopause" it is excellent.
I had this too when I was early 30s up until a few months ago (now 37) bad enough I would tear from sex. Doctors saw nothing wrong. I stopped my anxiety meds. Cleared right up
Have you had a physical lately? They need to that and check your hormone levels. Sorry this happened.
