Why is there blood only on the top portion of my tampon, but when it's removed, there is no blood when I wipe, on a pantyliner, or in my underwear. I've been using tampons because my period is 9 days late and I've been experience back/stomach cramping, breast tenderness, mood swings, and pain in my legs. I'm sure it's coming due to discharge, but not sure when. I've had a Leep procedure, d&c, and come biopsy back in March 2010 due to CIN 3. I spot most days during the month and am concerned some abnormal cells have come back.
