Hi. I am 25 years old. I have normal periods for the most part, but this last period I noticed some odd trends. Ok, well right after my period. I had a normal 5 - 6 day period cramps and all that fun stuff, I thought it stopped, but apparently I was wrong. I had light spotting for the next 5 or so days, there may have been a day between where there was no bleeding activity - mostly bright red, but not heavy enough to the point where I needed a tampon or pad. I had lower back pain during this time. What does all this mean??

It means you should call your doctor. Could just be an abnormal period, which I have had my share of, but it could be something else.
