I am just 42 and suffer with VA. I've posted my journey in the new members section. My recent symptoms (last year and a half) have been vulva focussed (itchy/burning sensations plus redness on vulva area) but I wanted to mention that I also have microscopic hematuria or blood in the urine.
The first time it came up was back when my periods became heavier and I had iron deficiency (start of perimenopause?). The doctor did a urine test as part of a general health check and then sent me for a kidney/bladder ultrasound and all was ok. I would have been 36 at that time.
Later when I was 39 I started having short spells of having a painful bladder (it felt very full and sore even after going to the toilet). I mentioned the earlier blood in the urine and was retested. It was found again, so I was sent first for a CT scan (to check for bladder/kidney stones) which was clear and then onto a Urologist who was very reassuring and not particularly concerned about the blood. He asked me to provide a urine samples for 3 consecutive days to check for signs of cancer. This was clear and I coincidentally didn't get the symptoms again after that.
Earlier this year I was getting up during the night to go to the toilet and went fairly frequently during the day.
Now I have been successfully treated with vaginal estrogen (Ovestin) I now assume the microscopic blood was the very early days of VA working on me. I have read online (somewhere, cannot remember) that blood in the urine can be a symptom of VA / low estrogen down there but it doesn't seem to get much of a mention. I was therefore very interested to see your post!
Incidentally the daytime frequency has greatly improved and nighttime toilet runs are non existent since using the vaginal estrogen.
Like your doctor, mine did not think my vulva symptoms were related to the menopause (asked her 1st visit

) Similarly, my mum became menopausal in her late 30s too.
You're not alone. Ask for vaginal estrogen. Good luck.
