Having abdominal pain and bleeding very heavily. Blood is dark and rather "chunky." It is not time for my cycle. Another detail; when I use a tampon blood only seems to absorb on one side. The side is consistantly the left. I have been told by both my Family MD and my OBGYN that this will soon subside, and at my age there is not much to worry about. Do you have any comments on what might be causing this?
