Hi! I Am 60 Years Old. I No Longer Have

Hi! I am 60 years old. I no longer have periods. The other day I suddenly started bleeding. It lasted all afternoon and night. It was about the amount of a regular period for me. I also had pain and pressure in my pelvic area along with a sudden urgency to urinate. I am a DES daughter and I had cervical cancer because of it when I was 22. I have an appointment with my GYN in a week and a half and I am trying not to over react. Your thoughts?
