I have been seeing a cancer gyn for over one year. I have an ovarian mass on my left ovary. I have had breast cancer and am taking tamoxifen. My last period was very strange for me. When changing my tampons, there was only blood on the right top side. What does this mean? Could my left ovary be shutting down. I have had the FSH blood test done and my number was 8.5.

Thank you for any input!!
