My period is typically like clockwork. This one (that I am still on right now) is not. Started 2-3 days early (which I know can happen) BUT has lasted for, as of today, 12 days. Its very light now, was only heavy-like for 2-3 days as it normally is. I have no known health problems to date. I am 31, overweight (but losing weight) and am worried something is wrong. I keep thinking it will stop and it just doesnt.
