I am 52 years old and have not had my period for 2 months. I began again a few days ago with light to moderate to light bleeding. I was extremely uncomformtable all night and had the feeling of pressure when I went to eliminate. When I awoke I was still not feeling well and had pain while I sat down. While standing and walking around I felt a gush of liquid come out of me. It was blood. As I sat on toilet a great deal of blood came out as if in the heavy part of your period. I am feeling fine now and am back to a light bleeding. Should I be concerned?
