Bloody discharge from breasts .. not milky or serous. Frank blood.

I am 43 yrs. old, had a total hysterectomy one year ago, I am on hormone replacement at present.  In January, I had two days of spontaneous bleeding from rt. breast.  Went to GYN, had mammo and ultrasound both were negative.  Now, in April, had several days of spontaneous bleeding from left breast.  They want to do a ductogram, however they said I need to be bleeding ... for the best visability.  Well, I bled again on Sunday (left breast), when the center is closed, so now they suggest I see a surgeon for a ductal biopsy?  Any recommendations?  I have an appt. with the surgeon next week.  I'm a bit worried, any info would help.
