I had 2 periods and 1 month. My first week its brown (Spotting) blood. Then the next week its bright red blood with blod clots the size of a silver dollar coin. This been happening for the pass 3 months. I am 29 years old. I am afraid. Do you suggest I go to a doctor. Please help

I would suggest a visit to your doctor. Brown blood usually indicates old blood that your body is filtering out of your system. But brown blood can also be an indication of something else, and the fact that it's happening every month, between periods, is reason enough to get it checked out.
