I am 65 had a hysterectomy when I was 45. This morning I saw blood (about a pea s size) in my underwear (the front part). I think it comes from urinal tract or virginal. I went to pee again and saw nothing on the toilet paper, it is clean. This evening I had a shower, I saw a little of blood on the towel and went to check, I saw a little bright red blood on the toilet paper. After one hour, I went to check it, it is clean again. I feel no pain or tightness or itching down there. May I know what is it about? Thank you.
