My period is crazy up and down, I didn't have one for almost 6 months I now that I am it has been nonstop for 2 weeks.

My bleeding is heavier than normal.
I am passing blood clots and my pads or tampons don't last with the flow anymore then for 1-2 hours, I soak through or overflow.

I think I may have dysfunctional uterine bleeding and I don't know where to go to find out or when it becomes dangerous or how to treat it.

Um. I would take this as serious right now and get to a doctor or ER. Soaking through a pad in an hour or two is dangerous.
