Bleeding after biopsy

Hi! 

I've just had a ultrasound and biopsy due to bloody nipple discharge, wasn't expecting anything from it and thought it was due to stopping breast feeding in June. They found a lump during the scan so I had a biopsy yesterday. They said it didn't change shape after the biopsy so they don't think it's milk and think it's a hard lump. 

My main question is should I expect bleeding (from nipple) after the biopsy? My original bleeding stopped a few weeks ago but re started an hour after the biopsy. 

Feeling a bit lost and hating the wait!

Thanks for any replies xxx
