I am a 64 year old woman, very healthy, no issues except arthritis. On rare occasions I have had very light vaginal spotting. Bright red blood. The first time it happened, 2 yrs ago, my doctor sent me for an ultrasound which showed nothing abnormal. Every once in a while - especially after straining while constipated, I see light staining of red blood. I don t think it s from hemorrhoids (which I have) but could it be??
