Bloody nipple discharge following biopsies

Hi,

I had biopsies taken from both breasts 9 days ago. I have clusters of calcification in both breasts.

Today I have discharge from both nipples. The right one has thin, clear, yellow liquid with red stains of blood in. The left nipple has very dark, thicker blood coming from it. It looks black but is actually just very dark red/brownish. 

I have a phone appointment booked for Tuesday 12th for my results but Tuesday feels like a long way off to wait to ask if this is normal.
