Why could there be spotting in a postmenopausal woman?

Hello doctor,

I am a 55-year-old woman. I stopped having periods three years ago. I visit my doctor every year for a gynecological physical and regular physical. My regular physical last year was great and my gynecological physicals have always been good as well except for uterine fibroids. My last GYN visit was four months ago and everything was fine. I have never had an abnormal pap smear. I have had the fibroids for almost 20 years. During my last GYN visit, all my tests were normal and my doctor said my fibroids were shrinking.

A week ago today I saw what I thought was a very small amount of blood on my poise pad. It has not happened since. This has never happened in the last three years since my last normal period. I also suffer from OCD and anxiety and I am always to myself. I am not even sure it was blood to be honest and of course, I will call my doctor and make an appointment for next week. It was not brown spotting and it was not bright red either. I do not have a UTI or pain in my abdomen or anything. Again, it was very, very small and light. I am thinking perhaps I had something on my hand and it touched my pad and I did not notice it. A little insight would be helpful. I am currently on Valsartan and Prozac.

Thank you doctor,

I know I have to see the doctor and I will. I already have an appointment.
