No chance of pregnancy and not on birth control. I've been on my period for 6 + months. I use pads almost exclusively unless I am bleeding heavily.  I have dark clots the size of a tampon, then bright red blood, and then it repeats.  I also have cramps randomly.  The women's center and my gyno isn't concerned unless I soak a pad an hour for more than 7 days.  The emergency room says the same thing. My general physician tells me that if the gyno & ER isn't concerned then I need to relax.  I can't pay for another doctor out of pocket for  another opinion.  This seems abnormal to me.  I guess I am just at my wit's end and needing to vent.
