Blood after biopsy

I'm 38 and had slightly elevated PSA of 2.8 (for my age)
recently. Since my father died of prostate cancer at an early
age, my doc sent me to a urologist for a needle biopsy one week
ago. The urologist called yesterday to say biopsies negative,
so he plans to do DRE and PSA two or three times each year.
My question... my wife and I noticed lots of blood last night
after ejaculation (my first since the biopsy). Is this to be
expected after biopsy, and if so, how long does it continue? Tweet
