Hello, what is your age ?
When were your ovaries removed and why?
Do you still have a uterus?
Tell me about the bleeding that you are seeing?
Thanks for the extra information. Just a couple of questions... have you been on any birth control or hormone pills?
Do you ever have periods or bleeding?
Are you at your ideal weight or are you heavier?
With an intact uterus then it can still be possible for some bleeding to occur. Although the absence of ovaries means no estrogen from the ovaries, it is possible for the body to produce some peripheral estrogen in adipose tissue. This can lead to thickening of the uterine lining over time.
Ideally you need a ultrasound scan to check the lining of the uterus.
Other possible causes of bleeding from the vagina can include cervical erosion, polyp or vaginal atrophy leading to bleeding from vaginal walls (especially after intercourse)
Another possibility of bleeding that is seen on underwear is that a clot was passed from the bladder, and this might be related to the kidney stones.
Without any hormones then you do need to discuss long term bone protection with your doctor if you have not done this already.
