Usually bleeding means your not pregnant. Unless it was very light spotting, but a normal blood flow would usually indicate your not pregnant.

I agree. Whenever you bleed, it never means that you are pregnant. When you bleed you bleed. Periods can get abnormal sometimes. When it is abnormal most of the time then you should go to your doctor and ask what's happening or is everything okay.
